Topic: The Next Generation of Hydrography
Date: August 24, 2021

Presenters: Becci Anderson and Al Rea

The USGS is developing the 3D Hydrography Program (3DHP) as the surface water mapping component of the new 3D National Topography Model (3DNTM.) The 3DNTM is the next generation of the 3D Elevation Program (3DEP) and National Hydrography Datasets, and includes high-resolution elevation, inland bathymetry, hydrography derived from elevation, and connections to groundwater and engineered hydrologic systems. The 3DHP will provide critical data related to flood forecasting and response, agricultural planning, infrastructure design, fisheries and stream ecology research and management, water quality studies, and other emerging applications.

This presentation will provide an overview of 3DHP plans including scope and timelines for the emerging program.
