Abstract

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.
