3DEP Product Standards

Products of the 3D Elevation Program are built upon the most current applicable standards for geospatial data. In particular, the foundation for the 3DEP standard DEMs is an assembly of digital elevation models that conform to USGS National Geospatial Program standards. Standard DEM updates generated from new light detection and ranging (lidar) acquisition projects meet, at minimum, specifications defined in the USGS lidar Base Specification (

3DEP products are documented using the Federal Geographic Data Committee (FGDC) content standard for geospatial metadata. 3DEP products are searchable collections through the Open Government Initiative. Elevation products are provided in formats that are fully compliant with Executive Order 12906, OMB Circular A-16, OMB Circular A130 , and OMB Circular A-119.

If you encounter problems or require more information about these standards, please contact National Map Help.
