Abstract
Nature Refuges encompass the second largest extent of protected area estate in
Queensland. Major problems exist in the data capture, map presentation, data quality
and integrity of these boundaries. The spatial accuracies/inaccuracies of the Nature
Refuge administrative boundaries directly influence the ability to preserve valuable
ecosystems by challenging negative environmental impacts on these properties. This
research work is about supporting the Nature Refuge Programs efforts to secure
Queensland’s natural and cultural values on private land by utilising GIS and its
advanced functionalities. The research design organizes and enters Queensland’s
Nature Refuge boundaries into a spatial environment. Survey quality data collection
techniques such as the Global Positioning Systems (GPS) are investigated to capture
Nature Refuge boundary information. Using the concepts of map communication GIS
Cartography is utilised for the protected area plan design. New spatial datasets are
generated facilitating the effectiveness of investigative data analysis. The geodatabase
model developed by this study adds rich GIS behaviour providing the capability to
store, query, and manipulate geographic information. It provides the ability to
leverage data relationships and enforces topological integrity creating savings in
customization and productivity. The final phase of the research design incorporates
the advanced functions of ArcGIS. These functions facilitate building spatial system
models. The geodatabase and process models developed by this research can be easily
modified and the data relating to mining can be replaced by other negative
environmental impacts affecting the Nature Refuges. Results of the research are
presented as graphs and maps providing visual evidence supporting the usefulness of
GIS as means for capturing, visualising and enhancing spatial quality and integrity of
Nature Refuge boundaries.

Chapter 1: Introduction

1Chapter 1: Introduction
“A protected area is an area of land and/or sea especially dedicated to the
protection and maintenance of biological diversity, and of natural and associated
cultural resources, and managed through legal or other effective means” (IUCN
1994).
Protected areas are parts of the earth that are sheltered from development or from
other activities likely to damage their wildlife, ecological processes, archaeological
resources and landscape. Biosphere Reserves and World Heritage Sites are
internationally designated areas. Other areas which have particular natural, cultural,
aesthetic or recreational value are national parks, nature reserves and nature refuges.
They are all seen as means of delivering environmental gains such as wildlife
conservation, environmental protection, archaeological and cultural values, therefore
large-scale or potentially damaging development is generally strictly controlled
(Clarke 1997).
Chapter One outlines the research problem, the research aim and the approach to
spatially representing Queensland’s Nature Refuges. Historically protected area
boundaries have been used to segment and structure the spatial ambience to support
the environmental management and planning procedures. Furthermore these
boundaries support the political and economic decision making process. Currently in
Queensland there are over 8.7 million hectares of protected areas. Nature Refuges
comprise the second largest expanse of Queensland’s protected area estate. This study
sets out to determine how Geographic Information Systems (GIS) can support the
management of the Nature Refuge protected areas.
DERM (The Department of Environment and Resource Management), 2005
categorizes Nature Refuges as classes of protected area that can be created under the
Nature Conservation Act 1992. Nature Refuge’s include areas of freehold and
leasehold land that are the subject of a “Conservation Agreement”. A Nature Refuge
Chapter 1: Introduction
Page 2
acknowledges a commitment to preserve land with significant natural and/or cultural
heritage values in perpetuity.
A Gazetted Nature Refuge becomes part of a network of protected areas contributing
to the conservation and protection of Queensland’s biodiversity. National parks alone
cannot maintain the diversity of plants, animals and cultural variety found in
Queensland. Therefore landholders can play a vital role in protecting the state’s
biodiversity by initiating nature refuges on their property. A voluntary agreement is
established between a landholder and the Queensland Government that acknowledges
a commitment to preserve land with significant natural and/or cultural heritage values
in perpetuity. Each Nature Refuge agreement is negotiated directly with the
landholder and tailored to suit their management need. Every Nature Refuge plays an
important role in the conservation of Queensland’s environment. They protect
remnant bushland, native flora and fauna, corridors for wildlife and places of historical
or cultural significance (DERM 2008).
1.1 BACKGROUND
The first Nature Refuge was gazetted in 1994 since then there has been a significant
increase in their numbers throughout Queensland. In 2005 the number of Gazetted
Nature Refuges rose to two-hundred properties protecting 400 000 hectares of land.
At this point it became obvious that the Nature Refuge program was dealing with a
vast amount of geographic data and current systems used to capture this information
were not adequate. The project management of a Nature Refuge Gazettal consists to
a large degree as a spatial component. One of the major problems limiting the
integration, comparison and transfer of this boundary data was its preparation. In the
majority of cases the protected area boundaries have been created by individuals to
meet their specific needs, usually and as in the case of Queensland’s Protected Areas
Estate the mapping is carried out in non-spatial platforms such as Adobe Illustrator
with no spatial coordination. Therefore a considerable amount of data manipulation is
required in order to make use of this data in a spatial environment.
Chapter 1: Introduction

1.2 RESEARCH PROBLEM
The current endeavours representing the Nature Refuge boundaries directly influence
the Nature Refuge Programs ability to preserve valuable ecosystems by challenging
detrimental factors affecting these properties. Data collection techniques, map
presentation and data integrity are the three major factors affecting a timely gazettal
process. The focus of this research will be on these constraints.
Data collection - Currently two methods exist to assemble boundary data. The first
method is collecting field data using handheld Global Positioning System (GPS) units
with a manufacturer’s horizontal accuracy specification of around ±15m. Types of
field data collected include unsurveyed sections of the nature refuge boundary,
internal zone boundaries and exclusion areas. The second method consists of aerial
photo interpretation this process is used when ground-truthing is not possible as the
area is not accessible.
Map Presentation - The CAD revolution began in the early 1980s. It changed the
way the surveyors, engineers, planners and many other professionals carried out their
drafting work. Years after this technology breakthrough the GIS attracted little if any
attention. CAD systems were used to capture GIS data and many organisations used
CAD for mapping geographic data (Korte 2001). The design of Nature Refuge Plans
were also part of that revolution produced as a ‘bi-level’ or two colour image within
the AutoCAD environment they limited geographic information processing and
created numerous complexities for end users. Map clarity is one of the main concerns
Cartographic standards are lacking and the vital Nature Refuge internal and external
boundary information cannot be distinguished easily. As a result the maps are often
misinterpreted by the map reader. Appendix 1 illustrates the Nature Refuge Protected
Area Plan produced in AutoCAD.
Data Integrity - Problems arose when incorporating the boundaries into a GIS
environment. The process created alignment inaccuracies and more data manipulation.
Due to these, spatial data quality and integrity became a critical issue. The boundary
Chapter 1: Introduction
Page 4
information that evolved from AutoCAD was clearly not designed to be applied to a
wide range of applications.
The accurate spatial representation of Nature Refuge boundaries is clearly the
Department of Environment and Resource Management’s obligation to both the
government and private sector. Once gazetted Nature Refuges become part of a
network of protected areas, in 2009 the total number of Gazetted Nature Refuges was
366 protecting over 700,000 hectares across the state of Queensland. This research
will focus on the need to improve the current methods of the Nature Refuge Mapping
Program, by using the GIS based approach. The study will reconsider common GIS
features and propose several new functionalities.
1.3 AIM OF RESEARCH
The aim of this research is to adopt a scientific approach and develop a GIS gazettal
framework for the Department of Environment and Resource Management that will
streamline the gazettal process of Nature Refuge’s in Queensland. The intent is to
address the current major factors affecting a timely gazettal by using the capabilities
of the desktop GIS as a methodological tool for the presentation and analysis of
Nature Refuge boundary.
1.3.1 Objectives
The following research objectives are identified to achieve the aims of this
study:
Investigate and utilise GIS and its advanced functionalities to enhance the
mapping component of the Nature Refuge Program;
Develop a digital database that places Queensland’s Nature Refuge boundaries
in a spatial environment that facilitates analysis and effective spatial data
interchange between the States/Territories and the Commonwealth; and
Evaluate the framework through meaningful analysis.
Chapter 1: Introduction
Page 5
1.3.2 Hypothesis
The hypothesis of this thesis is that GIS can streamline the gazettal process and
improve the spatial integrity and quality of Nature Refuge boundaries.
1.4 METHODOLOGY
The use of appropriate methodology when designing and analysing complex spatial
datasets is imperative to the accuracy and validity of the final outcome of any GIS
based research. The methodology outlined below has been devised with the main
research objectives in mind and is designed to prove/disprove the hypothesis stated
above.
The study objectives will be achieved through the following research design:
Conduct an environment scan to identify changes and trends in the field of
GIS technology and to justify the research design approach;
Build the system that will streamline the gazettal process using the ArcGIS
Server and Desktop GIS ArcInfo 9.3. software;
Merge data from many different sources, scales, and dates and recombine
them in a powerful display and analytical environment; and
Test and evaluate the system
1.5 SIGNIFICANCE
The Queensland Government’s plan for Tomorrow’s Queensland Q2 has been framed
around five ambitions for the whole state. The environmental challenges are identified
through the second ambition Green “We want to protect our lifestyle and
environment”. One of the long-term measurable 2020 targets for Green is to protect
fifty percent more land for nature conservation and public recreation (Department of
the Premier and Cabinet 2008). This research is unison with the Governments 2020
vision. The GIS gazettal framework proposed by this study will facilitate the
management of existing Nature Refuges; enable spatial monitoring and development
of future Nature Refuges, from the initial tender phase to the final gazettal stage.
Therefore having the ability to resourcefully exchange and integrate these boundaries
Chapter 1: Introduction

in a spatial context within DERM, significant steps towards promoting conservation
on private land will be accomplished in a more efficient and timely manner.
1.6 THESIS STRUCTURE
The remainder of this thesis is organised into 7 chapters. Chapters 2 to 4 deal with the
literature review and methodology. Chapters 5 and 6 present the results and
evaluation, while Chapter 7 lists the conclusions. A more detailed summary of each
chapter is given below.
Chapter 2 reviews research and developments related to the field of GIS justifying
the research design approach. The chapter is divided into two main topics; the first
describes GIS fundamentals, commencing with the basics of GIS, the mapping
component of GIS and concluding with GIS analysis. Examples of various scenarios
where the use of the GIS has proved to be an invaluable tool will be presented. The
second topic offers an insight into the use of GIS in environmental conservation
mapping and current Queensland infrastructure projects that are supported by GIS.
Chapter 3 describes the development of the first three phases of the GIS gazettal
framework. Structured into three main themes it presents how to capture Nature
Refuge boundaries, how to construct the protected area plans and how to create
Nature Refuge spatial datasets. Outlined are new methods for collecting, constructing,
presenting and storing the boundary data in preparation for analysis. Chapter 3 is
fundamental to the success of the research as the current major factors affecting a
timely gazettal are addressed by using the capabilities of the desktop GIS.
Chapter 4 builds on the processes described in Chapter 3 and guides the research
design from mapmaking to the true power of GIS. A Nature Refuge Geodatabase is
developed placing Queensland’s Nature Refuge boundaries in a spatial environment
that facilitates analysis and promotes effective spatial data interchange. The main
focus of this chapter is data integrity, analysis and process modelling. The latter part
of the chapter tests the GIS grazettal framework through multiple queries. The query
answers are required for reporting purposes and Government decisions to be made.
Chapter 1: Introduction
Page 7
Chapter 5 presents the research results, exhibits the new and improved mapping
component of the Nature Refuge Mapping Program. The Nature Refuge Protected
Area Plan, the Gazetted, Proposed and Potential spatial datasets are all presented as
high quality cartographic outputs of the GIS system. In addition, this chapter presents
the Nature Refuge Geodatabase model, the Mining model and the results of various
other spatial queries.
Chapter 6 evaluates the GIS gazettal framework, discusses and summarises the
benefits of this study to the Public and Private Sector. The benefits are correlated to
the key customers of the spatial Nature Refuge dataset. Examples are provided
demonstrating that GIS can be used as a methodological tool for: decision support,
reporting and tracking performance within the Nature Refuge Branch. Spatial data
compliance to other Government systems and the capacity to spatially network Nature
Refuges streamline the gazettal process of Nature Refuge’s in Queensland.
Chapter 7 presents final conclusions and a summary of the key research tasks and
major contributions of the research. The chapter closes with the limitations of the
study and recommendations for future research.

