This via the USGS as The National Geospatial Program has launched the USGS Historical Topographic Map Collection. Dy today’s launch, the USGS will offer more than 90,000 of the 200,000+ USGS historical topo maps – some dating back to the Agency’s founding! (126+ years ago). The maps are georeferenced and can be downloaded for free from the USGS Store. Since they are in a GeoPDF format, no special programs are required, and they can be used in conjunction with the US Topo maps.
Some details… Nearly 90,000 high resolution scans of the more than 200,000 historical USGS topographic maps, some dating as far back as 1884, are now available online. The Historical Topographic Map Collection includes published U.S. maps of all scales and editions, and are offered as a georeferenced digital download or as a scanned print from the USGS Store.
