U.S. Geological Survey Opened up its Historical Archive
The USGS announced yesterday that it was in the process of releasing all of its maps to the public. This organization has been mapping the USA since 1879, and its archive dates back to 1884. All the maps made between 1884 and 2006 are going to be put online for the public to see.
The topographic map collection covers all states and U.S. territories that have been mapped by the USGS. That’s over 200 thousand maps, all of which have been scanned and converted to GeoPDF format.
