Spectral information from computer enhanced TM-Landsat 5 data were evaluated within the context of lithological limits discrimination in the Crixas Greenstone Belt, State of Goias, Brazil. Several digital enhancement techniques were applied including: (1) Linear contrast strech; (2) Streched Band Ratio; (3) Decorrelation; (4) Principal Component Transformation and (5) IHS Transformation. These techniques allowed to emphasize sutil spectral differences. The resulting images are exceptionally well correlated with the lithological units mapped by conventional methods in 1:100,000 scale. |
