locationmatters is produced by the Information and Lands Services Division of the Tasmanian Department of Primary Industries, Parks, Water and Environment (DPIPWE).

This newsletter aims to provide professionals and the general public with interesting articles and news about land information in Tasmania.

We encourage you to provide feedback or ideas for future issues and hope you take advantage of this opportunity to keep in touch. Comments can be emailed to geodata.clientservices@dpipwe.tas.gov.au

Welcome to the first edition of locationmatters. This newsletter has been produced to provide information about the range of programs, projects, products and

services for which the Information and Land Services Division (ILS) of DPIPWE is responsible.

Most people in Tasmania will at some time need to access or deal with land information products and services provided by the Tasmanian Government, including the LIST, TASMAP products, land titles or survey plans. Some people may also need to use Crown land management or valuation services. Many will also access Service Tasmania shops. ILS manages the programs, products and services associated with each of these. Through this newsletter, we hope to keep you informed about new developments and progress with existing projects as well as introduce you to staff and the work they do. We also hope to promote various State and national initiatives relevant to the Tasmanian land information community.

This is an exciting time to be involved in this industry as the true value of spatial information in planning and decision making processes is being realised right across private business and public sectors.

The challenge we face is to improve our data, products and services to ensure we meet the expanding needs of government and the community. Jurisdictions worldwide are facing the same challenge. By keeping informed and up-to-date with national and international developments, we are looking for opportunities to leverage off and contribute towards new trends, ideas and technological advances. Within Tasmania, we are working with stakeholders to understand their needs.

In late 2009, the Tasmanian Spatial Information Council (TASSIC) published its first strategic plan for spatial information in Tasmania and we look forward to working with all stakeholders to help TASSIC achieve its vision for ‘abundant and useful spatial information within reach of all’.

While this edition centres primarily on the activities of Geodata Services Branch, we intend to broaden our focus to other areas of the Division in future editions and we ask for your feedback to ensure that we cover topics and issues that interest you. I also encourage you to ask questions and provide ideas that will assist us in improving our products and services for the benefit of the Tasmanian community.

TASMAP recently released a new edition of the Tasmanian Towns Street Atlas. Edition 8 includes 274 street maps covering all cities, towns and population centres in Tasmania. The new Street Atlas is an essential source of up-to-date street and location information and is used extensively by all of Tasmania’s Emergency Service organisations, as well as tourists and the general community.

New to this edition are additional Town Centre maps for fast growing areas such as Kingston, New Norfolk, St Helens, Smithton, Sorell and Wynyard.

TASMAP is the Tasmanian Government’s base mapping arm, managed by the Information and Land Services (ILS) Division of DPIPWE. TASMAP produces a variety of topographic maps including a wide range of series maps, national park maps, tourist products, the Street Atlas and a large range of other mapping products. TASMAP also captures and sells aerial photographs and is making available a range of historic charts managed by the Surveyor General of Tasmania.

The Tasmanian Government has been producing authoritative street directories in Tasmania since 1948. In recent years a new edition of the atlas has been produced every three years.

The new Street Atlas highlights significant growth in Tasmania over the last few years, with the addition of over 600 new roads and 10,000 new buildings and dwellings in towns and cities alone. Kingston has proven to be the fastest growing suburb by far, with over 500 new dwellings and 21 new suburban streets added since the last edition was published.

Underpinning the Street Atlas are the key framework datasets maintained and delivered through the Land Information System Tasmania (the LIST). These include Roads and Transport, Buildings, Topography, Community Facilities and Relief.

Tasmania’s framework datasets are maintained by the Geodata Services Branch of ILS, through a variety of means. These include the exchange of information in cooperative data sharing arrangements between ILS and other State and local government organisations, as well as comparison with aerial/satellite imagery, field capture and verification.

TASMAP’s advanced map production processes include the use of ESRI ArcGIS and Maplex, Adobe Illustrator and Avenza System’s Map Publisher software. Digital production enables the Atlas to be derived

directly from underlying digital spatial data. This significantly reduces the cost and time involved, at the same time validating the accuracy of the underlying data.

The Street Atlas is available for purchase from Service Tasmania shops, TASMAP resellers and agents, and the TASMAP website www.tasmap.tas.gov.au. The new edition can also be viewed as a background layer on LISTmap through the LIST. www.thelist.tas.gov.au

Aerial photography continues to be an essential part of the mapping and spatial data capture program in Tasmania today.

Shown here is the 1:25,000 topographic map over Howrah. Produced with data sourced from aerial photography. >>>

“People have always viewed the world from vantage points high above the landscape to better assess their surroundings. From the tops of rocky cliffs and the branches of the tallest trees, they discerned information vital to their survival, such as the identification of good hunting grounds or the approach of enemies.