“Call it what you like – the resurgence of geography, the reinvention of maps, or
the vindication of cartography – but the increasing prominence of geographic
information systems (GIS’s) becomes more pronounced every day” (Padilla 2008 pg.32)
Chapter two begins by presenting the basic concept and methodologies of GIS. The
review has been undertaken to justify the research design approach that will structure
the remainder of the thesis. The chapter also examines key literature related to
Geographic Information Systems and various aspects of the use of GIS applications to
emphasise the importance of this technology in the field of environmental protection
and conservation.
2.1 BACK TO BASICS
Geographical Information Science is a field of expertise that spans across multiple
disciplines. Geographic Information System is the equipment used in this field and in
order to successfully operate it one has to think like a Geographical Information
Scientist (Clarke 1999). The system consists of hardware and software designed for
the storage, retrieval; mapping and analysis of geographic data, there are several
different definitions for the meaning of GIS. Dating back to 1979 the following is a
summary of how some pioneers in the Geographic Information Science defined GIS.
“A Geographic Information System is a unique case of information systems where the
database consists of observations on spatially distributed features, activities or events,
which are definable in space as points, lines or areas. A geographic information
system manipulates data about these points, lines and areas to retrieve data for ad hoc
queries and analysis” (Dueker 1979).
Chapter 2: Environment Scan
Page 9
“Geographic Information Systems (GIS) is a computer – assisted system for the
acquisition, storage, analysis and display of data that is geographically referenced or
related to real-earth coordinates” (Clarke 1986).
“A powerful set of tools for storing and retrieving at will, transforming and displaying
spatial data from the real world for a particular set of purposes” (Burrough 1986).
“An information system that is designed to work with data referenced by spatial or
geographic coordinates. In other words, a GIS is both a database system with specific
capabilities for spatially-referenced data, as well as a set of operations for working
with the data” (Star and Estes 1990).
It is a sophisticated model capable of developing, using, visualising and analysing the
geospatial data (ESRI 2004b).
Apart from mapping GIS is used for analysis, modelling and decision support in a
range of application areas. The ability to perform spatial analysis and the capability to
combine spatial and non-spatial data for analysis modelling and decision support are
the main features that differentiate GIS from other information systems (Karimi and
Blais 1997). The core element of a GIS is the use of a location referencing system so
that data about a specific location can be analysed in its relationship to other
locations. The coordinate systems that are commonly used are plane and global and
the system is capable of easily transforming from one referencing system making it
possible to combine data stored in different forms (Church 2002).
The planning field was the first discipline to utilise the principles of GIS through the
creation of thematic maps. Data was extracted from one map and placed on another.
In 1922 using the principle of a GIS operation that is known in modern GIS as
overlay a series of regional maps were prepared for Doncaster, England. These maps
showed general land use overlayed with contours of traffic accessibility. In 1950
Jacqueline Tyrwhitt wrote a landmark chapter called “Surveys for Planning” in the
Town and Country Planning textbook. Land elevation, surface geology,
hydrology/soil drainage and farmland were combined into a single map. In 1962 the
map overlay advanced when two planners at the Massachusetts Institute of
Technology added weighting by making the overlays different in their importance with
respect to each other. It was the thematic maps that lead cartography towards GIS
(Clarke 1999).
Chapter 2: Environment Scan
Page 10
More recently the rapid growth and use of GIS is a result of several unified factors.
The massive cost reductions in computer technology resulted in GIS software
products being available from commercial vendors and universities. Computer
workstations are capable of handling many of the computational, retrieval, and
storage problems within a reasonable amount of time and at reasonable cost. The
graphical displays and plotters are more modernized and fast, producing high-quality
output. Finally geographic data custodians particularly government agencies local
state and federal are more open to data-sharing at reasonable cost. The use of remote
sensing has expanded, especially in environmental monitoring, and this has led to the
need for systems that are capable of handling large amounts of data as well as serve as
a major source of land coverage information. The emergence of the satellite based
Global Positioning System (GPS) has made it easy to collect attribute data along with
its location at relatively low cost and with relatively high accuracy. All of these factors
played significant roles in the growth of the GIS industry (Church 2002).
Geographic objects in GIS can be represented as one of the three shapes only point,
line or polygon. This data is known as “vector” data. Vectors have the advantage of
accuracy they are used to define spatial objects for example towns, roads or
boundaries. The objects are then linked to attributes describing their characteristics.
As vectors are entered into the system as points, lines and areas they can then store
the features characteristics as properties in the attribute tables. These are the vector
properties used in analysis (Clarke 1999).
Geospatial data with properties like slope, temperature, elevation is represented as
surfaces or “raster” data. This data has numeric values rather than shapes and
represents the intensity of that particular property in geography. In the raster model
the earth is treated as one continuous surface and each location is represented as a cell
(ESRI 2004b).
Conversions from vector to raster are simple to carry out. The raster to vector
conversion on the other hand is a process of converting an image into vector-based
features and is more complex. The raster to vector process will be used in this study
to retrieve boundary information from hardcopy Protected Area Plans.

2.2 GIS AND MAPMAKING
Analytical cartography arose in the 1960s as a by-product of geography’s quantitative
revolution wherein spatial statistical methods gained widespread application
throughout the parent discipline (Tobler 1976) (Tobler 1970).
Many researchers in the fields of cartography and GIS believe there is significant
overlap between the two as both fields are built on a unified spatial theory foundation
that includes common components such as graphic data structures (raster and vector)
and various mathematical and analytical methods. Some suggest that the significant
difference between analytical cartography and GIS relates to the cartography’s focus
on practical applications while GIS is predominantly focused on developing a base of
analytical theory (Moellering 1991). The focus of this study will be both on
cartography and GIS as they are equally important to the correct spatial
representation of Nature Refuge boundaries. Phase 2 of the GIS gazettal framework
develops the cartographic plan. Using the concepts of map communication it will
make the Nature Refuge Protected Area Plan useful and simple to understand by the
map reader.
In the past traditional cartographic mapmaking process failed to include the aspect of
working with geographic data collected by others. Modern geography and
cartography however form a strong relationship by sharing many principles,
conventions and basic concepts. The most significant relationship they formed was the
introduction of the GIS technology in the early 1960s. In most GIS work scenarios a
lot of data has already been prepared making cartographic presentations a totally
separate practice. Nevertheless geography and cartography have always been
interdisciplinary fields and many other disciplines continue to draw on their
knowledge. Today GIS has become a strong field and discipline of its own. Many
academics acknowledge the change in the relationship between geography and
cartography but question the future of cartography, assuming technology can do all
cartographic tasks. However concepts established over thousands of years still remain
significant. Regardless of what technology is capable of, professionals will always
need to produce the highest quality maps and others will benefit from their concepts
and skills (Harvey 2008).
Chapter 2: Environment Scan

Many GIS promoters argue that GIS maps are intended only as quick intermediate
views of data rather than final polished maps, however the value of any GIS as a
visualization tool is greatly compromised if these quick views fail, for design reasons,
to communicate the true nature of the spatial information they represent (Mersey
1996).
In this context, it is suggested that map design plays a pivotal role in the effectiveness
of investigative data analysis (Mackaness 1996).
In general maps can fail because of the following factors:
Poor design
Wrong choice of symbols or colours
Wrong projection
Poor generalisation
Poor visual balance
Poor legend
Poor registration (ESRI 2004a).
Map clarity plays the key role in understanding and interpreting the collected data if
the cartographer does not have the ability to perceive or correctly portray the
environment or the information obtained from it the map can easily be misinterpreted.
It is, therefore up to the cartographers to develop the design tools that facilitate data
exploration (ESRI 2004a). Chapter Three of this thesis presents Phase 2 of the GIS
gazettal framework. This phase constructs the Nature Refuge Protected Area Plan in
GIS. The map template, map symbology and map quality standards developed by this
study will be presented.
Geographic data cannot be represented by simple geometries as used in Computer
Aided Design (CAD). Areas covering more than a few square kilometres have to
allow for the curvature of the earth. In order to represent the surface of the earth on a
flat piece of paper, the map area is projected onto the paper. Map projection is about
Chapter 2: Environment Scan
Page 13
projecting points from a sphere on to a flat surface. The main difference between
projections is the kind of distortions they introduce to the data (Albrecht 2007).
Once the map projection is established it is necessary to set up a coordinate system on
the map that will allow a point to be described in X-Y space. There are several types
of grids (or coordinate systems), used to divide the earth’s surface.
The Geographic Coordinate System, is one of the most common used coordinate
systems, it uses degrees of latitude and longitude to describe a location on the earth’s
surface. Lines of latitude run parallel to the equator and divide the earth into 180
equal portions from north to south. The reference latitude is the equator and each
hemisphere is divided into ninety equal portions, each representing one degree of
latitude. The Gazetted, Proposed and Potential Nature Refuge datasets will be in the
GDA 94 Geographic Coordinate System.
The Universal Transverse Mercator projection is one of the most popular
projections as it allows precise measurements in meters to within 1 meter. The
Universal Transverse Mercator (UTM) projection is used to define horizontal,
positions world-wide by dividing the surface of the Earth into 6 degree zones, each
mapped by the Transverse Mercator projection with a central meridian in the centre of
the zone. UTM zone numbers designate 6 degree longitudinal strips extending from
80 degrees South latitude to 84 degrees North latitude. UTM zone characters
designate 8 degree zones extending north and south from the equator. Eastings are
measured from the central meridian (with a 500km false easting to insure positive
coordinates). Northings are measured from the equator (with a 10,000km false
northing for positions south of the equator)
(Dana 1995).
When creating the protected area plan the individual Nature Refuge boundary will be
designed in the Map Grid of Australia (MGA) projection, Zones MGA54, MGA55 or
MGA56 depending on the boundaries location within Queensland. When integrating
the individual boundaries into the Nature Refuge spatial dataset they will be re-
projected to the Geodetic Datum of Australia GDA94.
GIS cartography has many advantages it can be cost-effective, accelerates the
cartographic process, provides screen and interactive maps and it can show dynamic
Chapter 2: Environment Scan
Page 14
phenomena in real time. The cartographic design is a complex task and a highly
creative mental activity that requires thinking in visual terms, such as visual balance,
visual hierarchy and visual levels (ESRI 2004a).
2.3 THE FUNCTIONS AND ANALYSIS OF GIS
A variety of tasks can be performed using the GIS technology. Data input, data
manipulation, data management, data analysis and data visualisation are the core
functions of GIS. Clarke (1999) categorised and described these functions as the
“critical six” must have functions for the software to qualify as a GIS.
Not much has changed since Clarke’s categorization of GIS functions. In 2009 ESRI
still identifies: capture, store, query, analyse, display and output as the main GIS
functions. This research will investigate the capabilities and functions the GIS offers,
with the intention of utilising these capabilities to assist the Nature Refuge Programs
efforts in promoting conservation. GIS will be used to its full capacity as it will
perform the six fundamental functions. Additionally it will be the main cartographic
tool for the final presentation of high-quality maps (ESRI 2005). GIS is used to
provide information to answer questions and make decisions. The analysis method
selected to provide an answer will depend on the type of question asked. Action is
then taken based on the results of the analysis.
Figure 2-1 depicts the five steps of ESRI’s (2005) analytical process. This process
will be applied in the latter part of this thesis when analysing the Nature Refuge spatial
datasets.
Figure 2-1 The Analytical Process
Chapter 2: Environment Scan

