HyVista Corporation was contracted by PIRSA to process HyMap airborne hyperspectral scanner data of the Earth's surface acquired during December 2000 from a survey window covering ~1100 sq km of the Musgrave Ranges in South Australia. The HyMap instrument is an airborne hyperspectral scanner delivering 126 bands (approx 18 nm width per band) of imagery over the 450 nm to 2500 nm spectral interval. HyMap image data pre-processing is carried out on a survey flight line strip-by-strip basis, to produce radiance, apparent reflectance, and GLT (Geometric Lookup Table) files for later geometric rectification/mosaicing. The apparent reflectance images are corrected for cross-track and signal level (i.e. they are corrected for varying solar illumination). These reflectance images are then geo-corrected, to position each individual pixel in its accurate geo-location in the UTM/WGS 84 map projection. The corrected image data survey strips are then mosaiced to produce a seamless, homogeneous data (map) cube for the whole survey area (a step called 'Level 1C processing'). This data-cube is then processed further to produce the various Level 2 and 3 image products (Decorrelation Stretch RGB [red-green-blue], Mineral Map Multimineral Rule Classified, Mineral Map Ternary RGB, Mineral Maps Pseudocolour, Mineral Map Greyscale Threshold, MNF [Minimum Noise Fraction algorithm] Transform RGB, Overview Colour Composites (in both true and false colour), and Wavelength Mapping - Mineral Chemistry and Composition). The last type of processed image includes three separate products designed to depict either mica Al content, iron oxide composition or carbonate Mg/Ca ratio-composition.
