A new approach for discriminating calcite and dolomite by ASTER imagery in arid and semi-arid regions

The supplementary zip file contains several files and folders. There is a pdf file inside the zip file which describes where each file can be found. <br>These data include, but are not limited to the following items:<br>- The ArcGIS shapefile (.shp) which shows the study area;<br>- The classification map produced by the mapping method introduced in the article for classifying carbonate rocks into dolomite and calcite in the study area (in shapefile format);<br>- A lithologic map of the study area (in shapefile format);<br>- The high-resolution spectra of rock samples collected during fieldwork (in ENVI spectral library format);<br>- A compilation of the spectral materials downloaded from ASTER spectral library (in ENVI spectral library format). These spectra include that of dolomite, calcite, limestone, dolostone, epidote, vegetation, shale, and soil.
