Free imagery for Western Australia
There is new free imagery for Western Australia that will be of great use for mining and exploration industry: Satellite ASTER Geoscience Map of Western Australia. Quoting from media release, “ASTER, Japanese imaging instrument flying on the US TERRA satellite, launched in December 1999, has 14 spectral bands spanning wavelengths sensitive to important rock forming minerals, including: iron oxides, clays, carbonates, quartz and “Hydrothermal” minerals such as muscovite and chlorite.” “ASTER geoscience maps provide new mineral information not available from other current technologies. This new mineral information is valuable for more accurate mapping of the regolith cover that blankets much of Australia and finding those often small islands of bedrock materials, such as greenstones that may be associated with gold.” downloaded for free in JPG2000 GeoTIFF format from CSIRO. The complete data set (~500 Gigabytes), is available from Geological Survey Western Australia product sales.
