Hello everyone, I've been working with a set of stacked layer MODIS tiles in ENVI and have been trying to write an IDL program to do some batch processing for me. I'm stuck on two areas. First, I haven't found a way to read the layer stack into IDL. To clarify, I have one file that contains a data cube consisting of many MODIS tiles overlaying one another. I tried using ENVI_OPEN_FILE, stackfile but according to my log that didn't actually open the file. My second challange is that I haven't been able to find an ENVI command that allows me to create a Z-profile (specifically, I'd like to us lat/long coordinates as input data). Once the Z-Profile is created the data needs to be exported as an ASCII file (or possibly saved into an array, which can then later be exported?). Thanks, - Max
