3D Elevation Program (3DEP)

3D Nation Subcommittee

The goal of the 3D Nation Elevation Subcommittee established in 2016, unites terrestrial and coastal/ocean mapping agencies for the coordination and integration of terrestrial and bathymetric elevation mapping.

The focus is on improving the national mapping foundation by Federal agencies members in the 3D Elevation Program (3DEP), the Interagency Working Group on Ocean and Coastal Mapping (IWG–OCM), and partners of other Federal, State, academic, and private sector groups. The subcommittee seeks to ensure access to an accurate, updated, continuous elevation surface from the land to the coasts to the depths of our oceans. The concept of a 3D Nation serves as a unifying goal for these efforts, providing a consistent set of standards and objectives for an authoritative National geospatial foundation.
