56,000 maps in digital raster graphic form were acquired on DVDs for $1600 to make the data available. [3] Additional data made available through the project includes SVG boundary files for every US state, Topologically Integrated Geographic Encoding and Referencing (Tiger)/Line 2003 vector map data, and the USGS GeoNames database.

Georeferenced map images are available from the USGS as digital raster graphics (DRGs) in addition to digital data sets based on USGS maps, notably digital line graphs (DLGs) and digital elevation models (DEMs). In 2015, the USGS unveiled the topoView website, a new way to view their entire digitized collection of over 178,000 maps from 1884 to ...
The National Map is part of the USGS National Geospatial Program. [3] The geographic information available includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures and land cover. The National Map is accessible via the Web, as products and services, and as downloadable data ...
