DEM, in particular, in urban areas.</SPAN><BR /><BR /><SPAN>However, if your DSM is referred to the data model in engineering/geomatics literature, which is constructed from 0.8-m optical data (stereo-pair imagery, or LiDAR cloud points), accurate 'bare' DEM (and/or 3D city model) can be automatically classified by advanced algorithms within remote sensing packages like Leica LPS or TerraScan, ...</SPAN></BODY></HTML> Sun, 03 Nov 2013 03:49:59 GMT https://community.esri.com/t5/data-management-questions/how-to-convert-a-dsm-to-dem/m-p/241800#M13747 larryzhang1 2013-11-03T03:49:59Z Re: How to convert a DSM to DEM https://community.esri.com/t5/data-management-questions/how-to-convert-a-dsm-to-dem/m-p/241801#M13748 <HTML><HEAD></HEAD><BODY><P>Use SimActive DSM to DTM module..</P></BODY></HTML> Wed, 13 Jun 2018 13:55:27 GMT https://community.esri.com/t5/data-management-questions/how-to-convert-a-dsm-to-dem/m-p/241801#M13748 leostalin 2018-06-13T13:55:27Z
