Hi, I'm working with ENVI 4.5. I create 7 classification bands (images). Every class have his own image(band). I want put together them in one band(image) and keep the class name and number! Could you suggest something? I tried Band math. Result, all classes have the same value. I tried to multiply every class band by class number, not work, i think the reason is that the class band is in byte format. I tried sum class number, it works but background is (class number minus 1), then i mask out class and say that the background to 0, again not work. I checked help, nothing. Maybe i am to stupid. Overly tool do not work in the way i want.