2.4 GEODATABASES AND SPATIAL MODELS
Figure 2-2 illustrates the geodatabase as a collection of geographic datasets, designed
to store, query, and manipulate geographic information and spatial data (ESRI 2006).
It provides the ability to leverage data relationships, enforce data integrity and create
intelligent features. Within the Nature Refuge spatial database, vector data will be
stored as point, line and polygon geometry data type with an associated spatial
reference system (ESRI 2006).
Figure 2-2 Geodatabase Data Types
Understanding geodatabase elements is important for building a sound design (Arctur
and Zeiler 2004).Vector data is stored in the geodatabase as thematic layers otherwise
known as feature classes. The Gazetted, Proposed, Potential and Historic Nature
Refuges will be stored in the geodatabase as a collection of geographic features with
the same polygon geometry type. They will be grouped together within a feature
dataset with the same coordinate system to model geospatial relationships between
them.
Chapter 2: Environment Scan
Page 16
In the geodatabase raster data is stored as raster datasets; each image is stored as its
own thematic layer. Multiple rasters can be grouped into a raster catalog (a collection
of raster data), or if the rasters are adjacent to each other, they can be mosaicked into
a single raster dataset (ESRI 2006). Figure 2-3 shows a general geodatabase structure
and the various types of elements that can be stored.
Figure 2-3 Geodatabase Elements
Zhou et al. (2006) used the GIS technology to analyse the offshore marine placer gold
deposits at Nome, Alaska. The primary task of the project was building geodatabases.
The digital data was in many different formats so in order to store and integrate the
information two relational geodatabases were created. The Integrated Geodatabase
(IG) was used for data management, information query and served as a warehouse to
store various geological data such as borehole, bedrock geology, surficial geology and
geochemical data. The second geodatabase R2.5DG was generated based on the IG
and was used to estimate gold resources, define orebody boundaries and perform
grade interpolation. The R2.5DG facilitated data management, retrieval and
integration and was used to perform advanced analysis tasks such as queries,
geostatistical and numerical modelling (Zhou et al. 2007). Similarly the Nature Refuge
Chapter 2: Environment Scan
Page 17
Geodatabase will be created to store and manage all data relating to internal and
external Nature Refuge boundaries. It will add intelligence to the spatial boundaries
and enforce data integrity between them for a more comprehensive and accurate
spatial product.
Three approaches exist for using a GIS with application models. Each approach has
its advantages and disadvantages (Karimi and Blais 1997).
1. Using the GIS and models as separate systems, with the output of one being
fed into the other. The advantage of this first approach is the simplicity of the
process. The disadvantage is the amount of manual procedures involved and
the fact that it can be time consuming.
2. Using the GIS functionality within the models. The advantage of the second
approach is GIS functions can be optimised to the exact needs of the models.
The undesirable effect is that GIS functionality is limited to the needs of
models and any extension can require programming efforts.
3. Using the models within the GIS. The advantage of this approach is that that
the resulting system is a general system. The disadvantage is the models data
and structures are dictated by the data and structures of the GIS (Karimi and
Blais 1997).
This study will employ the second approach and use the GIS functionality within the
models. Programming will be done with Model Builder as the advanced functions in
ArcGIS facilitate building spatial system models without combining different
programs.
In 2008 Lee, Huang and Chan inspired by Land-use and land-cover change (LUCC)
projects, examined complex land-use change systems and embarked on developing a
land-use change model. In the past various models have been created to simulate land-
use change, but no biophysical approach that can identify material and energy flows in
a land-use change system existed. In order to develop spatial system models that can
simulate land change, programming was needed to combine system dynamics with
Geographical Information System software. Therefore due to its difficulties in dealing
with spatial interactions and integrating different software programs, costs and the
fact that advanced programming skills were required. Spatial system models haven’t
Chapter 2: Environment Scan
Page 18
received much attention nor have they been applied widely. To overcome
methodological disadvantages of spatial system modelling Lee et al. (2008) study
presented a novel procedure that uses Geographical Information System (GIS) in
modelling a spatial system. To simulate land-use change, an example was utilized to
demonstrate the capabilities of Model Builder in GIS software.
The study explores the biophysical perspective of land-use change to identify material
and energy flows during land-use change. The study integrates different Spatial
Analyst functions into a spatial system model in Model Builder. Improvements for
spatial system models are developed to solve the problems associated with spatial
homogeneity and simplified spatial interactions. The proposed procedure, which
utilises Model Builder in ArcGIS, is presented and tested using a 10×10 cell space
with three scenarios to demonstrate the feasibility of the procedure and explanatory
power of the model. Model Builder in ArcGIS is an interface used to create models. It
is an object-oriented environment that formalizes procedures for processing GIS data
and other spatial analysis actions. The objectives of spatial system models are not to
develop spatial forecasting models but to design explanatory models for analysing
(Lee ,Huang and Chan 2008).
Model Builder will be investigated in this research and will be used to automate the
most frequently performed tasks by the Nature Refuge staff an example would be
providing a timely response to enquiries on Nature Refuge statistics from the Federal
and State Government. The answers provided are currently driving the decision
making processes within Nature Refuge Program. The models fast analysis capability
will facilitate solving simple or complex problems and enable to execute a series of
tasks more efficiently.
2.5 ENVIRONMENTAL MAPPING WITH GIS
In order to increase their abilities to analyse spatial data and link map variables with
appropriate management actions conservationists have been using spatial technologies
such as GPS, remote sensing and GIS. GPS receivers are used to establish positions
on the earth surface within a few meters or less. Geo-referenced remote sensing is
used to monitor landscape characteristics. Finally GIS is utilised to store attribute
Chapter 2: Environment Scan
Page 19
analyse and display that data (Berry et al. 2005). The following three reviews attempt
to support the hypothesis of this study.
Isaac et al. (2006) study predictive mapping of powerful owl breeding sites utilised
GIS to analyse ecological attributes present in current powerful owl (Ninox Strenua)
breeding sites. The methodology employed two study areas; the first consisted of
current breeding sites these were used to collect habitat characteristics data. The
second covered eastern part of Melbourne and was used to produce a predictive map
highlighting potential breeding sites and the species distribution. Within each breeding
site GPS was used to record locations for nest trees. The GIS overlay analysis was
performed on the eastern Melbourne study site using ecological characteristics
recognized at current breeding sites. Data layers from both sites were compiled using
ArcView as well as raw data layers of tree density, hydrology, ecological vegetation
classes, land use zones and slope data. To validate the reliability of the output
comparisons were made between historical records and the predictive mapping
results. Evaluation of this data indicated a significant relationship with 76% of
historical breeding sites located within the potential breeding sites predicted (Isaac et
al. 2008).
The Nature Refuge boundary information will be collected using the GPS and the
overlay analysis will be performed between the captured data and the Digital Cadastre
Data Base (DCDB) in order to validate existing surveyed boundaries but also to
construct new spatial boundaries of the protected area.
Fengri and Yinghui (2006) developed a multilevel GIS-based decision support system
of forest resource management for Shangzhi National Forestry Bureau, Heilongjiang
Province, China. The systems functionality included the analysis of forest resources by
area distribution eg. Dominant tree species, age and classes, or forest divisions
encompassing near-mature, mature and over-mature forest resources of commodity
forests. It was also useful for analysing spatial relationships between dominant species
and topographic variables as well as performing spatial searches for forest areas
suitable for regeneration, thinning or cutting. They used ArcInfo, ArcView, Geoway
3.0, ERDAS Imagine and R2V raster to vector software. Geographic data included
topographic maps forest inventory, sample plot data, forest types, TM images and
Chapter 2: Environment Scan
Page 20
GPS data. Processes included scanning, raster to vector conversions, creation of
digital topology, attributing data and structuring the spatial database. Display,
cartography, dual-comprehensive querying of spatial and attribute data, GPS
positioning, statistical analysis, updating resource data, etc were also some of the
many functions this GIS system provided to its users (Fengri and Yinghui 2006).
The GIS methodologies applied by Fengri and Yinghui will also be utilised in this
research. ArcInfo and ArcView will be used to compile Nature Refuge boundary
information. Processes such as scanning and raster to vector conversions will be used
to retrieve boundary information from hardcopy maps. Attributing the Nature Refuge
datasets will allow spatial and attribute queries to be performed. Finally a spatial
database will be created to leverage data relationships, enforce data integrity and
create intelligent features.
Laba et al. (2007) study involved mapping invasive wetland plants in the Hudson
River National Estuarine Research Reserve using QuickBird satellite imagery. The
National Estuarine Research Reserve (NERR) program tracks changes in ecological
resources of representative estuarine ecosystems and coastal watersheds. Utilising
high spatial resolution satellite imagery plant communities and invasive plants within
the Hudson River were mapped. The images were rectified and geo-referenced to the
Universal Transverse Mercator (UTM) coordinate system and the North American
Datum of 1983 (NAD83).The image processing component involved classification of
the imagery to distinguish areas of different dominant vegetation. Using the ERDAS
Imagine software package and a maximum-likelihood classification 20 land-cover
maps were produced. GPS was used to collect points along plot boundaries and data
concerning the immediate environment was collected and recorded. Onscreen
digitising was used to produce field plots of the GPS points and field data.
Conventional contingency tables and a fuzzy set analysis served as a basis for
accuracy assessments. The accuracy figures assessed by the contingency tables were
73.6%, 68.4%, 67.9% and 64.9%. Fuzzy assessment tables had even higher estimates
for map accuracies figures such as 83%, 75%, 76% and 76% suggesting that high-
resolution satellite imagery offers a huge prospective for mapping of invasive plant
species (Laba et al. 2007).
Chapter 2: Environment Scan
Page 21
DERM has a collection of recent cloud free geo-referenced and ortho-rectified
imagery, ranging from aerial photos to LANDSAT, SPOT QuickBird and IKONOS
satellite imagery. This imagery will be used as a base-map for onscreen digitising to
capture internal and external Nature Refuge boundaries where the area is not
accessible. The GPS will be used as the primary tool to capture field data.
2.6 GIS SUPPORTING MAJOR QUEENSLAND PROJECTS
GIS is used in a wide range of disciplines and organisations. In an organisation
whether it is the public or private sector GIS is best utilised if it is positioned as an
umbrella over the organisational multiple specialised disciplines (AECOM 2009). As it
can play a key role in asset management, infrastructure, engineering design,
environmental management, land management and natural resource management. GIS
connects these disciplines, departments and organisations. The ability to data-share
spatial data whether within a business or across multiple organisations has become
increasingly important and is a key factor in the successful implementation of a GIS.
In recent years there has been significant progress in sharing spatial data however
there still exists a level of hesitation. Harvey (2003) states that trust is the essential
ingredient in establishing partnerships and sharing data. Providing your data to other
organisations where you have limited or no influence can be an overwhelming task.
Some of the factors influencing the data sharing process are: who gets political and
financial control, managing updates to ensure accuracy, meeting requirements and the
provision of metadata (Harvey 2003).
There are many advantages of utilising GIS to assist in solving practical problems.
The advanced GIS capabilities are utilised in most of Queensland’s major
infrastructure projects. The data collection, data retrieval, analysis and reporting
functionalities allow the project teams to carry out the work in an innovative way. The
GIS desktop analysis capability has demonstrated to be an invaluable instrument in
achieving excellence in project management for environmental projects.
AECOM is one of the top three worldwide organisations specialising in environmental
design/engineering. The company undertakes a diverse range of large projects such as:
Chapter 2: Environment Scan
Page 22
Environmental Studies, Transportation Asset Management and Corridor Suitability
Analysis for Pipeline, Road, Electricity and Railway design. Environment Summary’s
(ES) and Construction Environmental Management Plans (CEMP) are prepared prior
to the works being carried out.
The purpose of the ES is to identify key environmental issues and their relevance to
proposed works. The purpose of the CEMP is to ensure that appropriate actions are
taken to mitigate the environmental issues identified in the ES. Extensive data
collection is required on environmental values. GIS desktop analysis and field
inspections are the backbone of these assessments. Spatial datasets such as Regional
Ecosystems, Biodiversity Planning Assessments, Koala habitat, Protected Area Estate
boundaries and Nature Refuge and Coordinated Conservation Areas are consulted.
Conclusions and recommendations are made on assumptions that the information
derived from these datasets is current and accurate. The GIS gazettal framework
developed by this study will ensure spatial data quality and integrity when
representing Queensland’s Nature Refuge boundaries. The Nature Refuge Branch will
gain the trust needed to share their data with other organisations.
GIS plays a fundamental role during the initial stages of projects. The Differential
Global Positioning System (DGPS) is used to collect field data. ArcGIS desktop is
utilised for analysis and provides an ongoing support tool during the project.
Additionally GIS is the main cartographic tool for the final presentation of high-
quality maps and charts. Spatial data is stored, organised and structured before the
initial analysis is performed. The native data structure for ArcGIS the geodatabase is
utilised as the primary format for spatial data storage and management. The advanced
functionality of the geodatabase allows additional manipulations of the data stored,
assisting the management team with further investigations and decision making
processes during the project.
The scope of GIS tasks commonly performed throughout a project:
Spatial data collection and coordination.
Spatial data transformations and coordinate conversions
GIS data capture

The GIS-based approach to these projects proved to be truly innovative, both in the
design, analysis and financial components (AECOM 2009).
2.7 CHAPTER SUMMARY
The chapter has presented the basic concepts of GIS and its origins; it offered a more
in depth look at the capabilities principles and structure of GIS. A variety of examples
dealing with environmental problem solving demonstrated the diversity of this
technology. The collection, analysis and storage of spatial information is essential to
any small or large scale engineering or environmental project. GIS is used in the
preliminary stages of a project, this can be in the form of producing a simple map
showing environmentally significant locations, or spatial analysis to show
relationships, site and route suitability and change detection. It is at this stage the
spatial quality and integrity of the Nature Refuge boundaries is tested. They are
overlayed with a variety of spatial data and recommendations are made on
assumptions that the dataset is current and accurate.
This chapter has revealed that GIS technology is exceptionally capable of providing
assistance in the decision making process of a variety of fields across an organisation.
GIS can amalgamate data and provide decision makers with a powerful tool to collect
knowledge on disciplines as diverse as ecology, infrastructure, planning transportation
utilities and many more. When utilised as one, it contains the key elements to support
action. Within this context the following chapters will give a concise presentation
aimed at testing the hypothesis:
GIS can streamline the gazettal process and improve the spatial integrity and
quality of Nature Refuge boundaries.
Chapter 3: Spatial Choreography

“Imagine what it would be like when trying to find something in the
libraries and databases of the world, where organisation was done by someone
else who had no idea of what my needs were. Chaos, Sheer chaos” (Norman
1988 pg.215)
This research is about developing a GIS gazettal framework to streamline the Nature
Refuge gazettal process. The framework encompasses a number of interrelated
phases. Figure 3-1 illustrates the fundamental steps to be undertaken in order to
accomplish the aim of this research. Chapter 3 develops the framework, addresses
issues such as data collection and proposes improvements to the current method used
for collecting boundary information. The focus will be on survey quality techniques
such as the DGPS to capture boundary information. The chapter then deals with the
map presentation issues. Map clarity problems have been addressed by creating a
visually balanced and easy to read protected area plan, as discussed in the previous
chapter the cartographic quality is essential for the maps validity. Map features that
are difficult to read can be easily misinterpreted as the maps core value lies in its
graphical presentation of information (Jones and Greven 2004).
The latter part of the chapter will focus on constructing spatially accurate Nature
Refuge datasets. The aim of Chapter 3 is to achieve the following research objective:
Investigate and utilise GIS and its advanced functionalities to enhance the
mapping component of the Nature Refuge Program.