The value of the “Bird’s-eye view” increased dramatically when it was captured in the form of drawings and later in maps that could be studied and shared with others. Photography and digital imaging enabled aerial views to be acquired rapidly, making it practical to obtain and analyse imagery for large areas of the earth’s surface. Today diverse human endeavours depend on a steady flow of images acquired from vantage points high above the earth to inventory, assess and manage resources.” *

Aerial photography is used to produce maps of the earth’s land, topography, natural resources and urban infrastructure.

Much of the information stored in a Geographic Information System (GIS) is generated from aerial photography. In addition, archived data serves as a valuable historical record that allows changes in land cover, biophysical processes and human activities to be monitored and analysed over time.

World War II saw a rapid development in the understanding and use of aerial photography and awakened people to its potential. After the war, the use of aerial photography increased exponentially, and the first aerial photographic survey of Tasmania was commenced in 1945. When completed in 1950, Tasmania was the only Australian State to have undertaken its own aerial survey. These aerial photos formed the basis for the state’s mapping program, and now also form a valuable record of Tasmania’s development at that time.

Aerial photographya bird’s eye view of the world

Aerial photo of Howrah taken in 1946, shortly after the commencement of the first aerial photographic survey of Tasmania. Compare the 1946 photo to that taken in 2004. Changes in land cover and development are evident.

Today, aerial photography is used in many different ways. One of the most fundamental applications is in photogrammetric surveying, the basis of modern topographic mapping. Other user-oriented applications Include land use planning, forestry, archaeology, environmental studies and site assessments.

The Department of Primary Industries, Parks, Water and Environment (DPIPWE) has its own aerial film camera and manages a flying program that covers approximately 20% of the State each year. An entire State coverage is captured on average every five years.

5This 1:20,000 scale photo of the barway entrance at Georges Bay, St Helens, was captured for Marine and

Safety Tasmania (MAST) to assist in the monitoring and management of the St Helens barway. Aerial

photography from 1998 to 2009 allows changes in the barway to be observed and monitored, assisting in long term solutions for improving navigation of the bar and

entrance channels. >>>

DPIPWE’s library of aerial photography is available to all members of the public. Digital images, contact prints and enlargements can be purchased through the Service Tasmania shop in Hobart.

DPIPWE undertakes a number of standard aerial photography projects at a variety of scales to ensure the best compromise between detail and coverage. These are shown in the table below.

When considering the scale of photography required for a specific project, you should consider suitability for the task, the cost of acquiring and processing, and the features that need to be identified in the image.

The size of a feature is determined by the scale of the photography, which in turn determines the pixel size. The smaller the area on the ground represented by each pixel, the finer the detail that can be identified.

In the image of the University of Tasmania’s Sandy Bay campus (right), buildings and cars are easily identified at a scale of 1:10,000. Photos can be enlarged up to 12 times before the image starts to lose quality. Where less detail is required, a scale of 1:24, 000 or 1:42, 000 may be adequate.

In the 2009-2010 flying season, DPIPWE acquired the following aerial imagery:

• standard 1:42,000 scale aerial photography for the South East quadrant of Tasmania

• East Coast towns at 1:12,500

• Hobart city centre at 1:7000.

The Client Services section of the Geodata Services Branch (Information and Land Services (ILS) Divison, Department of Primary Industries, Parks, Water and Environment) provides a single first point of client contact and support for a wide range of land information products and services.

The newly established group aims to provide a more efficient and strategic approach to the development and management of client relations.

The Client Services section provides assistance and support in the following areas:

Land Information System Tasmania

www.thelist.tas.gov.au

The Land Information System Tasmania (LIST) is a whole of government infrastructure that facilitates the discovery and delivery of integrated Tasmanian land information and services.

The LIST provides a secure platform from which a wide range of government land information and services can be managed, discovered and delivered in accordance with recognised standards, maximising the social, environmental and economic benefits of land information for all Tasmanians.

Client Services manages a helpdesk to support clients using the wide range of services and products delivered via the LIST including:

• LISTmap – web map viewer

• LISTdata – automated spatial data delivery

• LISTsubscriber services – including Tasmanian Online Land Dealings (TOLD), land titles & valuation services, stamp duty , council and water corporation certificates

• TSDD – Tasmanian Spatial Data Directory (metadata directory)

Spatial Data Delivery

Client Services undertakes tasks to support government, industry and the general public with spatial data delivery. This can range from delivering 1:100,000 topographic map data to bushwalkers, to providing digital property boundary data over farm holdings for the preparation of property management plans.

