Application of radar and optical remote sensing data in lithologic classification and identification

In order to verify the supplementary effect of radar remote sensing on optical remote sensing in geological applications, an experimental study on the use of fully polarimetric radar data for lithologic classification is carried out. First, the ASTER data are used to classify the lithology, and then the ASTER and RadarSAT-2 data are superimposed on the lithology classification, and the results are quantitatively evaluated by the existing regional geological survey map. The results show that the total polarization SAR images can be superimposed on the optical images, which can effectively improve the accuracy of lithologic classification.