3.1.2 Employing Survey Quality Collection Techniques
When utilising the Global Positioning System (GPS), information is received from
satellites orbiting the earth. The GPS is a satellite based navigation system used for
civilian navigation and positioning, surveying and scientific applications.
It is one of the most accurate tools used for mapping. Figure 3-2 illustrates the
Trimble GPS unit, these units are specifically designed to collect and store spatial
information. Data collected with Trimble units and differentially corrected under
normal conditions will yield an accuracy confidence ranging from sub-meter to five
meters. On the other hand Garmin units are primarily designed as navigation tools.
The Handheld Garmin units that are currently used to collect boundary information do
not have post-processing differential correction capability. However many receivers
have the capability to use Differential Global Positioning System DGPS and Wide
Area Augmentation System WAAS. It is important to have the unit set correctly in
order to obtain quality data. Also, higher-end models tend to have the technology of
increased filter capabilities that will provide for an even better GPS/GIS output. Poor
data collection techniques and errors like multipath can increase the need for editing
the collected data if it is to be used in GIS correctly (Roper 2006).
Chapter 3: Spatial Choreography
Page 27
Figure 3-2 Trimble Nomad
To improve the accuracy of positions obtained from GPS, differential corrections can
be applied to the observed position at a remote site. These corrections are calculated
at one or more base stations by comparing the observed position with the known
position. The base stations may be a permanent service, or be setup specifically for a
project. When applied at the remote site these corrections greatly enhance the
positional accuracy. The correction can be in terms of position, or more often in terms
of the observed satellite-receiver distance (the pseudo-range). The corrections may be
collected and applied at a later time, or they may be broadcast immediately to the
remote site by mobile phone, radio or satellite communications. Two commonly used
formats for this type of differential correction are the NMEA and RTCM formats.
DGPS positioning can be carried out with some simple hand held receivers over a few
10s of kilometres, or it may be done with sophisticated multi-base-station systems
integrated with satellite communications, to cover a region of thousands of kilometres
(wide area differential navigation). The accuracy of DGPS, of the order of a metre,
generally degrades with increased distance from the nearest base station (GeoScience
Australia 2005). DGPS is the method of improving positional accuracy of a GPS
Chapter 3: Spatial Choreography
Page 28
location, by applying corrections from a known position or base station. The
corrections applied, remove the effects of atmospheric errors, timing errors and
satellite orbit errors.
The Hemisphere R130 antenna and decoder is what allows the system to work at 50 -
70cm accuracies in real-time. This is called the VBS system (Virtual Base Station).
The OmniSTAR DGPS VBS is a satellite based differential signal that is accessed
through an annual subscription. It is consistent real-time sub-metre accuracy with
world coverage 24hrs a day. The OmniSTAR VBS technology uses all reference
stations in the vicinity of the receiver and computes a set of enhanced RTCM
corrections for the user’s position. In this way, the user is provided with corrections
without the need to manually select a reference station and is protected from the
failure of any single reference station (GeoScience Australia 2005).
3.1.3 Mobile Mapping and GIS
ArcPad is the world’s main GIS software package used for mobile mapping (ESRI
2002). It provides field personnel with the ability to capture, analyse and display
geographic data. Field mapping with ArcPad is efficient and accurate it incorporates
data input from GPS receivers with data directly from an organization’s GIS system.
The captured data can easily be downloaded to ArcGIS for further processing. It is
easy to use and affordable. An extensive array of ArcGIS symbols are supported in
ArcPad. Figure 3-3 illustrates the resemblances of the ArcPad interface to ArcGIS
this enables maps in ArcPad to mirror the appearance of those in ArcGIS. Therefore
using familiar symbology, which complies with organizational standards, makes it
easier for field personnel to use mobile devices loaded with ArcPad when collecting
data (ESRI 2002).

3.2 DESIGNING NATURE REFUGE PLANS IN GIS
Analytical Cartography has been around since the late 1960’s. Professor Waldo
Tobler is widely considered as the father of Analytical Cartography a course taught by
him as part of the geography program at the University of Michigan. The core
principles of Analytical Cartography are the creation of maps that can be easily
explored, interpreted and analysed (Tobler 1976).
Appropriate cartographic communication is essential for the map to be understood.
When designing the Protected Area Plan the author’s intention was to fulfil the
following map objectives:
Design a truthful representation of reality
Interpret the raw data accurately
Select clear symbology
Seek new software techniques to assist the map reading process.
Create a useful, visually balanced and easy to understand map product. (ESRI
2004a).
Chapter 3: Spatial Choreography
Page 30
3.2.1 The Map Template
The map design consists of devising a balanced and effective set of cartographic
elements. The GIS makes this technique possible by supplying tools to generate
modify and rebuild the map (Clarke 1999). Geographic Information and maps are
ways of making people understand. Both communicate in different ways and at
different levels to a diverse audience influencing what people know. The essential
element of most maps is colour when applied properly it serves as a powerful
communication tool (Harvey 2008). Colour is fundamental to the Nature Refuge
Plans as it highlights the boundary and effectively communicates different zones
within the protected area. A quick way of creating a new map is using a template.
Figure 3-4 represents the Nature Refuge template developed by this study, portrayed
as a map document it has a custom interface and a predefined layout that arranges
elements such as logos, legends, north arrows and scale bars on the virtual page.
Templates are essential to the Nature Refuge Mapping Program as many maps with
the same design need to be created. The template created specifies the standard plan
size, styles, font, title block, line, shading, borders and layout (ESRI 2004a).
Chapter 3: Spatial Choreography
Page 31
Figure 3-4 The Nature Refuge Map Template
Chapter 3: Spatial Choreography
Page 32
3.2.2 Symbology
Styles are an organised collection of elements used to create maps. Styles incorporate
elements such as symbols, scale bars, north arrows, colours and patterns providing
information on:
Symbol properties
Labels specifications
Colour schemes
Legend and scale bar characteristics
Coordinate and reference systems (ESRI 2004a).
Styles are a powerful tool they not only define how data is drawn but also provide
storage for map elements. To promote consistency in the Nature Refuge Mapping
Program style manager was used to configure custom styles for the Nature Refuge
Protected Area Plans.
Figure 3-5 illustrates the custom styles developed by the author. The Nature Refuge
boundary, the DCDB parcels and internal zone patterns were all symbolized in order
to accelerate the mapping component of the protected area plan production. The
symbol sets have been grouped into the Protected Area Nature Refuge (PANR.style)
palette under the PA Plan Symbols. Colour is very important as it can greatly affect
the interpretation of a plan. Standard colours for representing Nature Refuge
boundaries have been selected by the author and approved by the Nature Refuge
Branch. Olivenite Green represents the Gazetted Nature Refuges of Queensland,
Electron Gold is the colour for the Proposed Nature Refuge boundaries and Rose
Quartz stands for the Potential Nature Refuge boundaries. The colour selection has
been chosen intentionally to reflect the working stages of these properties by
portraying them to replicate the functions of traffic signals.

3.2.3 Map Quality Standards
The following cartographic standards are used by this study for the map presentation
of Nature Refuge Protected Area plans.
All items on the Nature Refuge Protected Area plan to be shown using the
standard colours and line styles and symbols developed by this study. Styles
are stored in the following style file PANR.style. Standard text styles must
also be used – these are listed in Appendix 2.
The subject parcel/s must be identified with a lot identifier in accordance with
the QSIC Parcel Identification Standard. The subject area must be shown in
bold and with slightly larger text than adjoining lots. Where space does not
Chapter 3: Spatial Choreography
Page 34
permit the identification of a parcel, the text may be placed outside the parcel,
and indicated with a solid black arrow.
Where the Proposed Nature Refuge covers all of an existing or proposed lot
on plan with no exclusion zones the existing lot on plan should be used to
define the boundary using the standard PANR.style.
Where the Nature Refuge covers part of a lot on plan and the remainder is
excluded use the cadastral boundaries where possible. The whole exclusion
area must be clearly defined by one seamless boundary outline. Any internal
boundaries that are within the exclusion area must be shown using the DCDB
standard line style.
Where the Nature Refuge encompasses multiple lots the whole subject area
must be clearly defined by one seamless boundary outline. Internal nature
refuge boundaries must not be highlighted and are to be shown using the
DCDB standard line styles.
The parcels that are the subject of the plan must show an area. Where the
Nature Refuge area is a part of parcel/s, or is a whole of parcel that has not
been surveyed, the area must be shown to the nearest hectare. Where the
Nature Refuge area is a whole of parcel, and the parcel has been surveyed, the
area shown must be the surveyed area. The area must be shown on the face of
the plan, inside the boundary concerned. Where space does not permit the
total area to be shown inside a parcel, the total may be shown by statement.
e.g. “Total Area Lot XX Abt 3.222ha”
Adjoining lots should be shown and identified in accordance with the QSIC
Parcel Identification Standard. Where an existing Protected Area is shown, it
must be labelled with its gazetted name. An adjoining Gazetted Nature Refuge
property must be shown using the appropriate style created in PANR.style.
The plan must clearly identify the source of the information used in preparing
the plan for example topographic maps, aerial photography, the DCDB,
sketches, GPS points. The date and/or version must also be shown.
A table of reference points must be shown if these were used to construct the
boundary. For points derived by GPS equipment, the table should be headed
“GPS Reference Points”. The datum/projection used on the GPS unit for data
Chapter 3: Spatial Choreography
Page 35
collection should be stated. Where reference points have been generated from
a GIS the table should be headed “Derived Reference Points for GPS”. Where
reference points are generated, ground truthing is required.
GPS points should be displayed to the accuracy of capture. If ground truthing
has not occurred, GPS points can only be displayed to the accuracy of the
base data.
The following note must accompany a table of reference points: “Note: GPS
control points are to be used for the location of internal boundaries only.
Responsibility for locating these boundary lies solely with the landholder.”

3.2.4 File Naming and Folder Structure
There is a vast amount of GIS files required in compiling data to support a variety of
mapping and analysis tasks for a single Nature Refuge property. As GIS can use an
immense amount of drive space for the continual number of files archived. It is vital
to think systematically about how data is to be stored, updated and accessed.
Appendix A3 and A4 contain the Nature Refuge file naming and folder structure
standards. A cohesive compilation approach has been adopted to structure spatial data
into base folders; these folders provide a predictable means of understanding where
collected data should be stored.
3.3 CREATION OF NATURE REFUGE SPATIAL DATASETS
In GIS, the geographic data is in the form of layers. Figure 3-6 illustrates the concept
of a GIS which is overlaying a number of data layers to relate variables at the same
geographic location. The GPS collected point boundary data is overlayed with the
Nature Refuge polygons, these polygons have been created from the GPS collected
points and the existing boundaries of the DCDB. Other layers include the Protected
Area Estate boundaries, the DCDB and raster layers such as Scanned Maps Satellite
Imagery and Digital Elevation Models (DEM). The layers can be overlaid; they can be
visually and mathematically correlated or interpreted. Each map layer is used to
Chapter 3: Spatial Choreography
Page 36
display and work with a specific GIS dataset. Layers with complete coverage of the
area, such as filled polygons or a raster, are usually drawn underneath other map
layers (ESRI 2004b).
Figure 3-6 The Concept of Layers
Layers can be saved, shared and reused without sharing the entire map. When the
layer is added to another map, it will draw exactly as it was saved. Additionally, the
orders of layers in the table of contents (ArcMap) determine the drawing order of
layers. The map layers placed higher in the table of contents are drawn on top of those
that are lower, the order can be easily changed (ESRI 2004b).
A feature class represents a collection of features portraying the same geographic
elements such as parcels. They share a common set of descriptive attributes (Arctur
and Zeiler 2004).
Chapter 3: Spatial Choreography
Page 37
In the GIS and mapping component of the Nature Refuge Program the following
collection of feature classes are identified to represent the Nature Refuge boundaries.
Figure 3-7 illustrates the distribution of Nature Refuge boundaries throughout
Queensland. These feature classes will be used for analysis and provide visual
evidence on the extent and location of Nature Refuge properties for landholders,
program managers and policy makers.
Historic Nature Refuge dataset - acts as a repository for Nature Refuges which
have not progressed through to gazettal for a variety of reasons.
Gazetted Nature Refuge dataset - depicts a portion of land which may be a whole
of lot or a partial lot, with or without internal zones, which has been accepted through
the Nature Refuge Program, executed by the landholder and either the Director
General of DERM or the Minister of Environment and Resource Management to
protect areas of land with high environmental value in perpetuity.
Future Nature Refuge datasets – represents the working stage or development of
Nature Refuges these properties which are in the preparation stage for submission
into the Nature Refuge Program via the Nature Assist tenders these properties are
recognised for having particularly high environmental values.

