Historic Maps Go Digital, More than 161,000 Historic Topographic Maps Now Available from USGS (Free)
The U.S. Geological Survey (USGS) has publicly released more than 161,000 digitally scanned historical maps spanning in excess of 130 years and covering the conterminous lower 48 states. This Historical Topographic Map Collection provides a comprehensive repository of the landscape of our Nation and tracks changes through time, providing essential clues critical in the understanding our Nation’s topography, geography and development.
With the recent completion of the states of Massachusetts and Florida, the Historical Topographic Map Collection can now offer, for free download, digital versions of the USGS legacy topographic map series which includes all scales and all editions originally published for the entire continental U.S.
As chartered, the USGS topographic mapping program has accurately portrayed the complex geography of our nation through maps in the lithographic printed format. Since the official release of the digital, scanned collection this past September, more than 1.2 million historical topographic maps have been downloaded from the website– an average of more than 5,700 maps per day.
