3DEP By The Numbers

Tracking progress towards the 3D Elevation Program (3DEP) goal to complete the first-ever baseline of consistent high-resolution elevation data - both bare earth and 3D point clouds.

The 3D Elevation Program Initiative - A Call for Action, documented the process to analyze the NEEA requirements and benefits, the comparison of program scenarios (varying quality level and replacement cycle across the nation by cells measuring one degree latitude by one degree longitude), and the recommendation to acquire Quality Level 2 data nationwide (Quality Level 5 in Alaska).

 

A nearly 5:1 return on investment

The 3D Elevation Program Initiative - A Call for Action, states...

The strategy is to leverage funding from partners and to increase contributions from all sources so that the investment rises from the current level of approximately \$50 million to \$146 million annually… At the full funding level, 3DEP could return more than \$690 million annually in new benefits directly to the private sector and indirectly to citizens through improved government program services. When 3DEP data are widely available, further private sector and government innovations will follow for years to come.” (2014, p1).

This would result in a nearly 5:1 return on investment, informing critical decisions that are made across our Nation every day that depend on elevation data, ranging from immediate safety of life, property, and environment to long term planning for infrastructure projects.

 

3DEP is based on community-wide partner investments

The U.S. Geological Survey (USGS) was designated by the Office of Management and Budget (in 2002 through OMB Circular A–16) as the lead Federal agency for terrestrial elevation data. The 3DEP initiative is designed to fulfill that leadership responsibility and to ensure that the needs of the Nation for high-quality 3D elevation data are being met. This role cannot be filled by the USGS alone, and 3DEP is a collaborative effort that includes many partners—Federal agencies and State, Tribal, and local governments—who will work together to build on existing programs to complete the national collection of 3D elevation data. Private sector firms, under contract to the Government, are collecting the data and providing essential technology solutions to manage and deliver these data and services. 

Progress towards the goal to complete a nationwide baseline is due in large part to community-wide partner investments: from fiscal year (FY) FY15 - FY21, USGS funded 31% of 3DEP costs for data acquisition and data processing and management, while the community-wide partners funded 65 for data acquisition, with the remaining 4% of funding coming from disaster supplemental appropriations.  The information below summarizes community-wide partner 3DEP expenditures from FY15 – FY21.

Note: The USGS received \$18.3 million in FY18 and \$10.2 million in FY19 of supplemental funds for lidar acquisition for areas impacted by hurricanes and wildfire disasters. The chart shows the funding by year obligated. For example, the FY19 supplemental funding was received at the end of the fiscal year, and \$2.8 million was obligated in FY19 with the remainder obligated in FY20 and FY21.

The USGS funding for 3DEP is part of the Core Science Systems - National Geospatial Program line item funded by the FY21 enacted budget at $79.454 million. The National Geospatial Program line-item funds 3DEP, the National Hydrography Datasets, US Topo, The National Map viewer, and other components. The FY21 enacted budget included $35.7 million for acquiring, processing, and delivering 3DEP-quality data to meet the community-wide goal.