3.3.1 The Diversity of Zones within a Nature Refuge
A Nature Refuge Agreement outlines activities that can occur on the Nature Refuge
property these are referred to as Zones. The agreement incorporates activities ranging
from grazing to recreation the activities are managed in a sustainable manner and are
appropriate for the level of protection required. Currently there is no national data
management system to capture covenanting information enabling policy makers and
interested agencies to know where land is covenanted and what biodiversity values
are being protected or managed.
The different zone types within a Nature Refuge boundary were not considered when
exporting boundary information from CAD. They are referred to in the Conservation
Agreement and exist visually on hardcopy maps but are not in digital form. On the
maps, zones have no standard classifications; for example an internal zone boundary
within one Nature Refuge dedicated to grazing purposes would be labelled Zone 1.
Then on another Nature Refuge, the Zone 1 label would be used for a boundary
dedicated to domestic purposes. The ability to have these boundaries in a GIS
environment is invaluable for consistency. Analysis and monitoring can be performed
to ensure restrictions agreed to in the Conservation Agreement regarding land uses
and land management activities are adhered to by the landowners. The following
outlines the different types of Nature Refuge Zones and the land management
activities occurring within them.
Domestic Zone – Land uses and land management activities conducted in the
Domestic Zone, as described in the Protected Area Plan, will not adversely impact on
natural and cultural resources on the land by:
Constructing and maintaining a single dwelling including access track and
ancillary infrastructure.
Constructing renewable energy infrastructure on the land for domestic power
supply only.
Restricting the introduction of native plant species that are not locally endemic
to non-invasive species.
Restricting the introduction of non-native plant species in the domestic zone to
lawn, fruit trees and vegetable plants.
Chapter 3: Spatial Choreography
Page 40
Relocatable Domestic Zone - Land uses and land management activities conducted
in the Relocatable Domestic Zone, as described in the Protected Area Plan, will not
adversely impact on natural and cultural resources on the land by:
Restricting the introduction of native plant species that are not locally endemic
to non-invasive species.
Restricting the introduction of non-native plant species in the domestic zone to
lawn, fruit trees and vegetable plants.
Infrastructure Zone - Land uses and land management activities conducted in the
Infrastructure Zone, as described in the Protected Area Plan, will not adversely impact
on natural and cultural resources on the land by:
Ensuring the Infrastructure Zone does not exceed maximum of 10 hectares
Restricting visitor infrastructure (cabins and communal areas)
Constructing renewable energy infrastructure on the land.
Installing water supply infrastructure, including pumping equipment and a
supply line, on the land for domestic water supply only.
Relocatable Infrastructure Zone - Land uses and land management activities
conducted in the Infrastructure Zone, as described in the Protected Area Plan, will not
adversely impact on natural and cultural resources on the land by:
Ensuring the Relocatable Infrastructure Zone does not exceed maximum of
1hectares
Restoration Zone - Land uses and land management activities conducted in the
Infrastructure Zone, as described in the Protected Area Plan, will not adversely impact
on natural and cultural resources on the land by:
Restrictions are imposed and agreed on case by case basis.
Agricultural Zone - Land uses and land management activities conducted in the
Infrastructure Zone, as described in the Protected Area Plan, will not adversely impact
on natural and cultural resources on the land by:
Restrictions are imposed and agreed on a case by case basis (DERM 2008).
Chapter 3: Spatial Choreography
Page 41
Diverse styles depicting different internal boundaries have been created in style
manager for each of the zones. Zone classifications were developed as part of this
research to avoid issues relating to the conflicting identification of internal boundaries.
Table 3.1 Internal Zones Attribute Categorization
There is an assorted quantity of restrictions tied to each zone. The proposal by this
study is to capture and store internal zone information as per the methods used for the
presentation of Nature Refuge external boundaries. This means GPS collected internal
boundaries. At the initial stage of preparing a Protected Area plan each zone is to be
captured, classified as per Table 3.1 and stored as an individual shapefile within the
Nature Refuge folder. Appendix 4 contains the zone file naming conventions. Finally
all zones in every Nature Refuge to be presented as one feature class in preparation
for analysis. The ability to have this information in a GIS is imperative as it will enable
biodiversity to be considered at the start of the planning process.
3.3.2 Building the Nature Refuge Spatial Dataset
To facilitate the design of a comprehensive, accurate and current spatial layer the
boundaries of all Queensland’s Gazetted Nature Refuges needed to be incorporated
into the GIS. The boundary data required dated back to 1994 and Berlin Scrub the
first Nature Refuge gazetted.
There were three categories of information available:
Category 1 - Hard copy maps
Tenure and Zoning Classification
Domestic Zone A
Relocatable Domestic Zone AR
Infrastructure Zone B
Relocatable Infrastructure Zone BR
Restoration Zone C
Agricultural Zone D
Chapter 3: Spatial Choreography
Page 42
Category 2 – CAD files (one dxf file for each individual boundary)
Category 3 - The first batch of gazettal produced in GIS by the author June 2005
Initially scanning, geo-referencing and on-screen digitising was used to bring the
information into GIS but eventually a more efficient way to streamline this integration
was required. ArcScan was then investigated and exploited for the conversion of non-
spatial data to GIS. ArcScan is an ESRI extension used primarily for organisations
that need to convert raster images into vector feature layers. The various tools within
ArcScan have been tested and an accurate boundary representation was derived using
either the centreline and/or outline the two types of vectorization methods available in
this extension.
3.3.3 Standardizing the Gazetted Nature Refuge GIS Dataset
Key issues for spatial data users is finding and evaluating spatial data. How this data is
organised labelled and described is fundamental to its successful evaluation and
utilization.
In order to integrate the Nature Refuge boundaries and prepare them for publishing internallyand externally the layers tabular information was richly and consistently attributed. This
enables the attributes to be used for analysis purposes, and feature selections to be done basedon the attributes (e.g. select all nature refuges gazetted in 2002). Attribute fields were
populated with information relating to the Nature Refuge’s such as gazetted date, gazettedarea, lot/plan information, tenure, IUCN number and so on. A fundamental attribute value
was also incorporated into the layer; the System Integration Code (SYSINTCODE).
Figure 3-8 shows the National Parks also contain a SYSTINCODE this is the unique
identifier linking DERM’s core business datasets.
Chapter 3: Spatial Choreography
Page 43
Figure 3-8 The System Integration Code (DERM 2005)
In cases where data was available in digital format the process was automated using
several ArcGIS functions. Spatial join was one used to retrieve attributes from the
DCDB, Queensland Parks and Wildlife Regional Boundaries (QPW), Local
Government Boundaries (LGA). The decimal degrees x, y coordinates, depicting the
Nature Refuge centroid were automatically generated using the X-Tools Pro
extension software.
Once the Gazetted Nature Refuge Dataset was finalised within the GIS environment a
quality assurance process was carried out by cross- referencing the attribute data to
different sources. In this case prior knowledge on the data sources with a higher level
of reliability was required. Sources used for the comparison were Estate Register,
Government Gazette, Conservation Agreement and the official PA plan hardcopy.
This process highlighted inconsistencies such as area miscalculations, incorrect
naming of the Nature Refuges and other anomalies in both the Estate Register and
Government Gazette. These irregularities were then addressed through the Minister’s
Executive Council Briefing Note and amended by the Nature Conservation (Protected
Areas) Amendment Regulation.

3.3.4 Metadata
Described as ‘data about data’ or data that makes data useful. Metadata provides
records that can support search, directions needed to open and use datasets, and
information essential to assess the data set’s appropriateness for a specific application
(Goodchild 2002).
It documents a dataset’s key statistics and how it can be accessed and exchanged.
Spatial data without metadata can be worthless and carries a risk of data misuse. This
can lead to errors in data analysis. Metadata equips data custodians with better
knowledge of their data allowing them to more effectively manage data production,
storage, maintenance, update, and reuse. A good GIS system should support three
forms of metadata the implementation form (within a database or software system),
the export or encoding format and the presentation or viewing form (Hunter and
Masters 2003; Miller ,Karimi and Feuchtwanger 1989).
The Federal Geographic Data Committee (FGDC) Standards assist the development,
sharing, and use of geospatial data. The FGDC develops geospatial data standards
for implementing the National Spatial Data Infrastructure (NSDI) in consultation and
cooperation with State, local, and tribal governments, the private sector and academic
community. A metadata record is a file of information, which captures the basic
characteristics of a data or information. A geospatial metadata record includes a title,
abstract publication date, geographic elements, geographic extent, projection
information and database elements (FGDC 1994).
Australia and New Zealand Land Information Council (ANZLIC) is the leading
agency in Australia and New Zealand for providing standards and facilitating access to
data and services within the spatial industry. As an intergovernmental organization,
ANZLIC also provides leadership in the collection, management and use of spatial
information in Australia and New Zealand. ANZLIC metadata shares similarities with
the FGDC CSDGM and International Organization of Standardisation (ISO) metadata
standards for geographic information (i.e. ISO 19115), as these two standards have
had a strong influence on the development of the ANZLIC Guidelines (ANZLIC
2001).
Chapter 3: Spatial Choreography
Page 47
Figure 3-9 Metadata Standards for Gazetted Nature Refuges
Data documentation or metadata gives the user an insight into the datasets
compilation. The Nature Refuge Branch is now the data custodians of several spatial
datasets, offering them to other organizations for data sharing purposes therefore they
have an obligation to provide up to date, accurate and efficient data. The Gazetted
and Proposed datasets were provided with the FGDC metadata standards Figure 3-9
illustrates the metadata standards for Nature Refuges gazetted up to June 2009. The
FGDC metadata standards are used in DERM by data custodians as it is embedded in
the ArcGIS software being utilised to create the data. However when publishing the
datasets as a spatial product the ANZLIC compliant fields are extracted and data is
provided to the ANZLIC standards.
3.3.5 Potential and Proposed Nature Refuge Datasets
Nature-Assist is the incentive component of Queensland’s Nature Refuge Program.
Nature-Assist provides financial assistance for landholders who actively manage the
natural and/ or cultural assets of their property. Having an accurate and up-to-date
Gazetted Nature Refuge layer available, awareness was raised of the GIS capabilities
and its benefits to the decision making process. As a direct result the need for a
Potential and Proposed NR layer arose. The Potential and Proposed datasets were
created in a spatial context using the same process and principles applied in the
Chapter 3: Spatial Choreography
Page 48
making of the Gazetted Nature Refuge layer. This in turn enabled the Nature Refuge
Branch to spatially monitor the progress and development of a Nature Refuge. The
Potential dataset reflects the first stage of tendering so as the negotiations for a
Nature Refuge progress with the development of the Conservation Agreement, the
properties advance to the second stage hence the development of the Proposed
Nature Refuge layer. The Potential layer is currently available only within the Nature
Refuge Branch and is used for decision making purposes. The Proposed layer on the
other hand is available internally within the public sector. The Proposed layer operates
as an alert mechanism and is provided to the mining sector, developers and Local
Government. It is used to detect conflict of interest in the case of multiple applications
from landowners applying for semi-government funding. The Proposed layer appears
on the DERM internal web mapping system ECOMAPS. Confidentiality issues have
been addressed by concealing attribute fields containing landowner’s details prior to
the publishing process.
In addition to the above datasets the Historic Nature Refuge spatial dataset was
created. This dataset provides an easily accessible storage to enhance future planning
and financial support for the program. The Historic dataset serves as a repository for
Nature Refuges which have not progressed through to gazettal for a variety of
reasons:
Disagreement on boundaries, zones or Conservation Agreement restrictions
Time delays
Sale of property
Ownership disputes
Tenure changes
Non acceptance into a Nature Assist tender round
Chapter 3: Spatial Choreography
Page 49
3.4 CHAPTER SUMMARY
Chapter 3 developed the first phases of the GIS gazettal framework, with each phase
positioning the Nature Refuge boundaries closer to achieving spatial quality and
integrity. Global Positioning System (GPS), mobile devices, and GIS software are the
three technologies when integrated together facilitate the collection, creation and
analysis of Nature Refuge boundaries allowing field and office based personnel such
as the Nature Refuge Officers to perform tasks in a timely manner.
In addition the chapter goes behind the “map” scene and enlightens this hidden
environment. This is a very significant part of map presentation as the map output
does not automatically portray the entire background mechanism activating it. The
various layers, databases, themes, elements, attribute and metadata are often not
thought of when viewing a “pretty” map. For this reason the second part of the
chapter focused on this very important part of the map. Cartography is an integral
part of GIS and the design of a map is a complex process (ESRI 2004a). GIS users
may be highly skilled in performing spatial analysis but if they don’t know how to
effectively communicate those results through map presentation they risk producing
dangerously misleading maps.
Chapter 4: Data Integrity and Analysis
Page 50
4Chapter 4: Data Integrity and Analysis
“Unlike maps, the purpose of GIS is to maintain geographic data in a state(s)
that may be transformed, processed, and analysed in ways that are
geographically uniform”(Goodchild ,Wright and Proctor 1997)
This chapter investigates and examines issues such as uncertainties in topological
relations caused by spatial inaccuracies. Phases 4 and 5 of the GIS gazettal framework
are developed demonstrating the importance of taking a spatial perspective when
representing the protected area boundaries. The data collection and preparation has
been discussed in Chapter 3, the next step is to ensure the integrity of these spatial
boundaries in preparation for analysis by utilising the functionalities of the
geodatabase model. A number of spatial queries will also be presented as the chapter
then moves into spatial modelling one of the hottest research topics in the GIS circle.
The aim of Chapter 4 is to achieve the following objectives:
Develop a digital database that places Queensland’s Nature Refuge
boundaries in a spatial environment that facilitates analysis and effective spatial
data interchange between the States/Territories and the Commonwealth.
Evaluate the framework through meaningful analysis
4.1 BUILDING THE GEODATABASE
The geodatabase combines the properties of objects with their behaviours. Object-
oriented data models portray the organisations own view of the real world. These data
models are therefore intuitive and simple to use. A GIS will deal with user-oriented
concepts like cadastral parcels and drainage basins in addition to system-oriented
concepts like points, lines, and polygons. The model allows the user to define
relationships between objects. The model also sets rules for maintaining the referential
integrity between objects such as topology of spatial data, spatial features and
Chapter 4: Data Integrity and Analysis
Page 51
attributes, basic rules, administration restrictions and legal limitations. The user’s
ability to define their own object-oriented feature classes makes GIS contain human
knowledge closer to reality than before (Chen 2008).
Due to the lack of coordination between GIS personnel within DERM, geographic
data is fragmented between different administrative boundary systems. Current
technologies for analysing spatial data such as GIS cannot thus provide accurate
results. A good example of the problem would be the DCDB of Queensland and the
Nature Refuge GIS dataset, where two individual agencies have established
independent sets of boundaries. The Nature Refuge boundaries are based on the
DCDB therefore the frequent updates to the DCDB results in additional manipulation
of the Nature Refuge dataset.
Figure 4-1 depicts an example of alignment inaccuracies between the DCDB and
Nature Refuge dataset. This issue will be addressed by structuring the data into a
geodatabase and enforcing the boundaries to participate in topology. The ability to
model spatial relationships using topology is a key GIS capability (Arctur and Zeiler
2004).

