Please make sure you have installed ArcGIS pro patches.&nbsp;</P><P></P><P>Failing to creat overviews might be something to do with files and permissions. Can you open mosaic dataset after loading DEM's and view it on ArcGIS pro?&nbsp;</P><P></P><P>Cheers,</P><P>Hamed&nbsp;</P></BODY></HTML> Tue, 22 Sep 2020 02:24:30 GMT https://community.esri.com/t5/arcgis-pro-questions/mosaic-dataset-failed-connection-to-local-worker/m-p/693751#M30721 HamedFarzin 2020-09-22T02:24:30Z Re: Mosaic dataset failed - Connection to local worker service lost? https://community.esri.com/t5/arcgis-pro-questions/mosaic-dataset-failed-connection-to-local-worker/m-p/693752#M30722 <HTML><HEAD></HEAD><BODY><P>Thanks Hamed,</P><P></P><P>so based on that info above, I changed the parallel processing factor to blank instead of 70 and the process worked...</P><P>to answer your question though I could end up opening the DEM mosaic dataset in pro - i just had to manually build the overviews and statistics/histogram.&nbsp;</P><P></P><P>looks to be all good now, thanks for your help <IMG src="https://community.esri.com/legacyfs/online/emoticons/happy.png" /></P></BODY></HTML> Tue, 22 Sep 2020 04:10:21 GMT https://community.esri.com/t5/arcgis-pro-questions/mosaic-dataset-failed-connection-to-local-worker/m-p/693752#M30722 xaviermurray 2020-09-22T04:10:21Z
