December 2024 USGS Hydrography Community Call: Delivering and Using 3D Hydrography Program (3DHP) Data

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. Diverse applications for the input features that the 3DHP model supports will be discussed in detail, including additional functionality and derivatives available for the elevation-derived hydrography and user-specific targeted views such as interfaces for cartographic, full linear and catchment realization, and linear referencing. 3DHP data delivery, accessibility, and sharing based on the principles of the Internet of Water (IoW) will also be highlighted.
