So I have been trying to figure this one out for ages but I just can't seem to do it.
I have 2 rasters. One representing terrain and the other representing an interpolated surface which is beneath the ground.
The interpolated layer is greater than ground level in some places, which in reality is impossible. I need to make the interpolated layer equal to the ground surface layer where it has a greater elevation than the ground surface.
It looks like this in profile view
How can I do this..?
