The National Map Viewer and Download Platform allows visualization and
download of our most current topographic base map data and products for free. Managed by the USGS National Geospatial Program (NGP), users can access data from all eight primary data themes of
The National Map, and products, such as US Topo, Historical Topographic Maps, and Map Indices. The viewer platform was initially extended upon the National Geospatial Intelligence Agency's (NGA) Palanterra x3 viewer.
Beta applications are in development to replace functionality of older viewer technology and include:
Bulk Download Client,
Download Manager,
topoView,
Bulk Point Query, and
Mobile Download Client. Additional applications may be added in the future.
Available downloadable data themes are: Elevation, Orthoimagery, Land Cover, Hydrography, Geographic Names, Boundaries, Transportation, Structures, while maps include: US Topo and Historical Topo. The National Map viewer also allows visualization and identification queries (but not downloads) of Other Featured Data, such as Scanned Topo Maps, Ecosystems, Protected Areas, Gap Analysis Program Land Cover, Wetlands, Public Land Survey System, and National Park Service Boundaries. In addition, a Natural Hazards panel is included to view hazards-related information, such as for earthquakes, floods, wildfires, and weather, along with the U.S. National Grid for emergency response.
To research and download historical USGS data, such as Digital Orthophoto Quadrangles or older high resolution orthoimagery and Digital Line Graphs, go to Earth Explorer.
