Abstract: In order to derive the distribution of olivine and pyroxene in Crater Copernicus, we compute two band ratios (950/750 and 2 000/1 500 nm), percent content of elements (Al%, Ca%, Mg%, FeO%) and maturity (Is/FeO) based on Clementine UVVIS and NIR image data. The central peaks of Copernicus, which are known to be olivine-rich or pyroxene-rich, are chosen as “ground truth” and ROIs used to derive the distribution of olivine and pyroxene with a decision tree and spectral angle mapper (SAM). Additionally, we compared previous works and the extraction results coming from the decision tree and the SAM method...
