In collaboration with the US Geological Survey (USGS), we recently updated Esri’s online USGS historical topographic map collection with over 1,745 new maps, bringing the total number of maps in our collection to over 181,000 (181,008 to be exact). We also corrected a number of maps that our users reported as having georeferencing or other errors.
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. More about this below.
Esri’s USGS historical topographic map collection contains historical quads (excluding orthophoto quads) dating from 1879 to 2006 with scales ranging from 1:10,000 to 1:250,000. The scanned maps can be used in ArcGIS Pro, ArcGIS Online, and ArcGIS Enterprise. They can also be downloaded as georeferenced TIFs for use in these and other applications.
