Partnership Opportunities 

Partnership Icon, shaking hands

The FY19/20 Broad Agency Announcement (BAA) for 3D Elevation Program (3DEP) was released September 9, 2019. Information and contacts are posted to Fed Biz Opps (Reference Number 140G0119R0029) and to Grants.gov (Opportunity Number G19AS00124).  

The BAA provides detailed information on how to partner with the USGS and other Federal agencies to acquire high-quality 3D Elevation data. Applicants may contribute funds toward a USGS lidar data acquisition activity via the Geospatial Products and Services Contracts (GPSC) 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. Proposals are due by COB on November 8, 2019 and awards will be announced starting December 2019 and continuing through FY2020 subject to available funding.

► 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 was held on August 7, 2019.  






NGP User Engagement Office

The User Engagement Office performs outreach and coordination related to key initiatives of the National Geospatial Program. The office also provides Bureau-level leadership in coordinating geospatial activities in support of emergency response, as well as leadership for the Alaska Mapping Initiative.

USIEI - The United States Interagency Elevation Inventory 

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
