I have tried to change the classification codes, but the heights are too similar that it will classify buildings as ground.&nbsp;I have tried changing the classification codes, building a DSM, DTM, nDSM, but I have no polygons to extrude the buildings.</P><P></P><P>What are different ways to make lidar point cloud data 3D?</P></BODY></HTML> Mon, 23 Jul 2018 13:29:32 GMT https://community.esri.com/t5/3d-questions/how-to-get-from-lidar-point-cloud-to-3d/m-p/40808#M292 AlejandraEspinosa 2018-07-23T13:29:32Z Re: How to get from Lidar point cloud to 3D? https://community.esri.com/t5/3d-questions/how-to-get-from-lidar-point-cloud-to-3d/m-p/40809#M293 <HTML><HEAD></HEAD><BODY><P>What is the horizontal and vertical projections of you lidar data?&nbsp; &nbsp;It might be the xy is in geographic coordinates and the elevation is in meters or feet.&nbsp; &nbsp;If so, you could use Extract Las and set in the environments to be a different projection for the horizontal projection.&nbsp; &nbsp; I have run into this with one of the lidar datasets I processed into extract building footprints from.</P><P></P><P>Arthur Crawford - Esri Content</P></BODY></HTML> Wed, 22 Aug 2018 13:50:25 GMT https://community.esri.com/t5/3d-questions/how-to-get-from-lidar-point-cloud-to-3d/m-p/40809#M293 ArthurCrawford 2018-08-22T13:50:25Z
