The 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.

Federal 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.
