I have to process a bunch of files and keep doing the same tasks with each file. So, I thought..write a program in ENVI Modeler to do the rescale, remove bad bands, and atmospheric correction. Well, easier said than done. How do I do the band math option where I apply the same scale factor to each of the 421 spectral bands? I know how to do it manually, but it seems that the band math module in ENVI modeler does not give me the option to apply the band math expression to all spectral bands. Is that correct or is there another way to do this? Thanks.
