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.

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.

The U.S. Geological Survey (USGS) Watershed Boundary Dataset (WBD) is a national hydrologic unit (HU) geospatial dataset that defines surface drainage areas for the United States. This dataset provides a foundation for local, regional, and national applications to manage, archive, exchange, and analyze data by HU.

In this lesson, we will provide an overview and demonstrate how to use The National Map’s web services in a mapping application. Although downloading data from The National Map is a popular option for many users, there are numerous situations where it may be preferable to simply call TNM web services into your mapping application.
