A guide to the ASU Library Map and Geospatial Hub.

Map and Geospatial Hub Topographic Holdings


As a federal depository library, the Map and Geospatial Hub maintains a collection of topographic maps produced by U.S Geological Survey (USGS).  Topographic map scales include 1:24,000, 1:52,500, 1:100,000, 1:250,000 and other scales for historic maps. 

Since USGS no longer distributes print topographic maps, see National Geologic Map Database and the USGS Store link below for information on downloading maps.
