https://community.esri.com/t5/3d-questions/las-dataset-vertical-units/m-p/1205417#M4797 <P>Hello! I am relatively new to working with las datasets. I have a local scene setup and was wondering why my las dataset is showing vertical units as undefined? Each point in the point cloud seems to have the proper elevation. Do I need to define a vertical coordinate system? I would appreciate any insight, thank you!</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="EliasRex_0-1661266367142.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/49192i741B9E41F791F082/image-size/medium?v=v2&amp;px=400" role="button" title="EliasRex_0-1661266367142.png" alt="EliasRex_0-1661266367142.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="EliasRex_1-1661266381873.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/49193i7979E78ABA07843C/image-size/medium?v=v2&amp;px=400" role="button" title="EliasRex_1-1661266381873.png" alt="EliasRex_1-1661266381873.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="EliasRex_3-1661266821841.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/49195iA768ED3F66D7FBF9/image-size/medium?v=v2&amp;px=400" role="button" title="EliasRex_3-1661266821841.png" alt="EliasRex_3-1661266821841.png" /></span></P><P>&nbsp;</P> Tue, 23 Aug 2022 15:01:00 GMT EliasRex 2022-08-23T15:01:00Z https://community.esri.com/t5/3d-questions/las-dataset-vertical-units/m-p/1205417#M4797 <P>Hello!

If you don't already know, there is a geoprocessing tool called Define Projection that will define the vertical coordinate system. It looks like you are working in state plane, so I believe you would select&nbsp;NAVD88_height. This is a late response but I hope this helps!</P> Tue, 20 Sep 2022 14:47:12 GMT https://community.esri.com/t5/3d-questions/las-dataset-vertical-units/m-p/1214202#M4815 SaraJCourter 2022-09-20T14:47:12Z
