Hello, I'm involved in a research project using ENVI 5.3 and CAT 7.4 for processing CRISM data (hyperspectral Mars images). I was wondering if is possible to automatize in some manner the mineralogy per pixel and export that information to an excel table. I haven't information if this is possible or if some similar has been done on hyperspectral analysis works on Earth. Thank you.

I am not familiar with the tools in CAT 7.4 - does this tool have a 'minerology per pixel' tool? A tool that will separate materials at the sub-pixel level in ENVI would be something like Linear Spectral Unmixing. Is this what you are looking to do? If so, there is the routine: http://www.harrisgeospati...ralunmixingtask.html Then, after you calculate the results, you can export the resulting raster to ascii using File->Save As->Ascii.