Data Agreements

Client Services develops and manages data agreements for the supply and exchange of a wide range of data, products and services delivered through ILS and other Divisions of the Department. These agreements range from mutually beneficial data sharing agreements through to legal contracts used to encompass commercial use of data.

Data sharing agreements are becoming more common, with many clients using these agreements to document and ensure the return of new, value-added or improved data to the relevant Division and future integration into framework datasets.

Data sharing agreements help to develop and improve client relationships and provide substantial benefits for users.

TASMAP Distribution CentreThe Tasmanian Government has been producing and distributing a wide range of authoritative mapping products since 1948.

TASMAP branding was introduced in the early 1970’s as a means of clearly identifying the Government’s mapping products. The use of a unique brand, which was designed to survive departmental changes, was quickly adopted by other State jurisdictions with VICMAP and SUNMAP being the best known.

Distribution of TASMAP publications is now managed by Client Services. In 2009, a new distribution centre was established within the Hobart CBD. This allows for more efficient and streamlined delivery of hard copy TASMAP products to clients within Tasmania, Australia and worldwide.

TASMAP products are also available for purchase from Service Tasmania Shops, through TASMAP resellers and agents, and online at www.tasmap.tas.gov.au

Client Services aims to deliver a professional and efficient service. We look forward to developing relationships with new clients and continuing to build on those already established. Should you have any questions, please contact us.

A new national telephone-based warning system that will alert Australians in the event of a life-threatening emergency began operation in December last year.

Following the completion of testing in Southern Tasmania, the system, named Emergency Alert, is now ready for operation in Tasmania. In the event of a life-threatening emergency such as a bushfire or extreme weather event, Emergency Alert will provide emergency services with another way to warn and advise communities.

Emergency Alert will allow emergency services to deliver messages outlining the nature of the emergency threat and recommended actions to mobile phones and fixed phones based on the billing address.

While every message is different, the alert will provide official and authorised emergency information on the current situation, advising people what actions need to be taken and also give them a reference to get further information or advice.

The system has the capacity to send 300 text messages per second and 1,000 voice messages per minute. Communities will be alerted to emergencies via a voice message to landline telephones based on the location of the handset, and a text message to mobile phones based on a subscriber’s billing address. Alerts will be sent to specific areas and people in those areas will receive the message around the same time.

The system will enable the incident controller to use the newly developed technology to select the geographical area on a map that needs to receive a warning and immediately dispatch that message to telephones in that area.

Emergency Services GIS is a dedicated unit within the Information and Land Services (ILS) Division of DPIPWE. The Unit has played a significant role in Emergency Alert for Tasmania. The maps, aerial photos, hazard datasets and address datasets that ILS maintains as part of Tasmania’s spatial data infrastructure assist the Emergency Services Incident Controller to identify the location that needs to receive the warning.

Every telephone number in Australia has an address that is matched with the Geocoded National Address File (GNAF) and plotted on the map, allowing the Incident Controller to select an area to receive a warning and/or advice.

The system can provide status reports on the community warning notifications, for example acknowledgement of receipt. This will assist in decision making processes for future actions and directions that might be required.

Since Emergency Alert became operational on 1 December 2009, it has been used 32 times and issued in excess of 109,000 messages. The system has been used in New South Wales, Victoria, South Australia and Queensland for flood, tsunami and bushfire emergencies.

The broadcasting of warnings to the public assists in preventing loss of life and reduces the economic impacts of an incident.

Future enhancements to Emergency Alert may include the ability to deliver messages to mobile phones based on user location as well as billing address. The Commonwealth Government is currently funding research into the feasibility of this enhancement.

Emergency Alert provides another way to warn and advise communities in the event of danger. Spatial information plays an essential role in the delivery of Emergency Alert messages.

New edition 1:250 000 TASMAPA new edition of the popular 1:250 000 TASMAP series has just been released. It comprises four maps covering all of Tasmania.

Recommended for regional planners or visitors intending to travel off the common tourist routes, the series is popular with drivers, cyclists and people wanting a regional overview of an area.

The series was first produced in 1980 by manual mapping techniques; this 4th edition is the first wholly digitally produced version. The data for the series was derived from statewide LIST datasets. Elevation tinting and hill shades are used in this series to give the terrain a 3D effect.

The maps are available in folded or flat form and may be joined together to create an impressive wall map.

New Photogrammetric ScannerILS recently installed a Leica DSW700 photogrammetric scanner workstation, which will be used to scan 210,000 frames of archived aerial imagery film negatives in a five-year program. Negatives will be scanned at 12.5 micron resolution (approximately 2100 dpi). This resolution meets all requirements for soft copy 3D photogrammetric applications and orthophoto production, as well as ensuring that this valuable aerial archive of Tasmania is preserved forever.
