You've seen it on the web but it's now an official publication. News from USGS...
We have some exciting 3D National Topography Model (3DNTM) news to share.
The National Geospatial Program is pleased to announce that the 3D National Topography Model Call for Action – Part 1: The 3D Hydrography Program has been released.
The Call for Action outlines an ambitious nine-year vision to completely replace the Nation's surface water mapping, much of which is decades old and based on ground surveys, with highly accurate hydrography derived from 3DEP elevation data. The 3D Hydrography Program (3DHP) is the first consistent, systematic remapping of the Nation's hydrography since the original 1:24,000-scale mapping program was active from 1947 to 1992.
