| 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 ... |
