Hello. I ran the Compute Difference Map on a couple TM images to do a basic land cover change analysis (after atmospheric correction). I did this for the vis green, red and NIR bands. Is there a way to get any statistics behind the resulting change maps? Similarly, how can I combine this image differencing method with the post-classification change analysis method to get a really intuitive analysis and possibly compare and contrast the two approaches for my dataset and study region? Many thanks.
