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.

Geoscience Australia, ACRES distribute Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data for a series of epochs or time frames covering Australia. The first epoch is 1972. These data have been produced and provided by the Australian Greenhouse Office (AGO). AGO use the data in their National Carbon Accounting System for monitoring land clearing and revegetation. This data is only available through ACRES and ACRES Landsat Distributors, and not through the AGO. More information is available at <a href="http://www.ga.gov.au/acres/prod_ser/agosuite.jsp">http://www.ga.gov.au/acres/prod_ser/agosuite.jsp</a> This data is available in 1:1M tiles or as a full continental Mosaic. Tiles areas are available at: <a href="http://www.ga.gov.au/acres/prod_ser/agotilemap.jsp">http://www.ga.gov.au/acres/prod_ser/agotilemap.jsp</a>

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.

The Perth study is part of Infoterra's Global Seeps programme - a multi-phase two year exploration programme to create the definitive offshore seeps database for the worldwide exploration industry. The North Perth Basin study contains interesting indications of active petroleum systems. The study results support the renewed interest in the Perth Basin as a result of the recent exploration success at Cliff Head-1.

More than 100 bushfires raged across NSW from 25 December 2001 - January 8 2002, requiring over 20,000 regular and volunteer fire fighters and 85 aircraft. Vast stretches of forests were destroyed, including more than 60% of the Royal National Park. More than 11,000 people were evacuated from their homes and 560,000 hectares were burnt out. The image below was acquired from the SPOT satellite on 27 December 2001 by ACRES, Geoscience Australia. It is produced here as a mosaic of 8 SPOT scenes covering about 120km wide and 240km long, stretching from Wyong in the north to Jervis Bay in the south. Healthy vegetation shows as bright red, forest as dark red, ocean and lakes as dark blue, burnt areas as black and smoke as blue/white.

These datasets are a subset of the mosaic of Australian Landsat MSS images of Australia. ldsatmss.bil is a 500m pixel Lambert Conformal Conic projected dataset. ldsatmssdd.bil is a 0.0048 degree geographic projected dataset. NOTE The original image is located in the corporate storage system at /d/geo/store/data/image/landsat_mss/aus_mosaic. In this directory there is extensive documentation (OVERVIEW.TXT) which describes all contents.
