Hi all,

I had this same issue. I followed all the advice above related to file paths, character length and type, etc.  I solved the issue following the advice here.  I exported the raster from being geodatabase-hosted to being stand alone GRID in a separate folder.  I was then able to run the Depression Evaluation tool successfully.

My first time seeing this topic. Have not used the Depression Evaluation tool. * The message "Could not reference the raster dataset." makes me wonder if the processing extent is covering project area. I once had a tool change the processing extent and not change it back. So everything worked fine until I got past that step, then raster results would get trimmed to the new extent. I've learned to keep and eye on the extent. ** I've seen python code the saves the current processing extents, changes them, does some processing, and then recalls the saved extents. # Save the extent environment tempEnvironment = arcpy.env.extent # Set the extent environment using a keyword. arcpy.env.extent = "MAXOF" ... ... # recall extent arcpy.env.extent = tempEnvironment‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ * I agree with the naming rules. Seeing the "~" in the file name in the original post (C:\USERS\PMH\APPDATA\LOCAL\TEMP\ARCF98B\AH2016~4\G_G2432) reminds me of file names that were too long for the old 8 character limits of long ago. I suspect (I don't really know) that some routines still have that limit and I try to keep file names and directory names short (at least those that would go through geoprocessing - rasters especially). ** If someone knows how to display the processing extent on the map (if only temporarily or as graphic) that would be nice. I hate simply resetting the processing extent as a "solution" when I'm not sure if it is the problem.

Hi,

I was wondering if this problem is resolved? I am running into the same problem running the Depression Evaluation tool.

Thanks!
