Wladimir Acevedo Posted May 26, 2019 Share Posted May 26, 2019 Hi dear community, I'm starting with the CRISM data processing with ENVI 5.3 + IDL + CAT 7.4 but for now i feel a few lost, altough i keep the adventure. In any case, i have a couple of questions (very basics, probably) for the TRDR images from the CRISM map data center. 1.- Why when i open the trr3 images with CAT it appears as a rectangle (img_1) and not compressed or deformed like the images that i've seen in papers or documents? additionally it opens inverted so i have to apply a 180° rotation. 2.- When i open the images the band 1 has a value of 65535.0 (img_2)! and that carries problems when i want to visualize the spectral plot. So, it is recommended to eliminar this band or i'm doing something wrong with the images treatment? Any kind of help will be very useful, since i'm really new on this.
