    Hello All, I want to combine set of classifed images into a single image. For eg: If image1 class is "A" AND image2 class is "B" then output image class is "C". I looked at band math but I guess another approach is neccesary for combining classified images. Any help is appreciated. Regards, Sitansu

    Not exactly sure what you're doing, but I'd think either masking (finding intersection of classes) or the Decision Tree classifier in ENVI 4.0 would be your best bet. If it gripes about the input files being of Classified type, just change it to ENVI Standard in the header then switch it back to classified when you're done.
