This option converts built-in lidar data to a Digital Elevation Model (DEM) in a specified resolution for download in geoTIFF format. The DEM only includes lidar points with a “ground” classification – i.e. bare earth.

DSM (geoTIFF)

This option converts built-in lidar data to a Digital Surface Model (DSM) in a specified resolution for download in geoTIFF format. The DSM includes all point classifications, including built and artificial surface features (trees, buildings, etc.) 

Point Cloud
