National Map Viewers

The National Map is constantly evolving to incorporate newer and better data and services. New viewing capabilities and data download services for The National Map are planned for release in late spring or summer of 2009. Check this page for the latest developments.

Until the new capabilities are implemented, The National Map includes two primary data viewers: the first viewer, The National Map Viewer, has the primary role of viewing distributed data sets from many contributing Federal State and Local Partners through dynamic web map services. The second viewer, The National Map Seamless Server, is the primary site for downloading USGS imagery, elevation and land cover data.

Interactively View National Map Data:

The National Map Viewer The National Map Viewer is the face of The National Map and allows the user to interactively view The National Map data as a map, customize the view, and print maps. It provides public access to high-quality geospatial data and information from the eight National Data sets. Map tools allow the user to move around the map, zoom in and out, identify features, and perform other functions. The Viewer currently is undergoing major revisions at: http://nmviewogc.cr.usgs.gov/.

The National Map Seamless Server The National Map Seamless Server enables a user to view and download many geospatial data layers, such as the National Elevation Dataset, the National Land Cover Dataset, high resolution orthoimagery, and other seamless data for the Nation. The Seamless Server can be found at: http://seamless.usgs.gov/.