The File Geodatabase is implemented as a collection of binary files in a file system. It
has no size capacity limit. By default, each table can store up to 1 terabyte of data.
Vector data stored within the file geodatabase can optionally be compressed into a
read-only format, reducing the memory footprint and improving performance. Users
can uncompress the vector data to make it editable at any time. It is also possible to
have more than one editor in the file geodatabase at the same time, provided they are
editing in different tables, feature classes, or feature datasets (ESRI 2006). Figure 4-2
illustrates the Nature Refuge Geodatabase model designed by the author. The model
consists of elements such as feature classes, subtypes, feature datasets, topology and
relationship classes.

4.1.1 The Geodatabase Structure
The advantages of storing feature classes within a feature dataset is that geospatial
relationships can be modelled between the feature classes, enabling more advanced
GIS analysis. To ensure data integrity and address the alignment inaccuracies between
the DCDB, Nature Refuge boundaries and DERM’s Estate boundaries, the data was
organized into feature classes/feature datasets within a file geodatabase. Topology
was introduced to manage the spatial relationships between features classes in the
feature dataset. The geodatabase supports an approach to modelling spatial objects by
incorporating their behaviour while supporting different types of key relationships
between them. A collection of rules and relationships were applied to the datasets as
this will assist to more accurately model their geometric relationships (Arctur and
Zeiler 2004).
The following geodatabase elements were used in the design of the Nature Refuge
Geodatabase as per Figure 4-2. Supplementary datasets such as the Remnant,
Regrowth Biodiversity Planning Assessments etc. were included in the geodatabase
structure at this stage to allow for future modelling of Nature Refuges and these
datasets.

Subtypes:
Subtypes are used as a method to categorize spatial data. They are a subset of
features in a feature class, or objects in a table, that share the same attributes (ESRI
2006). Subtypes organise the data in a way that maintains the integrity and efficiency
of features during editing and are essential to good design as they reduce the number
of feature classes (Arctur and Zeiler 2004). Table 4.1 illustrates the subtypes created
for the NAME attribute field of the Gazetted Nature Refuge feature class. The coded
values in the NAME field differentiate Nature Refuges that cover the whole of lot on
plan, or part of the lot on plan, Nature Refuges not funded by Nature Assist and
properties that have received the Nature Assistance funds.

Topology:
Topology in maps describes spatial relationships such as adjacency, coincidence,
connectivity and containment of the mapped features. Topology offers special
functions for spatial analysis and is one of the most useful data structure concepts in
GIS. Geodatabase topology accurately models geometric relationships between the
features it knows where it is, what is around it, recognizes the surrounds and finally
knows how to get around (ESRI 2004b).
The topology within the Nature Refuge Geodatabase will manage coincident
geometry it will constrain how the Nature Refuge boundaries share geometry with the
DCDB and Estate boundaries it will define and enforce data integrity rules.
Figure 4-3 shows one of the behaviors that will be enforced to ensure no polygon
overlaps another polygon in the same feature class.
Figure 4-3 Topology Rule - Must Not Overlap
Topology supports powerful editing tools that implement the topological constraints
of the data model. An example of this would be the Nature Refuge boundary shares a
common edge with the DCDB and the Estate boundaries so when a Nature Refuge
boundary is updated all the features that share that common edge will automatically
be updated. In a geodatabase topology, one of the integrity rules that can be set is a
coordinate rank. This determines which feature classes have the highest level of
accuracy. Ranks control how vertices move during validation. Lower ranked features
(50) will be adjusted to the higher ranked features (1) (Arctur and Zeiler 2004).
Chapter 4: Data Integrity and Analysis
Page 57
The Parcels_topology stored in the Nature Refuge Geodatabase defines and enforces
data integrity rules for the features. Groups of properties stored include cluster
tolerance, ranks and rules. For example, there should be no gaps between the
polygons is one rule that is used to define spatial relationships between the features.
Topology supports topological relationship queries and navigation, such as feature
adjacency, connectivity and coincidence (ESRI 2008). The geodatabase topology was
used to group the DCDB and Nature Refuge feature classes together. Figure 4-4
depicts the set of rules used to define the features behaviour. Topology ranks were
also set as they enable a finer control over which features will be moved in the process
of snapping vertices so each feature was assigned a rank. The Nature Refuge
boundaries are based on the lot on plan of the DCDB parcels therefore the DCDB
parcels were given the highest ranking of 1 so that during the validation process the
Nature Refuge boundaries move to the DCDB vertices.
Figure 4-4 Set Rules for the Parcels Topology
Chapter 4: Data Integrity and Analysis
Page 58
Relationship Classes:
A relationship class is another geodatabase element used in the structure of the Nature
Refuge Geodatabase. Relationship classes provide a mechanism for referential
integrity. A persistent feature class to feature class link was created between the
records in the origin (Nature Refuge Gazetted) table to the destination (Nature
Refuges Internal Zones) table.
4.2 SPATIAL ANALYSIS AND GEOPROCESSING
Analysis is a process for highlighting patterns and relationships in geographic data.
Even though GIS technology has been around since the 1960’s many people still use
it solely for mapmaking purposes (ESRI 2004b). The spatial analysis function consists
of three basic types of operations: attribute queries, spatial queries and generation of
new datasets based on data attributes or spatial relationships. Operations range from
simple to complex queries. A single attribute or spatial query falls into the simple
category. A complex analysis requires a series of operations that include multiple
attribute and spatial queries adjustments of original data and generating new datasets
based on attribute information or spatial relationships and sometimes both (ESRI
2005). The first four phases of the GIS gazettal framework have addressed issues
such as quality data collection techniques, constructing Nature Refuge boundary
information, generating new spatial datasets and ensuring the integrity of these. The
final phase of the research design will demonstrate the advanced capabilities of GIS
available to the Nature Refuge Branch.
4.2.1 Testing the Research Design
Geographic information querying involves both the spatial and attributes aspect. The
next part of the chapter will examine spatial queries starting with some basic examples
and ending with a complex query that requires spatial analysis before the question can
be answered. Naturally these examples do not reveal the full range of GIS operations
that are available. However within the confines of this chapter and following the five
steps of the analytical process discussed in (Chapter 2, Fig. 2-1)
Chapter 4: Data Integrity and Analysis
Page 59
The subsequent four simple and complex queries are selected to demonstrate the
accessible analysis opportunities.
Query 1 Relates to an enquiry about the current statistics of Gazetted Nature
Refuges in Queensland the query was required for reporting purposes.
Question: How many Gazetted Nature Refuges in Queensland?
Data: Dataset required for analysis is the Gazetted Nature Refuge dataset
Method: Attribute Query is selected to answer this question as the attributes
required are available on an independent table. Therefore no relationship class
or data join is required.
Process: Figure 4-5 illustrates the process of creating a new selection to
answer this query. Records are selected from the Nature_Refuges_Gazetted
layer, based on the NAME_COUNT field where the unique value is 1.
Figure 4-5 Query 1 Process
Chapter 4: Data Integrity and Analysis
Page 60
Query 2 - Identifying spatial inconsistencies between the Protected Area Estate
dataset and the Nature Refuge dataset.
Question: How many Nature Refuge boundaries overlap the Estate boundaries?
Data: Datasets required for analysis is the Gazetted Nature Refuge dataset and the
Protected Area Estate layer
Method: The question relates to spatial relationships among the features of interest
Spatial Query is selected to provide the answer.
Process: Figure 4-6 shows the select by location query selected to answer the
question. Only features from the Nature_Refuge_Gazetted layer that are crossed by
the outline of the Protected Areas of Queensland layer will be selected.
Figure 4-6 Query 2 Process
Chapter 4: Data Integrity and Analysis
Page 61
Query 3 Relates to regular enquiries received from Ministers and the
Commonwealth about Nature Refuges that are within a particular Bioregion.
Question: Provide the number of Nature Refuges in the Wet Tropics Bioregion that
are greater than 100ha and occupy the whole of lot.
Data: Datasets required for analysis are the Gazetted Nature Refuge and the
Bioregional dataset
Method: Conditional Query is selected to provide the answer as the condition is
attribute based.
Process: Figure 4-7 illustrates a simple process model that was created to streamline
the process required to answer the question. The following three criterions must be
fulfilled: Nature Refuges have to be located in a specific Bioregion, they must be
larger than 100 hectares and they have to occupy the whole Lot/Plan. For that
purpose one of the three basic operators in Boolean logic AND was used as it acts
like a filter and will not give the combination of the three criterions but only the
records that fulfil all three conditions.
Figure 4-7 Query 3 Process
Chapter 4: Data Integrity and Analysis
Page 62
Query 4
In Australia, mining rights over-rule most other interests, including agreements that
aim to protect important areas in perpetuity. There are numerous Nature Refuges and
conservation areas in Queensland that are threatened by the mineral and coal
industries. Query 4 is related to the Ministers request for a Government decision to be
made regarding the potential for certain exemptions on Nature Refuges from mining
interests.
Question: How many hectares of Nature Refuges are currently affected by mining
interests in Queensland, what percentage of each Nature Refuge is affected and the
types of mining activities undertaken?
Data: Datasets required for analysis are the Gazetted Nature Refuges, Mining claims,
Mining Leases, Exploration Permits, Petroleum Leases, Mineral Development leases
and the UTM Zones layer.
Method: Prior to the analysis process and in order to achieve the required results
some pre-processing of the data was necessary. The following combination of Data
Management and Analysis tools were used:
1. Merge and dissolve to combine Mining feature classes into a single polygon.
2. The UTM zone feature class was dissolved based on the zone field (e.g. zone
56, 55 or 54)
3. Split tool was used to separate the Nature Refuge feature classes and Mining
class (both in GDA94) to individual MGA Zones.
4. Reproject was used to project the output feature class from the above step to
the associated projection (e.g. MGA94 Zone 56, or MGA94 Zone 55, etc.)
5. Clip tool was used to work out the overlapping area of Nature Refuge and
Mining Areas.
6. The total area and the total impacted area of each Nature Refuge were
calculated by summarizing the table by field NAME. Summary statistics to be
included in the output table were chosen from the total GIS_AREAHA and
overlapping area SHAPE_AREA.
Chapter 4: Data Integrity and Analysis
Page 63
7. The summary tables were merged to one table, and summarized on NAME
again. The percentage (%) of impacted area was calculated using the
following field calculation: 100 * [SUM_Shape_area] /
([SUM_GIS_AREAHA]*10000)
The tools used to answer Query 4 were chained together in one operation. Figure 4-8
illustrates the repetitive task model created in Model Builder for this query. The
model will be used to automate the workflow and to provide the answer to one of the
most frequently asked questions relating to mining activities currently undertaken in
Queensland. The model will enable the Nature Refuge Branch to provide a timely
response to these enquiries.

