The National Map is a collection of free, nationally-consistent geographic datasets that describe the landscape of the United States and its territories.
Included in The National Map are the latest elevation data from the 3D Elevation Program (3DEP), surface water data from the 3D Hydrography Program (3DHP) and National Hydrography Datasets (NHD), and place name data from the Geographic Names Information System (GNIS). In addition, The National Map provides continuously-updated, seamless datasets for recreational trails, roads, boundaries, structures, and more. See table below for more information.
The National Map also serves as the data source for modern USGS topographic maps such as US Topos and OnDemand Topos. US Topo maps and scans of historic USGS topographic maps are also available as a part of The National Map.
Data and products from The National Map can be used by government, industry, academia, as well as the public, in support of geologic mapping, natural hazard planning, natural resource conservation, emergency management, recreation, and many other applications.
The National Map is managed by the USGS’ National Geospatial Program in coordination with federal, state, and local partners and may be accessed through data download, web map services, and an online viewer.
