The 3D Elevation Program (3DEP) products and services available through The National Map consist of standard digital elevation models (DEMs) at various horizontal resolutions, and elevation source (lidar) and associated datasets. In , Digital Elevation Models were migrated to the Cloud Optimized Geotiff (COG) format. The USGS Digital Elevation Model (DEM) data files are digital representations of elevation information in a raster or grid form. DEMs consist of a sampled array of elevations for a number of ground positions at regularly spaced intervals.  · Download for free Digital Elevation Model (DEM) of 12 metres resolution Febru by franzpc A fairly common problem is usually the access to spatial information, in this case Digital Elevation Models (DEM) are not always available to everyone, either by cost, availability, or lack of knowledge to obtain them.