4.3 CHAPTER SUMMARY
The functionality GIS offers is based on the demand for analysis and a spectrum of
capabilities ranging from simple to complex. Many organisations still utilise the middle
of this spectrum. This chapter presented the complex end where new GIS
development makes the most societal impact. At the end of the spectrum is a
simulation-based research and development model that gives the necessary power to
challenge and minimise impact on conservation (Tomlinson 2000).
Chapter 5: Results

5Chapter 5: Results
“Results from statistical analyses may be graphed and spatial models
may be mapped, and these items may be scrutinized in relation to any developing
hypotheses” (MacEachren 1994b)
This chapter presents the results of this research. The advanced functionalities of GIS
used in this study have addressed the map clarity issues and provided a new and
improved Nature Refuge Protected Area Plan. The Nature Refuge spatial datasets
have been designed to aid effective spatial data interchange “Congratulations have
been received from the Commonwealth’s National Reserve System team on the
standard of the spatial layer in meeting their requirements for smooth system
integration” ( DERM, 2009 Appendix 5).
The Nature Refuge Geodatabase created is a knowledge base that facilitates analysis,
and provides vital information on Nature Refuge assets. The GIS gazettal framework
has been tested using multiple simple and complex spatial queries. The Nature Refuge
Branch has now the capability to perform various system inventory searches, basic
database work such as deriving the exact number of Nature Refuge properties that are
located within a specific Bioregion. The power of this study is embedded in Phases 4
and 5 of the GIS gazettal framework and the ability to provide answers to questions
challenging negative impact on conservation. From the following results, it can be
seen that the GIS gazettal framework has increased the time efficiency and operational
performance within DERM. Consequently, the hypothesis has been proven. Extracts
from Appendix 6 provide evaluation and evidence of the success of this research.
The following study objectives were accomplished in this research endeavour:
Investigate and utilise GIS and its advanced functionalities to enhance the
mapping component of the Nature Refuge Program.

5.1 THE NATURE REFUGE PROTECTED AREA PLAN
Protected Area Plans (PA’s) representing the boundaries of a Nature Refuge,
including any zoning or exclusion areas associated with the protected area are now
produced in GIS. The templates created provide the effectiveness and timeliness
required to produce these plans. They conform to the technical standards proposed by
the author. Figure 5-1 illustrates the Queensland’s Nature Refuge Protected Area
Plan.
“Data integrity improved with the collection of GPS point data and the seamlessintegration into the office environment”.
“Protected Area (PA) plan templates developed in conjunction with Guidelines andProcedure Manual have streamlined processes and improved delivery timelines andcosting projections”.
“Outsourcing of PA plan production to Councils to meet tight timeframes andfacilitate standardized delivery of the Koala Program is now feasible”(DERM, 2010 Appendix 6).

5.2 THE NATURE REFUGE SPATIAL DATASETS
Visual representations (in the form of diagrams, graphs, and maps) have long been
assumed to facilitate thinking and problem solving, and research has focused on how
visual representation interacts with human cognition to do so (Larkin and Simon,
1987).
The following figures illustrate the presentation maps that will be provided to the
landholders, program managers and policy makers to aid the decision making process.
Figure 5-2 illustrates the Gazetted Nature Refuge spatial layer created in Phase 3 of
the research design these are protected areas of land with high environmental value.
The gazetted spatial layer is available publicly and is free of charge. Figure 5-3 shows
Proposed Nature Refuge properties these properties are awaiting a finalisation of a
conservation agreement and gazettal. This layer is available internally within the public
sector. Figure 5-4 represents properties that are being identified as potential protected
areas and are in the first stage of tendering. The potential spatial layer is only available
within the Nature Refuge Branch of DERM. By graphically presenting the results of
analysis spatial dimensions and relations are revealed. This is not usually evident when
presenting spatial data in tabular form (MacEachren 1994a).
“Applicants for Nature Assist rounds 2 and 3 (which provide incentive funding toprivate landowners entering into a nature refuge) were able to be transparentlyassessed and accurately compared by providing GIS data in vector and raster formatsto be applied to a CSIRO metric”.
“Reliable data is now readily available for data modelling with complex programs suchas numbers, types and extent of Mining on Nature Refuges, Koala habitat underprotection in Queensland, Native Title claims, Easements, Leases and sub-leases”.
“Gazetted, Proposed and Potential spatial layers were developed as tools for scopingand evaluating future planning and development”.
“GIS analysis mapping is now an integral part of all reports emanating from the NatureRefuge Branch and has been adopted by higher levels of management and publicly as avisual form of presentation to best represent the continued development and impact ofthe program”.
“GIS based mapping has assisted in funding applications to support the growth andimpact of the program’s acceptance by the community” (DERM, 2010 Appendix 6).

now be produced effortlessly as a standard report. The graph illustrates that in 2009
there were 366 Gazetted, 116 Proposed and 174 Potential Nature Refuges. The ability
to perform this type of analysis has in turn equipped Nature Refuge Branch with the
ability to project future growth and acquire funding for the ongoing management of
Nature Refuges.

5.3 THE NATURE REFUGE GEODATABASE
Spatial alignment inaccuracies were highlighted when the Gazetted Nature Refuge
spatial layer was overlayed and then cross- checked to the Protected Areas of
Queensland Estate boundary layer and DCDB. Figure 5-7 illustrates the Gazetted
Nature Refuge feature class overlayed with the DCDB and Protected Areas Estate.
The Nature Refuge Geodatabase has enabled a seamless boundary alignment between
the three layers to be achieved by enforcing topology behaviour.
“The GIS digital database now maintains accurate spatial data for storage,
retrieval, research and analysis” (DERM, 2010 Appendix 6).

5.4 ATTRIBUTE AND SPATIAL QUERY RESULTS
Figure 5-8 shows the simple select by attributes query used to answer question 1
(refer to section 4.2.1 Testing the Research Design). The returned records showed
there are currently 309 gazetted Nature Refuges in Queensland. The statistics show
the exact sum of land in hectares to be 765,000ha this is amount of land currently
protected in Queensland under the Nature Refuge Program.

Figure 5-9 shows the results for Query 2 ( refer to section 4.2.1 Testing the Research
Design) this spatial query was executed by selecting features in one layer based on the
locations of features in another layer (ESRI 2005). For the purpose of achieving
spatial data integrity attention was drawn to features from the Gazetted Nature

Refuge dataset that crossed the outline of the Protected Area Estate dataset. The
process returned sixty-two records highlighting inaccuracies between the two layers.
Figure 5-9 Query 2 Results highlight the Nature Refuge boundaries that overlap with theProtected Areas Estate boundaries.
Figure 5-10 shows the results of the conditional query selected to answer question 3
(refer to section 4.2.1 Testing the Research Design). Four Nature Refuges occupying
the whole lot on plan are larger than 100 hectares and are located in the Wet Tropics.
Figure 5-10 Shows the tabular view of results answering the question presented in Query 3How many Nature Refuge’s occupy the whole of lot, are greater than 100 hectares and are
within the Wet Tropics Bioregion?

illustrates the output table where the field NAME depicts the Nature Refuge, the
FREQUENCY field represents the number of lots associated with this Nature Refuge,
the SUM_GIS_AREA is the total area in hectares and the SUM_Shape_area depicts
the total impacted area. To validate the model results an additional and commonly
applied validation approach was performed consisting of a visual comparison and
confronting model outputs with expert opinion.
Figure 5-11 Illustrates the Query 4 results in tabular view. The results show the number andimpact percentage of Nature Refuge’s in Queensland threatened by the mineral and coal
industries.

5.5 CHAPTER SUMMARY
Critics are concerned that GIS models contain substantial uncertainties. Uncertainties
are present in any type of model. One thing is for certain if we wait for uncertainties
of these models to be completely eliminated before policy is implemented to preserve
valuable ecosystems then we risk losing those ecosystems. Land disturbance is already
underway throughout Queensland mining activities are carried out on Nature Refuge
Land. Therefore new methods that both appreciate the models level of uncertainty but
also acknowledge the urgency of environmental challenges are needed (Paegelow and
Camacho Olmedo 2008).

6Chapter 6: Benefits and Discussion
This chapter presents and discusses the various benefits derived from this study from
within the diverse sections of the public and private sectors. Commencing with the
data custodians of the Nature Refuge spatial dataset and concluding with the
customers that use it. It is appropriate to disclose that the GIS gazettal framework
proposed by this study has been adopted, successfully implemented and is functioning
within DERM.
“The system is now a central element of the Nature Refuges Program. As you areaware, the Program has grown at a much faster rate than anticipated from a littleunder 100,000 hectares with Nature refuges in 1994 to nearly 2,100,000 hectareswith the next gazettal in July, now comprising a little over 1% of Queensland’s landarea and the second largest extent of protected area (after National Parks) in theState. The GIS system has been a major factor in our maintaining an effectiveadministration throughout this growth, and has developed a series of potentials withanalysis and reporting that are essential as the program has grown from minor tomajor status as a conservation mechanism” (DERM, 2010 Appendix 6).
Figure 6-1 depicts the Nature Refuge gazettal history and the remarkable increase of
these protected areas from 1994. In 2005 the author introduces GIS cartography to
the Nature Refuge Program. The first protected area plans produced in GIS were
gazetted in June 2005. It can be argued that by introducing GIS a significant
contribution was made towards the increase in numbers.
Chapter 6: Benefits and Discussion
Page 83
Figure 6-1The Nature Refuge Gazettal History
Every Nature Refuge required a protected area plan. The map template, map
symbology and map quality standards developed by this research notably reduced the
amount of time required to produce a plan. The final plan is subject to ongoing
negotiations between the landholder and the Nature Refuge Regional Officers
therefore many draft plans are required before a protected area is gazetted. GIS dealt
with reported changes instantaneously and thus time and cost effectively. The GIS
gazettal framework has given the Nature Refuge Branch an integrated systems
approach to collect, present store and analyse knowledge on their resources. The
study has demonstrated GIS can be used as a methodological tool for:
Decision Support - The Nature Refuge Branch can present the Nature Refuge
Protected Area Plans with confidence in their correct, technical, and legal aspects.
The clarity of the plans and timely manner in which they are produced, means the
Nature Refuge Officers can communicate with landowners during the negotiations
process with minimum difficulty. The spatial datasets developed by this research can
be spatially integrated and analysed offering the ability to project future growth and
determine priority areas for the program to target. The Nature Refuge Geodatabase is
a GIS rich information and knowledge resource for the public sector. It not only
provides references but also becomes a consulting tool for problem solving and
decision making (Chen 2008). The model developed by this study offer fasts analysis
Chapter 6: Benefits and Discussion
Page 84
and provides supporting evidence on mining activities affecting the Nature Refuges.
Modelling environmental dynamics aids in the understanding and anticipation of future
evolutions. Their simulation supports decision-making for environmental management
(Paegelow and Camacho Olmedo 2008).
Reporting - Creation of graphs and maps describing spatial relationships can now be
produced easily as a standard report. Enabling the Nature Refuge Branch to project
future growth and acquire funding for the ongoing management of Nature Refuges.
The capacity to bring covenanting information (Internal Zones) into GIS is essential
for the Nature Refuge Program as it can then easily be analysed for reporting on the
effectiveness of covenants in achieving biodiversity conservation on private land.
Tracking Performance – Analysis in a spatial context provides the capability to
monitor the Nature Refuge properties. This in turn has alerted the Nature Refuge
Branch to problems associated with subdivisions occurring within a Nature Refuge
without their knowledge. Analysis on the spatial datasets revealed that a particular
property has undergone a sale of one lot and a re-survey which has a new lot/plan
reference in addition a part of the Nature Refuge has reverted to Unallocated State
Land (USL). This has highlighted the issue of a new owner wanting a separate
Conservation Agreement stating they are only responsible for their own property &
not tied to the original owners. Another Nature Refuge has had two boundary
realignments done without the Nature Refuge Branch’s knowledge.
Compliance The Commonwealth contract for a national database of Nature Refuges
was able to be fulfilled easily due to data compliance with their systems. The provision
of the Gazetted Nature Refuge spatial dataset to CAPAD in a format that complies
with their technical specifications supported this.
Conservation
The capacity to spatially network Nature Refuges, Regional Ecosystems, Biodiversity
Planning Assessments and Koala Habitat has resulted in a few Nature Refuges been
made exempt from mining activities. Currently research is being undertaken to see if
Chapter 6: Benefits and Discussion
Page 85
this can be extended to include other Nature Refuges. The purpose of the model
developed in Chapter 4 of this thesis is to assist this process. The model can be easily
adapted and used to inform where best to target conservation in Queensland.
6.1 INTERNAL DERM WORK GROUPS
The Nature Refuge Gazetted and Proposed spatial datasets are provided together with
metadata and a symbology layer to the Environmental Information Systems Unit
(EISU) for inclusion into the Enterprise GIS environment. Previously updates were
carried out several months after a gazettal due to labour-intensive manipulation of the
boundary data. Now they are integrated and available for viewing and downloading
within a few days after every gazettal. Figure 6-2 illustrates a session of ECOMAPS
(DERM’s internal mapping system) the Gazetted and Proposed Nature Refuge
boundaries overlayed with State Forests and Timber Reserves, National Parks, and
Conservation Parks.
Figure 6-2 ECOMAPS Session (DERM 2009)

