About TopoView
The USGS National Map program, working with the National Geologic Map Database(NGMDB) project, has launched a new version of the beta application, topoView, for exploring, viewing, and downloading the more than 178,000 USGS digitized legacy topographic maps from the USGS Historical Topographic Map Collection (HTMC). These scanned quadrangle maps, georeferenced at various scales, dating from the late 1880’s to 2010. For more information on the effort to capture the complete map collection, see theHistorical Topo Map Collection web site.
