I converted those to .LAS files using the Create LAS tool. I then created hillshade files form there using the Create LAS Dataset tool. The product from that is shown in the image above.&nbsp;</P><P>Is there a way to smooth or exaggerate the elevation so I can determine the elevation of specific areas? Does this DEM appear correct and it is just picking up on the microtopography of the floodplain? The portions of "blobs" in the elevation are of water bodies. Thank you for helping.&nbsp;</P> Thu, 04 Nov 2021 20:14:08 GMT https://community.esri.com/t5/arcgis-pro-questions/create-smoothing-for-dem/m-p/1114287#M47582 ClaireMcHenry 2021-11-04T20:14:08Z https://community.esri.com/t5/arcgis-pro-questions/create-smoothing-for-dem/m-p/1114781#M47608 <P>Could the surface roughness be a result of your model including more than just ground returns?&nbsp; If you DEM included vegetation Lidar classes t could look a bit like that, in which case, you've created a vegetation DSM?</P> Mon, 08 Nov 2021 01:44:05 GMT https://community.esri.com/t5/arcgis-pro-questions/create-smoothing-for-dem/m-p/1114781#M47608 MicZatorsky_AEC 2021-11-08T01:44:05Z
