3D Hydrography Program FY24 Partnerships in Alaska
This map of Alaska 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 ongoing Federal coordination via the 3DHP Working Group and the Alaska Mapping Initiative.

December 2024 USGS Hydrography Community Call: Delivering and Using 3D Hydrography Program (3DHP) Data
linkThe 3D Hydrography Program (3DHP) database will initially be populated with the National Hydrography Dataset (NHD) features, mapped to the new data model. The NHD-source features will be replaced with hydrography derived from the 3D Elevation Program (3DEP) lidar and IfSAR data as it becomes available.

The 3D Hydrography Program at one year – what was accomplished in FY24, what is planned for FY25?
linkFederal Fiscal Year 2024 was the first full operational year for the 3D Hydrography Program. We made significant progress in a number of areas, publishing final versions of legacy products, and developing processes for the new program. This presentation will provide an overview of what was accomplished in FY24 and what is planned for FY25.

USGS-NFHP Webinar - The National Map and the 3D Hydrography Program
The USGS-NFHP Webinar on the 3D Hydrography Program (3DHP) and The National Map (TNM) provided a deep dive into the current state and future direction of USGS hydrography and elevation data, focusing on the replacement of legacy datasets with highly accurate, 3D-enabled data.

A Statewide Hydraulic Modeling Tool for Stream Crossing Projects in Massachusetts
The U.S. Geological Survey and the University of Massachusetts at Amherst (UMass Amherst), in cooperation with the Massachusetts Department of Environmental Protection (MassDEP), began a series of studies in 2019 to develop a web-based statewide hydraulic modeling tool to provide preliminary culvert designs for stream-crossing projects in Massachusetts.
