Hello, I am a fourth year Geology student, and for my research project I am doing a comparison of Martian and Terran Alluvial Fans. I'd like to use CRISM data to display the mineralogy of fans in craters. However, the way I was planning on doing this was using ArcMap to show intensity of pixels in bands. I'm not sure if this is a valid methodology and I'd appreciate any advice on how to go about displaying mineralogy. I understand that analysis can be done using ENVI, but I've not had any experience with this. I would also say I'm just about competent in using ArcMap.
