History
The Libre Map Project was started by Jared Benedict and around 100 additional individuals contributing money to purchase (or "liberate") a full set of 1:24K scale USGS topographic maps in Digital raster graphic form.[1] The map files were then hosted by archive.org to ensure the map data will continue to be freely available to everyone indefinitely.[2]
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.[4]
