I have created a phase to displacement map for a volcano in Russia. I want to remove all pixels that are less than a certain elevation so that I’m left with just the volcano as I’m not interested in the surrounding area and don’t want these pixels to be included in the histogram. Is this possible?
You either define a valid pixel expression in the band properties (e.g. elevation > 350) or you create a mask in the band maths (same expression) and use it to remove the pixels (e.g. by multiplying the mask with the displacement, sets all unwanted pixels to zero).
please let us know which method you selected and if it works for your case (maybe with a screenshot), so others can learn from your example.
