Soil and Rocks Minerals Mapping from ASTER Imagery using Spectral Angle Mapper and Spectral Library

Описание: How to perform minerals identification and classification of rocks and soil using spectral angle mapper classifier and ENVI software. This demo applied using ASTER imagery, however it is can be extended to Landsat or Sentinel Imagery. Works better in open terrain such as arid or desert region with minimum to none of vegetation cover.

Surface reflectance data (atmospherically corrected) is mandatory for the best result. Field inspection also mandatory to assess the classification accuracy because SAM is very sensitive to different parameter settings.
