This video summarizes the 3DEP and 3DHP programs for a Tribal audience, providing an overview of the program and its goals and methods. The presentation includes information about topics of possible concern to Tribes, and points of contact to address questions and concerns.

The call will cover USGS Hydrography Program information: 

Our presenter will be Josh Greenberg, the Washington Hydrography Data Steward (WASHD). 

This National Map training video provides an overview of The National Map Viewer, an interactive web map for viewing and exploring the GIS data available through The National Map, and has been updated to include 3D functionality.

The topic will be “3DHP Overview and Status – FY25 Accomplishments and FY26 Plans”

Presenter is Steve Aichele, National Geospatial Program Hydrography Planning and Management Lead

This National Map training video demonstrates how to access the 3D Hydrography Program (3DHP) feature service, add it to an ArcGIS Pro project, modify symbology and visualization, as well as select and export data. 

The informational webinar for the Federal fiscal year (FY) 2026 3D National Topography Model (3DNTM) Data Collaboration Announcement was held on Wednesday, August 6, 2025 at 1pm ET. The USGS provided an overview of the application process followed by a Q&A session.

Steve Aichele, the National Geospatial Program Hydrography Management and Planning Lead, announced publication of the Holston River, TN hydrologic unit 10 (0601010403) in the 3D Hydrography Program web map services and provided update on HydroAdd planned release of the Beta version (August 2025) and version 1.0 (September 2025).  

Steve Aichele, the National Geospatial Program Hydrography Management and Planning Lead, announced release of the Elevation Derived Hydrography Specification 2024 Revision A3 and updates on the following:

This National Map training video will demonstrate how to use QGIS, a free and open-source GIS software, to import and visualize lidar point cloud data from the USGS 3D Elevation Program (3DEP). 

This National Map training video will demonstrate how to create and implement a Point Data Abstraction Library or PDAL pipeline script that will generate derivative elevation rasters from USGS 3D Elevation Program (3DEP) lidar point cloud source data from the USGS E

Steve Aichele, the National Geospatial Program Hydrography Management and Planning Lead, announced release of updated Elevation Derived Hydrography Specifications and publication of the following products and services: 

This National Map training video demonstrates how to use the 3D Elevation Program’s Dynamic Elevation Service in ArcGIS Pro and ArcGIS Online (AGOL). By the end of this lesson, you will be able to add the Dynamic Elevation Web service to ArcGIS Pro, enable raster processing templates, and retrieve a spot elevation.

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. 

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.
