This National Map training is an overview of the Work Unit Extent Spatial Metadata (or WESM) for USGS 3D Elevation Program data. The WESM contains information about lidar projects, including lidar quality level, data acquisition dates, and links to project-level metadata. In this video, you’ll learn about WESM attributes, the online data dictionary, and how to query the WESM to find lidar data...

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. Learn more about The National Map. Looking for more? Find all of our videos on the National Map Training page.

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.

This brief National Map training video compares and contrasts two U.S. Geological Survey topographic maps: US Topo and OnDemand Topo maps from the topoBuilder application. Learn more at USGS.gov/TopoMaps.

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 Entwine site.

This video tutorial demonstrates usage of the Dynamic Elevation Service as a Web Coverage Service (WCS). If using ArcGIS Pro 3.7 or AGOL 2026 (or later), the multi resolution visualizations that are demonstrated are not available through the WCS format. Instead, access these processing templates using the 3DEPElevation Image Service format ( https://elevation.nationalmap.gov/arcgis/rest/services...

This National Map training video is a brief introduction to using the topoBuilder application to build customized USGS topographic maps centered anywhere in the United States and territories that use the best available data of The National Map. Learn more at USGS.gov/topoBuilder.

This National Map training video is an introduction to using the LidarExplorer application to easily access lidar data and derived products. In LidarExplorer, you can search for lidar projects, digital elevation models, and lidar point cloud files to meet your needs.

This lesson will show how to use the Domestic Names Search Application to find names of geographic features. By the end of this lesson, you will be introduced to the Geographic Names Information System, understand the search application for U.S. domestic geographic names, and see some search options and help features.