The planning and development of future Nature Refuges relies heavily on the
provision of up to date spatial data to demonstrate the success of the program to
future applicants. The ability to present a visual display to regional staff and their
clients of reliable data provides security to clients not familiar with the program. The
timely and efficient distribution process enables the Proposed Nature Refuge Dataset
to operate as an alert mechanism for Governments personnel state wide. The results
presented in Figure 5-11 show there are currently one-hundred and sixty Nature
Refuges affected by mining activities. Seventy-five are properties proposed to be
protected.
6.2 OTHER BENEFITS
6.2.1 Federal Government
The Department of Environment, Water, Heritage and the Arts, (DEWHA) sources
data on protected areas, including Nature Refuge areas every two years through
CAPAD. CAPAD provides both spatial and tabular information about government
and privately funded protected areas both within Australia and overseas. Data is
contributed by State/Territory nature and conservation agencies. The Nature Refuge
Branch has the capability to provide NR boundaries in a format compatible to
CAPAD systems. This in turn has numerous benefits amongst others it promotes
national coordination and information sharing and facilitates visualisation of these
properties and where their conservation efforts are fitting in with those of other
agencies and organisations (DEWHA 2008).
6.2.2 State Government
Previously only hardcopy protected area plans were sent to the former Department of
Natural Resources and Water (DNRW) for the incorporation of these boundaries into
the DCDB. The plans were then scanned; geo-referenced and in some cases Nature
Refuge boundaries were traced using the onscreen digitising technique. This practice
has now been totally omitted since the Nature Refuge Branch has the capability to
provide these boundaries in a compatible digital format.
Chapter 6: Benefits and Discussion
Page 87
The Department of Mines and Energy automatically receives updates on Gazetted and
Proposed Nature Refuges this in turn enables improvements in their planning and
management strategies.
6.2.3 Local Government
The spatial datasets developed by this research are significant to utility and Local
Government information systems particularly as most of their business information
and transactions are related to the land parcel.
The majority of Councils run their own covenanting programs, and many, especially in
South East Queensland, are also delivering Land for Wildlife. The GIS enables
mapping and analysis of the various forms of voluntary conservation agreements, and
possibly more importantly, what they are protecting. If a common network of
voluntary conservation programs was to be formed, then subject to the wishes of
landholders, GIS could be used as a decision tool in defining the most appropriate
mechanism relative to given properties. Analysis could also then be applied across a
broad spectrum of conservation interests.
6.2.4 AgForce
Apart from the very significantly enhanced reporting capacity the GIS offers and the
ability to demonstrate overall growth, distribution and values, there is potential to
analyse the proportions of properties that are or are not subject to Nature Refuges,
and ultimately the zones within Nature Refuges and their implications relative to
production capability. Such analysis would be a major element in reviewing the
developing and potential balance between production and conservation of varying
intensities within properties, within a bioregion and ultimately relative to the state
overall.
6.2.5 Private Sector
Thematic mapping of key themes that are sensitive to any type of planned
infrastructure is undertaken prior to construction. This step requires the protected
areas to be overlayed with various other environmental and infrastructure datasets. A
desktop assessment of the study area is carried out to show that the respective
Chapter 6: Benefits and Discussion
Page 88
corridors or sites recommended are ones that both mitigate risk and best seek
ecological sustainability.
Selection studies are derived from the desktop analysis of data from a range of
sources, applied in a virtual context through the use of GIS. When analysing the
Nature Refuge spatial data the Project Manager’s can be confident that they are
working with the best data.
6.3 CHAPTER SUMMARY
Various benefits of the research design have been presented in this chapter. The
Nature Refuge Mapping Program has gained a powerful ally in GIS. A system that
supports the decision making process, provides visual evidence for reporting purposes
and offers a way to streamline the work procedures. When interrogated supplies
answers, offering decision makers the ability to challenge the negative impacts on our
environment. It is not the intention of this research to claim credit for the amazing
increase in Nature Refuge protected areas from when GIS was first introduced in
2005. Nevertheless if this research contributed only 10 percent to that boost then it
was a beneficial study.
Chapter 7: Conclusions
Page 89
7Chapter 7: Conclusions
“No GIS can be a success without the right people involved. A real-world
GIS is actually a complex system of interrelated parts and at the centre of this
system is a smart person who understands the whole” (Tomlinson, 2003 p. 1)
7.1 SUMMARY
The hypothesis that GIS can streamline the gazettal process and improve the spatial
integrity and quality of Nature Refuge boundaries has been proven in this research.
In doing so, this research was to address the current major factors affecting a timely
gazettal by using the capabilities of the desktop GIS as a methodological tool for the
presentation and analysis of Nature Refuge boundary. Chapter 3 focused on the major
constraints affecting a timely gazettal process. Data collection techniques, map
presentation and data integrity. Chapter 4 further developed the GIS gazettal
framework and dealt with issues such as spatial data accuracy, analysis and process
modelling. The Nature Refuge Geodatabase was developed and the GIS gazettal
framework was tested through analysis and multiple queries. The results and benefits
of this research provided evidence on the enhanced map presentation and the spatial
integrity and quality of Nature Refuge boundaries. The study has produced a model
informing where best to target conservation effort and investment when dealing with
mining issues. This strategic approach offers another avenue for the Nature Refuge
Program to follow in order to protect and conserve and therefore contribute to
preserving the environment.
7.2 CONCLUSION
GIS can make a significant contribution and play a key role in encouraging
biodiversity conservation on private land. When planned and implemented
appropriately its analytical environment can not only support the decision making
Chapter 7: Conclusions
Page 90
process but it can take a lead role in this process. The Nature Refuge Mapping
Program is a project currently in progress within Nature Refuge Branch. Three phases
of GIS gazettal framework have been implemented and proven to be of invaluable use
The GIS gazettal framework has enabled spatial data compliance to other
Government systems and provided the capacity to spatially network Nature Refuges.
The map template, map symbology and map quality standards developed by this
research significantly reduce the amount of time required to produce a plan and
therefore the work procedures leading towards establishing a Conservation
Agreement and gazettal of a Nature Refuge have been rationalized.
The labour-intensive manipulation of the boundary data is no longer necessary as the
boundaries are now integrated and available for viewing and downloading within a
few days after every gazettal. GIS has greatly improved the spatial integrity and
quality of Nature Refuge boundaries. Vital information on Nature Refuge assets can
now be retrieved in a more efficient and timely manner. The main aim of this research
was to adopt a scientific approach and develop a GIS framework for the Department
of Environment and Resource Management that will streamline the gazettal process of
Nature Refuge’s in Queensland. This aim has now been accomplished.
7.3 LIMITATIONS
The GIS discipline is fast paced technology therefore regular upgrades software and
hardware is crucial. Another key obstacle is that the technologies require the user to
learn the system’s language. In addition, geospatial technologies are not
“collaboration friendly” they impede rather than facilitate group work (MacEachren
and Cai 2006).
GIS can manage data and information, but it is generally not smart enough to do all
the work. Many operations in the GIS require human involvement (Chen 2008).
Therefore adequate and in depth training could be a limitation to successfully building
on the research design. Another constraint of this study would be the fact, that the
sheer volume of spatial data representing all protected areas of Queensland has limited
the research to only investigating the Nature Refuge Protected Areas.
Chapter 7: Conclusions
Page 91
7.4 RECOMMENDATIONS
It is appropriate to recognize enhancements that would be useful in continuation of
this research. These can be divided into three categories:
Further investigations into new geodatabase capabilities
Increasing the sophistication of the modelling techniques presented
Using the applications of GIS to identify/target land for Nature Refuges
The Nature Refuge Geodatabase design is suitable for moving forward therefore
building on the existing design and improving the efforts already made should be a
further research focus. The mining model contains a number of interrelated processes
alternative scenarios could be considered as the model can be easily adapted and the
mining data can be replaced by other negative environmental impacts affecting the
Nature Refuges. New functions and capabilities can be added to these models.

REFERENCE
From the initial contact made with V1atka Varagic it was apparent that she held extensive corporate knowledge and spatial data management expertise in all of the Protected Areas currently managed by the Department of Enviromnent and Resource Management. Her seamless entry into the Departments data bases enabled an i=ediate delivery of services and products which was essential in meeting the tight time frames required.
Vlatka consistently demonstrated a vision and passion for her work throughout Stage 1 oftbe contract which incorporated -
I. The preparation of Protected Area plans from a backlog of Gazetted Nature Refuges dating fi'om April to December 2008.
2. Redesigning the Nature Refuge's corrupted spatial layer, updated all data entries aud formatting the data to integrate into the Department's Ecomaps.
3. The design and development of a new spatial layer of Potential Nature Refuges and Expressions of Interest for the Nature Assist Program throughout Queensland for future planning and analysis.
V1atka's familiarity with the Nature Refuge Program was integral to the successful development of this spatial data within the GIS platfonll.
Communication on all levels was provided within the program and areas were suggested for strategic planning and development. Clear and concise progressive reporting throughout the contract led to its extension to incorporate the 3rd part of Stage I.
The GIS layers for Nature Refuges and Coordinated Conservation Areas and Potential Nature Refuges are now operational wi thin the Department.
Congratulations have subsequently been received from the Conllllollwealth's National Reserve System team managing the national CAP AD database on the standard of our spatial layer in meeting their requirements for s11100th system integration.
V1atka's consultancy and advisory role was excellent from the initial contact to completion and her staff training has provided the department with confident and efficient GIS operational staff.
The Department's expectations were exceeded with the delivery of this contract and the highly professional manner, confidentiality and sensitivity displayed has impressed staff and management.
The Nature Refuges Branch was very fortunate to be able to contract Vlatka Varagic of Ma un sell as her in-depth knowledge of Departmental data bases has equipped her with skills and knowledge which we found invaluable.

OUTCOMES OF THE INTRODUCTION OF THE GIS FRAMEWORK FOR THE NATURE REFUGE BRANCH
The system is now a central element of the Nature Refuges Program. The Program has grown at a much faster rate than anticipated from a little under 100,000 hectares with Nature refuges in 1994 to nearly 2,100,000 hectares with the next gazettal in July, now comprising a little over 1 % of Queensland's land area and the second largest extent of protected area (after National Parks) in the State. The GIS system has been a major factor in our maintaining an effective administration throughout this growth, and has developed a series of potentials with analysis and reporting that are essential as the program has grown from minor to major status as a conservation mechanism.
Specific key points include:
The GIS environment enables boundaries of Nature Refuges and internal zones to be spatially referenced.
• Data integrity improved with the collection of GPS point data and the seamless integration into the office environment.
• Protected Area (P A) plan templates developed in conjunction with Guidelines and Procedure Manual have streamlined processes and improved delivery timelines and costing projections.
• Outsourcing of P A plan production to Councils to meet tight time frames and facilitate standardized delivery of the Koala Program is now feasible.
• Commonwealth funding for the development of a national database of nature refuges was received for stage 1 and stage 2 is on track for 2010. The Commonwealth was impressed with the standard and extent of our spatial layer in comparison with other states of Australia as CAP AD standards had been adopted from the onset of its development.
• Amendments to existing Nature Refuges are simplified with historic referencing of spatial data.
102
GIS digital database maintains accurate spatial data for storage, retrieval, research and analysis.
Applicants for Nature Assist rounds 2 and 3 (which provides incentive funding to private landowners entering into a nature refuge) were able to be transparently assessed and accurately compared by providing GIS data in vector and raster fOlmats to be applied to a CSIRO metric. Reliable data is now readily available for data modelling with complex programs such as numbers, types and extent of Mining on Nature Refuges, Koala habitat under protection in Queensland, Native Title claims, Easements, Leases and sub-leases. Gazetted, Proposed and Potential spatial layers were developed as tools for scoping and evaluating future planning and development.
GIS analysis is able to be performed on validated data for performance reporting, future analysis growth of the program and fiscal management.
GIS analysis mapping is now an integral part of all reports emanating from the Nature Refuge Branch and has been adopted by higher levels of management and publicly as a visual form of presentation to best represent the continued development and impact of the program. GIS based mapping has assisted in funding applications to support the growth and impact ofthe program' s acceptance by the community.
Data custodianship of spatial data has elevated the awareness of and the importance of the program.
The ability to validate, check geometry and perform topology checks on the spatial data to assure its integrity is an essential requirement as data custodians. This affords a reliability of data information essential to the business functions of the program.
• The Nature Refuge Program is tasked with growing 7,000,000 million hectares of land by 2020. The GIS systems developed have been integral to this achievement along with the commitment and dedication of all staff involved in its implementation and direction.
The GIS functionality has elevated and streamli",ed the delivery of data which has been seamlessly integrated into similar DERM environments to improve the protection of land of high environmental values in Queensland.
