  • SPOT5 satellite imagery captured between 17/07/2005 and 22/09/2006 over the South East Queensland Catchments. 50 SPOT5 single scenes comprising of 2.5m Panchromatic, 10m XI 4band multi-spectral and 2.5m fused XI 4band multi-spectral images. Mosaics comprising of a 10m pseudo natural colour ECW image clipped to the catchments extent and 2.5m pseudo natural colour ECW images clipped to 250k map sheet boundaries.

  • ACRES acquired SPOT 2 satellite images over the Namoi River, between the towns of Walgett and Wee Waa in December 1997 and November 2000. The November 2000 image consists of 12 scenes in which floodwaters, peaking at 8 metres, inundating the region are visible as green and light blue. Extensive flooding is evident. The December 1997 image shows the area of the Namoi River without floodwaters. The Namoi River catchment area is more than 350 kilometres long and stretches from Walcha in the east to Walgett in the west. Other river systems in the region include the Gwydir, Castlereagh, Hunter, Macquarie, Macleay, Manning, Culgoa and Condamine. You can find these rivers on Geoscience Australia's interactive Map of Australia.

  • Joint Release of the National ASTER geoscience maps at IGC The ASTER (Advanced Spaceborne Thermal Emission and Reflectance Radiometer) Geoscience Maps are the first public, web-accessible, continent-scale product release from the ASTER Global Mapping data archive. The collaborative Australian ASTER Initiative represents a successful multi-agency endeavour, led by the Western Australian Centre of Excellence for 3D Mineral Mapping (C3DMM) at CSIRO, Geoscience Australia and the State and Territory government geological surveys of Australia, along with other national and international collaborators. National ASTER geoscience map These geoscience maps are released in GIS format as 1:1M map-sheet tiles, from 3,000 ASTER scenes of 60x60km. Each scene was cross-calibrated and validated using independent Hyperion satellite imagery. The new ASTER geoscience products range in their application from local to continental scales, and their uses include mapping of soils for agricultural and environmental management, such as estimating soil loss, dust management and water catchment modelling. They will also be useful for resource exploration, showing host rock, alteration and regolith mineralogy and providing new mineral information at high spatial resolution (30m pixel). This information is not currently available from other pre-competitive geoscience data.

  • Switched off at the request of Karen Fearn. Gallery no longer maintained or supported. This satellite image gallery shows the expansion of Australia's major towns and cities in every State and Territory since the 1980's. Residential expansion, new infrastructure (such as freeways), and changes in environmental features including reservoirs and dams can all be seen through comparison 'swipe' imagery.

  • A world-first continental-scale mosaic of multi-spectral ASTER (Advanced Spaceborne Thermal Emission and Reflectance Radiometer) data is to be delivered for the Australian continent in 2012. ASTER data has improved spectral resolution compared with landsat TM and is providing a wealth of new national information on surface mineralogy, geochemistry and landform characteristics and composition. The new continental mineral maps can be readily combined with other geoscientific datasets and have applications in regolith-landform mapping, mineral exploration, geohazard research and impact analysis, as well as agriculture and land-use planning. Using satellite multispectral ASTER to map material on the surface of the Earth at a continental scale is the next step in delivering environmental, agricultural and resource exploration tools for users of remote sensing and GIS. Mapping mineral group information using targeted band combinations can find previously unmapped outcrop of bedrock, help define soil type and chemistry, and delineate and characterise regolith and landform boundaries over large and remote areas.

  • Australia wide mineralogical maps have recently been generated and released by CSIRO and Geoscience Australia using the 14 band satellite-borne ASTER imaging sensors. Seventeen map products related to surface composition have been produced for the geoscience community. Band parameters were developed based on spectral absorption features representing either abundance of mineral groups, specific minerals and their chemistry, vegetation cover or regolith related characteristics. A detailed study was undertaken, investigating the geoscience exploration capabilities of these newly released map products, individually, and integrated with airborne geophysics and digital elevation models over the Mt Fitton test site in northern Flinders Ranges, South Australia. This site includes the Mt Fitton talc deposits, gold prospects, and areas of hydrothermal activity and metasomatism.

  • All 1:250,000 scale NATMAP topographic maps available on CD in ECW format as a seamless map image. Map projection is Equirectangular/Geographic/Geodetic/Plate Caree - best suited for measuring position and for use in conjunction with GPS. 1:1,000,000 scale maps and 50m Landsat satellite image are also included.

  • This mosaic comprises 165 scenes that were acquired between November 2000 and February 2001 from the RADARSAT satellite. This satellite carries a radar instrument that sends pulsed signals to Earth and processes the reflected pulses. The information received by the satellite is converted into a black and white image that shows the texture of the Earth"s surface in a different way to a normal "photograph". The poster is about 91cm x 80cm and is at 1:5,500,000 scale.

  • The Landsat series of satellites commenced acquiring remotely sensed data with the launch of Landsat 1 in 1972. Landsat satellites travel at an altitude of 705 kilometres and provide coverage of the entire globe every 16 days. Landsat 7, launched on 15 April 1999, carries the Enhanced Thematic Mapper Plus (ETM+). As the name suggests, the ETM+ sensor is similar to the TM sensor but has some added features. It provides imagery in the same seven spectral bands as the TM sensor with 30 metre resolution, but has an added panchromatic band with 15 metre pixel resolution. ETM+ also has an enhanced thermal band with a 60 metre resolution. Its ground swath is 185 kilometres. A full scene is approximately 184 kilometres by 172 kilometres. The archive of ACRES products includes ETM+ data from 6 July 1999 onwards.
