https://community.esri.com/t5/arcgis-pro-questions/classify-las-ground-issues-with-number-of-returns/m-p/1379869#M78489 <P>I have a point cloud I am trying to classify, however the classify ground yields poor results. It seems that within my point cloud every point has a return of "x of 3", the only points classified as ground are 3 of 3, whereas areas of unobstructed ground are not classified, and on inspection they have a return of 1 of 3. I believe their return should be 1 of 1, and this is potentially why the tool is not classifying correctly. This seems like this could be an issue with the sensor not recording all this information.&nbsp;</P><P>Does this seem like the cause of the problem, and does anyone have a way to work around this? Or extract the correct number of returns from each pulse?</P><P>Thanks</P> Thu, 08 Feb 2024 17:54:13 GMT PatrickDroste1 2024-02-08T17:54:13Z https://community.esri.com/t5/arcgis-pro-questions/classify-las-ground-issues-with-number-of-returns/m-p/1379869#M78489 <P>I have a point cloud I am trying to classify, however the classify ground yields poor results.
