Detailed Description

This map of the United States and its territories shows geographic extent of the first-ever nationally consistent hydrography data acquired from high-resolution 3D Elevation Program (3DEP) data. FY24 projects are the result of project submissions accepted through the 3D National Topography Model (3DNTM) Data Collaboration Announcement (DCA) and through ongoing Federal coordination via the 3DHP Working Group and the Alaska Mapping Initiative.

 

Explanation

  • 3DHP Data1
    • Striped Orange = FY24 DCA Project Submission Accepted (subject to change)
    • Periwinkle Blue = FY24 Partnerships In-Progress (subject to change)
    • Dark Blue = Available or In-Progress
    • Medium Blue = Data Contribution Pending

13DHP may be acquired from lower resolution DEM where 3DEP data is restricted

  • 3DHP Data:
    • Hydrography derived from 1m Digital Elevation Model (DEM) created from 3DEP QL2 or better lidar (5m DEM from IfSAR in AK)2 

2Hydrography acquired to meet Elevation-Derived Hydrography specification and READ rules v1.0 or later. TM-11B11 and 11B12

  • Sources: 
    • Hydrologic Units as defined by the Watershed Boundary Dataset (WBD)
