Updated USGS topos collection now available via Topo Explorer
In collaboration with the US Geological Survey (USGS),the Living Atlas team recently updated Esri’s online USGS historical topographic map collection with over 1,745 new maps, bringing the total number of maps in the collection to over 181,000.
These maps are part of the USGS Historical Topographic Map Collection (HTMC) which includes all the historical topographic quadrangle maps (quads) that had been printed since the USGS was established in 1879.
It is easy to explore and download these maps, or quickly create an ArcGIS Online map, using the recently updated Historical Topo Map Explorer app. The app provides a visual interface to search and explore the historical maps by geographic extent, publication year, and map scale.
