Geological Assessment of SIR-B Imagery of the Amadeus Basin, N. T., Australia

When SIR-B imagery of the arid margin of the Simpson Desert of Central Australia is combined with Landsat MSS principal component data, regional geological structures are clearly defined. A variety of sedimentary lithological units are mapped on the basis of outcrop morphology and MSS spectral variations on the color-Composite image. Relative backscatter power from SIR-B digital imagery is observed to correlate with surface roughness for a variety of lithological terrains.
