I am getting error while running Viewshed2 tool in ArcGIS 10.3.1 using SRTM 90m data. It is giving error code 010462 which says Geodesic visibility exception; can not create HashedRowCollection snapshots file. Any solution
Just reading through the help file, the following caveats are listed:
Could any of these apply to your case?
I have the same problem than Sovan. I have checked there is a CUDA GPU and set the Tdr delay to 60 as recommended in the tool-help. First Error-Message was a litte different. After setting a vertical coordinate system to the observer points it is just the same as above. But I´am failing in advising a vertical coordinate system to the input raster-DEM. Any ideas how to do this? I hope this will solve the problem.
@Jim - there is more than 30GB free space on the temp drive, and the error comes just after starting the tool. I doubt there is any connecting, because i am testing with reduced resolution and simplified data.
Are you still getting this error? How much temp space do you have on the drive where your ArcGIS temporary folder is located?
