    Hello all,
    I have 2 images of the same are taken before and after a natural disaster. I converted them to NDVI images and now I want to see the differences between the 2 NDVI images to see where and how much changes occurred. I know I need to use band math, but not sure how to do it.

    Can anyone help?

    Thank you
