Now Available: USGS releases the 3D National Topography Model Call for Action - Part 1: The 3D Hydrography Program | U.S. Geological Survey

When fully implemented, the 3D Hydrography Program will provide benefits to the Nation estimated at more than $1 billion dollars annually.

The 3D National Topography Model Call for Action—Part 1. The 3D Hydrography Program

The U.S. Geological Survey is initiating the 3D Hydrography Program (3DHP), the first systematic remapping of the Nation’s surface waters since the original 1:24,000-scale topographic mapping program was active from 1947 to 1992. Building on decades of experience maintaining the National Hydrography Dataset (NHD), the Watershed Boundary Dataset (WBD), and the NHDPlus High Resolution (NHDPlus HR), the 3DHP will completely refresh the Nation’s hydrography data and improve discovery and sharing of water-related data. The design of the 3DHP is based on the results of a study that estimated that the fully implemented program would have the potential to provide more than $1 billion in benefits to Federal, State, Tribal, Territorial, and local governments and to private and nonprofit organizations every year, in addition to myriad societal benefits. The 3DHP would directly support better decision making regarding water resources by providing more accurate, complete, and integrated information than is currently available.The...

Toward a searchable, network-linked database of river inundation extents 

This post provides a brief description of work done through fiscal year 2022 for the River Corridors project as part of the National Hydrologic Geospatial Fabric (NHGF) project to create a new database.
