How do you perform DEM subtraction? once you fill a DEM, how can you subtract the original DEM from the filled DEM?
Mapping Center Answer:
Use the Minus tool (use the Index tab in the Toolbox window--start typing Minus and it will show up). Input would be your filled DEM and the second parameter will be the original DEM.
