GEOLOGICAL MAPPING OF PROTEROZOIC BASEMENT OF IGUERDA-TAYFST INLIER (CENTRAL ANTI-ATLAS, MOROCCO), BASED ON THE INTERPRETATION OF THE DIVERGENCE OF SPECTRAL INFORMATION

The contribution of Remote Sensing for Geological Mapping of Proterozoic basement of Iguerda-Tayfst, is endowed by the large spatial and spectral resolution of ASTER data. In particular, spectral analysis of this dataset has demonstrated great effectiveness in the discrimination and mapping of extensive geological units forming this inlier. The DIS algorithm classification (the divergence of spectral information), is used in this study to improve the abundance limited information filtered by the two methods SAM (spectral angle mapper) and MMV (method ofmaximum likelihood). However, the product of this classification is more accurate and close to the baseline, with their ability to capitalize on improved information ASTER spectral data, useful for geological mapping in arid regions.
