3D Elevation Program (3DEP)

Contribute Data

Does your organization have lidar data that you would like to contribute to The National Map?

The USGS National Geospatial Program will evaluate these datasets for completeness and suitability in meeting 3DEP program goals and objectives. The data must meet the USGS Lidar Base Specification before publication in The National Map.  The USGS 3DEP Elevation Specifications Review Board (ESRB) is responsible for updates to specifications and requirements for elevation products used in The National Map.  Only data that is offered to USGS free of charge and without use restrictions can be considered. 


If your organization is interested in contributing lidar data, please contact the National Map liaison for the state in which the lidar survey is located. The National Map liaisons can provide more information and assist you with the process of contributing data.  Please see the points of contact on the National Geospatial Program User Engagement website at: https://www.usgs.gov/about/organization/science-support/ngp-user-engagement-office/connect
