3DNTM DCA Projects Web Map

Jonesi, A.B., Thatcher, C.A., Thunen, D.R., Buto, S.G., Jason, A.L., Funk, M.R., 2024, 3D National Topography Model BAA/DCA Projects: U.S. Geological Survey Web Mapping Application, https://geonarrative.usgs.gov/3dntmdcawebmap 

This web mapping application depicts the 3D National Topography Model (3DNTM) Data Collaboration Announcement (DCA) acquisition projects from fiscal year (FY) 2024 to present as well as the 3D Elevation Program (3DEP) Broad Agency Announcement (BAA) projects from FY15-23. The DCA replaced the BAA in FY24 and includes data acquisition partnerships for both the 3DEP and the 3D Hydrography Program (3DHP). The USGS collaborates with many stakeholders including Federal agencies and State, Tribal, and local governments to share costs of topographic and hydrographic data acquisition in support of collective mission and business requirements. The DCA provides a mechanism for partnering with the USGS and other Federal agencies to acquire high-quality 3D elevation and hydrography data to provide the Nation with high-resolution topographic and hydrographic products to support a broad array of applications.    

3DEP projects are depicted in dark green symbology and 3DHP projects are depicted in blue hatched symbology. Watershed Boundary Dataset (WBD) Hydrologic Unit (HU) 2 are in a black outline. There is a middle swipe bar that can be adjusted to view both types of projects individually. Toggling off the swipe feature in the bottom right corner of the page will show both project types at the same time. Layers can be toggled on or off using the layer option in the upper right and clicking the appropriate check box.
