I currently have a DEM for an east coast city. Unfortunately, the elevation of an area containing a Dam is not accurate. I have the correct elevations as reported by the city. How would I go about editing the elevation values of a specific group of cells so that they accurately reflect the elevation difference of the dam?
I need to find a way to select a subset of the nearby DEM cells and edit them so they are accurate with the dam heights.
How do I do this using ArcGIS Desktop?
