Description: The collection of topoView related services highlight the topographic maps scanned for the USGS’s Historical Topographic Map Collection (HTMC). The goal of this scanning, which started in 2011, is to provide a digital repository of USGS 1:250,000 scale and larger (more detailed) maps printed between 1884 (the inception of the topographic mapping program), and 2006. Currently, there are more than 178,000 maps in the HTMC. For additional information on topoView and the HTMC, go to http://ngmdb.usgs.gov/maps/topoview/.
