3D Elevation Program (3DEP)

Collaboration and Partnerships

Partnership Opportunities 

The FY19/FY20 Broad Agency Announcement (BAA) for 3D Elevation Program (3DEP) is scheduled for release in September 2019. The BAA provides detailed information on how to partner with the USGS and other Federal agencies to acquire high-quality 3D Elevation data. After release, information and contacts will be available at Fed Biz Opps and Grants.gov. Applicants may contribute funds toward a USGS lidar data acquisition activity via the Geospatial Products and Services Contracts or they may request 3DEP funds toward a lidar data acquisition activity where the requesting partner is the acquiring authority. Federal agencies, state and local governments, tribes, academic institutions and the private sector are eligible to submit proposals. Information on previous Broad Agency Announcements and awards can be found here.

► Questions on the BAA can be submitted to gs_baa@usgs.gov


3DEP Federal Best Practices 

Successful implementation of the 3D Elevation Program (3DEP) depends on the development and adoption of a unified Federal approach to acquiring data. The purpose of this document is to outline several best practices to aid the Federal 3DEP community in reaching a higher level of coordinated implementation, maximize Federal data investments, and to reduce the number of years it will take to complete national coverage. The best practices are provided to Federal agencies as a check list to assess the level of their participation and to inspire further adoption of Federal enterprise practices that will advance joint 3DEP coverage goals for the benefit of their missions and the Nation as a whole. It is anticipated that additional best practices will be defined and added as the effort matures.

Public Webinars

The USGS hosts a public webinar each year to introduce the BAA opportunity to the broadest stakeholder community possible and to provide a summary of the application process.   The public webinar for the FY19/FY20 BAA will be held August 7, 2019 at 1:00 PM (EST).

► More information, including how to register, can be found on the FY19/FY20 Broad Agency Announcement web page.

The U.S. Federal Mapping Coordination website

A collaboration site for Federal and partner mapping data acquisition (Seasketch).

The United States Interagency Elevation Inventory (USIEI)

The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and National Oceanic and Atmospheric Administration with contributions from the Federal Emergency Management Agency, U.S. Department of Agriculture, and U.S. Army Corps of Engineers. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and Fall.


  • Provides an index of elevation data
  • Includes both topographic and bathymetric data and covers the entire nation
  • Allows users to query by county or zoom to an area of interest and print a report

National Oceanic and Atmospheric Administration (NOAA) Digital Coast

The Digital Coast provides tools, training, and information needed to turn geospatial data into information used by coastal resource managers.
