Hight error values can be found in areas with steep slope and close to waterbodies and are caused by sensor shadowing. I would like to find those height errors and replace those values with data from my reference layer.&nbsp;</P></BODY></HTML> Mon, 30 Mar 2020 11:47:20 GMT https://community.esri.com/t5/arcgis-pro-questions/how-can-i-detect-hight-errors-in-a-dsm-in-hight/m-p/306025#M13308 MelinaHager 2020-03-30T11:47:20Z Re: How can I detect hight errors in a DSM in hight mountain areas https://community.esri.com/t5/arcgis-pro-questions/how-can-i-detect-hight-errors-in-a-dsm-in-hight/m-p/306026#M13309 <HTML><HEAD></HEAD><BODY><P>You will need some criteria to identify them in order to remove them</P></BODY></HTML> Mon, 30 Mar 2020 12:53:01 GMT https://community.esri.com/t5/arcgis-pro-questions/how-can-i-detect-hight-errors-in-a-dsm-in-hight/m-p/306026#M13309 DanPatterson_Retired 2020-03-30T12:53:01Z
