How to compare two DEMs to see vertical differences
Can someone help me figure out how to compare two dems to see where vertical changes have happened? I know there is a really simple way to do this, but I cant seem to get it to work.

Hello,
Just use the Terrain Analysis -> Combine/Compare Terrain menu command to subtract one loaded DEM from another to get a difference surface.
Thanks,
