I have an .asc grid file that I would like to be able to clip, convert to an ESRI grid, and also use the Set Null tool on. However, when I try to use any of these tools, the Values in the grid file change. I am so confused. For example, in the original .asc grid file, the max value is 1.478. When I run a the Clip too, the max comes out at 5.8928. All the cell values change (and it isn't applying a meters to feet conversion, I checked that out). Has anyone run into something like this?
