The National Map (TNM) is the collection of mapping products and services produced by the USGS National Geospatial Program. Understanding the complexity and richness of TNM is now made easier for geospatial data users, scientists, and the public, with this series of video lessons that show how to use TNM services, applications, interfaces, data, and tools. Topics include but are not limited to: using 3D Elevation Program (3DEP) data, the National Hydrography Dataset (NHD), TNM viewers and applications, topographic maps, 3DEP collaboration tools, and EarthExplorer.
