The problem is that for the first DEMs it works But the last one keeps giving me this error: ERROR 999999: Error executing function Failed to execute (Nibble). I tried in both ModelBuilder and manually and I still get the same error. It occurs during the initialization phase, which indicates there is something wrong there. I do not know what is wrong. Can anyone please explain what is wrong?</P></BODY></HTML> Sat, 05 Oct 2019 22:34:52 GMT NathanFleischman 2019-10-05T22:34:52Z ERROR 999999: Error executing function Failed to execute (Nibble) https://community.esri.com/t5/arcgis-spatial-analyst-questions/error-999999-error-executing-function-failed-to/m-p/332607#M4665 <HTML><HEAD></HEAD><BODY><P>I am trying to use the Nibble tool to clean NoData in three Digital Elevation Models.

The other thing to check is whether the input DEM is integer.</P></BODY></HTML> Mon, 14 Oct 2019 01:29:10 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/error-999999-error-executing-function-failed-to/m-p/332608#M4666 curtvprice 2019-10-14T01:29:10Z Re: ERROR 999999: Error executing function Failed to execute (Nibble) https://community.esri.com/t5/arcgis-spatial-analyst-questions/error-999999-error-executing-function-failed-to/m-p/332609#M4667 <HTML><HEAD></HEAD><BODY><P>To me It&nbsp;often happens when I do not save my output in a geo database.&nbsp;</P></BODY></HTML> Sat, 14 Mar 2020 21:38:09 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/error-999999-error-executing-function-failed-to/m-p/332609#M4667 AbdulMajid 2020-03-14T21:38:09Z
