Trying to use the Spatial Analyst "Minus" tool and cannot get it to function properly. My basic system is:
ArcGIS 10.1 SP1 (Build 3143)
Windows7 Enterprise SP1
I have two grids, one of which I am trying to subtract from the other. I can display both and generate contours from both so I am assuming there are no gross errors in the data. When I bring up the tool bar, select Minus, fill out the three parameters and hit OK, I get the following results. Any help in resolving this will be greatly appreciated.
