The National Map

Applications and Maps | Topographic Data | Learn More

The National Map is a suite of products, services, and applications that provide access to base geospatial information representing the topography, natural landscape, and built environment of the United States and its territories.

The National Map supports digital and print versions of topographic maps, data download, web map services, and online viewing of maps and data. Government, industry, academia, as well as the general public, can use the geospatial data and maps to enhance their recreational experience, make life-saving decisions, support scientific missions, and for countless other activities.

The National Geospatial Program and its partners acquire and integrate authoritative geospatial data from a variety of sources and makes the resulting nationally consistent geospatial data layers available to all through The National Map. The National Map also serves as the data source for cartographic products, such as US Topo and OnDemand Topo maps, and provides access to digital historical topographic maps.

National Map product and service implementation is supported by USGS' National Geospatial Technical Operations Center and Earth Resources Observation and Science (EROS) Center, which comprise the National Geospatial Directorate.
