Geoimage Pty Ltd is a privately owned

Australian company and a leading supplier

of satellite imagery, image processing and

GeoSpatial services to the user community.

The company was established in Brisbane

in 1988 and has additional offices in both

Perth and Sydney.

Our mission is to provide professional

service and quality advice and solutions to

our clients.

Our success can be attributed to our

professional and independent approach to

service delivery, striving to determine the

best outcome for the client while offering

value for money.

Geoimage has recently expanded

its capabilities to offer a full range of

GeoSpatial solutions, to take advantage

of the synergies between commercially

available imagery and other spatial data

and information. Based on a flexible and

collaborative business model, this extended

service offers clients the opportunity to

undertake a diverse range of projects using

relevant spatial data themes.

Our approach to GeoSpatial Solutions

is to align with the business needs of

clients, to design solutions that integrate

commercially available imagery and GIS

data themes to assist in decision making,

data interrogation, data publishing and

dissemination.

Geoimage has established a rapidly

expanding spatial data warehouse and

geospatial standards to accommodate a

range of discipline-specific tasking and

project requirements.

Data is warehoused locally on Geoimage’s

servers but Geoimage can customise

this generic warehouse data for specific

projects which can be hosted via WebGIS

to enable access by clients and their

nominated and approved associates.

Geoimage has in-depth knowledge of

archival material from a wide range of

satellite sources and this, coupled with

extensive knowledge of Local, State and

Federal Government spatial data, provides

a framework that will support most client

applications and requirements.

Geoimage offers professional and

independent advice on the supply and

application of commercially available

satellite imagery and spatial datasets.

Geoimage is now offering targeted

solutions integrating, analysing, modelling

and visualising spatial information.

We continue to provide timely delivery,

dedicated follow-up and professional

customer service.

new capture when this is available.

Geoimage can provide access to the

following satellite imagery:

✜ QuickBird, WorldView-1 and

WorldView-2

✜ IKONOS and GeoEye-1

✜ SPOT and Pleiades, when

commissioned in late 2010

✜ ALOS and JERS

✜ Worldwide ASTER

✜ Radarsat and Resourcesat

✜ Australian Landsat TM and MSS

✜ Worldwide Landsat

Geoimage can also provide access to

✜ Aerial photography and LiDAR through

a variety of aerial survey firms

Imagery provides valuable context and

information content. Understanding which

source(s) are most appropriate for your

project is essential. Geoimage can provide

impartial advice to assist your selection.

WORLDVIEW-2 DATA NOW AVAILABLEThe DigitalGlobe Worldview-2 satellite was

launch in Oct 2090 and is now supplying 0.5m

pan and 8 band multispectral imagery of

the world. This imagery represents a sigifant

advancement over previous VHR satellites and

is being used for a wide variety of applications

including shallow

water mapping,

vegetation

mapping, DEM

production, etc

The synergies between imagery and other spatial datasets

become most powerful when combined into an integrated

geospatial framework. How these complementary sources

of information can be used depends on the range and

magnitude of the queries that a user or analyst asks of

that data. Geoimage has recognised the business benefits

in offering a coordinated approach,

utilising the advantages of commercially

available data and streamlined technical

methodologies.

Geoimage is a vendor-independent

company, using the best and most

appropriate technologies to solve

solutions. Within GeoSpatial, this

includes both vector and raster systems, web and desktop

environments and niche modelling programs to extract

information for our clients. Our team has experience in a

broad range of markets

and applications, providing excellent understanding of the

potential for geospatial to contribute to business outcomes,

with a realistic return on investment.

Geoimage recognises that geospatial solutions are generally

part of a bigger picture. By working collaboratively with

a wide range of discipline experts in areas as diverse

as environment and ecology, infrastructure feasibility

and concept design, climate change risk assessment,

visualisation and urban design, to name a few, Geoimage

coordinates a project team that suits not only the technical

requirements of a project, but also the commercial and

resource imperatives. We believe that geospatial services

potentially contribute to the lifecycle of most projects and

we assist with embedding these sources of relevant, current

and accurate information into the business processes of our

clients. Having the flexibility to be responsive but offering

targeted solutions is seen to be a strong characteristic in this

competitive marketplace.

Geoimage is happy to work with clients

to develop the range of services to meet

your needs.

Our range is constantly evolving to reflect

changes in technology, collaborations and

demand.

A coordinated approach to GeoSpatial Solutions

Just some of our GeoSpatial services...


Collaboration is the keyGeoimage’s GeoSpatial team has established

strategic relationships with organisations to

offer integrated services around ecology, flora

and fauna assessment, climate change risk

assessment, environmental management

and impact assessment, flood inundation and

modelling, visual impact, land and resource

management and primary production.

“Being able to hand-select organisations

based on their professional capability and

ethical approach to business is

essential. We can offer solutions

with the confidence that our

clients will benefit from the natural

synergies between all project team

members and that the resultant projects will

reflect the outcomes of operational

teamwork based on trust and

collaboration” says Andrea Herklots,

GeoSpatial Manager for Geoimage.

Terrain or surface data forms the

basis of many geospatial applications.

These models generate a 3D surface

for use in geospatial applications and

visualisation and to correct for relief

distortion, enabling integration of the

imagery with other projected spatial

datasets.

Geoimage is able to generate surface

models from satellite sensors that track

in stereo. These include WorldView-2,

WorldView-1, IKONOS, GeoEye-1,ALOS

PRISM and SPOT HRS. The suitability of

these satellite sources is dependent on

the vertical and horizontal accuracies

required to generate the resultant

surface or terrain model and on the

amount of detail required.

The accuracy of a surface model will

depend on many factors, including:

✜ the accuracy and spread of the client

supplied control data

✜ The accuracy with which the control

points can be identified in the stereo

imagery

✜ The requirement for surface

features to be identified (surface

models reflect all features including

vegetation and buildings)

✜ Data gaps arising from shadow and

steep slopes where data has not

been acquired by the satellite

✜ Environmental factors that impact

the imagery including atmospheric

conditions that may reduce the

continuity of the surface

Where satellite sources are not

appropriate, Geoimage collaborates

with aerial service providers who

can fly airborne LiDAR sensors (Light

Detection and Ranging) to generate

high resolution and highly accurate

digital terrain and digital surface

models and aerial photography.

“Having worked with imagery for the past

21 years, expanding our range of services to

offer more value-added capability is a natural

extension to our business. We are all excited

about the new opportunities that this will

offer our existing and potential clients.”
