Thanks for the reply. Forgot to mention that the images are basically "tiles" that together create a map of a municipality. They don't actually "stack" on top of each other. Basically like a puzzle, got several pieces and I'd like to create only 1 piece, so then I can run all my analysis onto that 1 image file. Otherwise I cannot do classification with ROI's from different images (at least the tool only allows me to select 1 image from what I noticed). I only have ENVI to work with, and cannot find a way to either "glue them together" or run analysis using each separate images into each analysis I want to run (in my case, supervised classification)

I am looking to "combine" several hyperspectral images I have into 1 image. Reason being is that I want to create ROI's in order to do supervised classification. However, these training areas must be from several images. I need to basically create 1 ROI classified as "good", another ROI as "bad" and the 3rd I'l have everything else. Not sure how to do this unless I somehow combine all images into 1. ENVI 5+ is nice and you can open all the images into 1 window, and they kind of look combined, but when you do the ROI's, they are still separated into each image.
