Louisiana Topos Now Available

Over the last few years, the United States Geological Survey (USGS) has been working to scan and process its enormous printed map collection -- of U.S. states, Puerto Rico, the Virgin Islands, and U.S. trust territories -- to make them available as free downloads in electronic format (GeoPDF).

Over the last month, the topographical maps of Louisiana became available... with New Orleans topographic coverage dating from 1891-2009.
