High quality elevation data are critical to flood risk management, infrastructure management, resource management, conservation, energy, agriculture, and a host of other nationally significant applications. The primary goal of the 3D Elevation Program (3DEP) is to systematically collect three-dimensional (3D) elevation data in the form of high-quality light detection and ranging (lidar) data over the conterminous United States, Hawaii, and the U.S. territories; and interferometric synthetic aperture radar (IfSAR) data for Alaska, where cloud cover and remote terrain limit lidar acquisition. 3DEP is based on the results of the National Enhanced Elevation Assessment (NEEA) that documented the business uses of 34 Federal agencies, 50 states, and several local, tribal and industry representatives. 3DEP is a cooperative program led by the U.S. Geological Survey (USGS) and includes many partners from State, Tribal, and local governments who are working together to complete nationwide coverage in 8 years. The program has placed a major emphasis on developing partnerships among Federal and state agencies, and creating effective interagency governance organizations (the 3DEP Executive Forum and the 3DEP Working Group) to guide the development of 3DEP and to solicit input on the program from outside of USGS.


To facilitate executive dialog and collaboration on strategies to implement and sustain 3DEP for the benefit of its Federal stakeholders and the broader community.


  • Develop plans and coordination actions for 3DEP implementation and monitor the status of the program.
  • Track and coordinate on significant developments regarding elevation or related geospatial activities – for example, actions being taken to address legislation, hurricane supplemental funding, GAO reports or other multi-agency activities.
  • Share insights and develop strategies to communicate with industry and other potential stakeholder groups that could play a role in 3DEP funding.
  • Provide executive direction and input to the 3DEP Working Group as the operational coordinating body for enhanced elevation.
