(11 Oct 2019) In collaboration with the US Geological Survey (USGS), Esri recently updated the online USGS historical topographic map collection with over 1,700 new maps.
Esri’s USGS topographic map collection now contains 177,061 historical quadrangle maps dating from 1882 to 2006. Previously available only as printed lithographic copies, high-resolution images of these maps are freely available online and can be downloaded as georeferenced TIFFs for use in web maps, geographic information systems (GIS), and other applications. In this update, 1,227 new maps were added to the collection and 530 maps were replaced with better-quality images.
