Libre Map Project

Libre Map Project

The Libre Map Project is an online collection of all digital USGS 1:24K scale topographic maps (as well as various other GIS data) covering the United States, available for free download.

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 [ [http://www.archive.org/details/maps_usgs Internet Archive: USGS Maps] ] . The map files were then hosted by archive.org to ensure the map data will continue to be freely available to everyone indefinitely [ [http://redjar.org/jared/blog/archives/2006/10/29/libre-map-project-update/ Libre Map Project Update] ] . 56,000 maps in Digital raster graphic form were acquired on DVD's for $1600 to make the data available [ [http://www.cyburbia.org/node/284 Libre Map Project: Free the Maps!] ] . 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 [ [http://libremap.org/ Libre Map Project] ] .
