Brief description
The National ASTER project is the culmination of a successful collaborative initiative, led by CSIRO’s Western Australian Centre of Excellence for 3D Mineral Mapping (C3DMM) and Australian State, Territory and Commonwealth government geological surveys, as well as international partners in Japan and the USA.
The ASTER Geoscience Maps of Australia are the first public, web-accessible continental-scale maps of the Earth’s land surface mineralogy. A toolbox of 17 national geoscience maps is now available for use by explorers, researchers and the public, showing surface mineralogical information across the whole of Australia.ASTER’s 14 spectral bands provide sufficient spectral resolution to measure the broad content and composition of mineral groups (e.g. Al-bearing clays, carbonates and silicates), in a world-first continental-scale mosaic.
