About the Collection
The Donald W. Hamer Center for Maps and Geospatial Information digital map drawer contains the subset of our physical map collection that has been digitized and is not protected by licensing or copyright. The digital map drawer contains a nearly complete collection of the Sanborn Fire Insurance Maps of Pennsylvania (1884 – 1938), historical maps from around the world, and an assortment of other historical Pennsylvania maps including the 1861 Tilden Map of Centre County. The digital map drawer can be accessed by using a keyword search on this page; or by keyword and geographic search using the Big Ten Academic Alliance’s Geoportal, to which Penn State contributes.
Some of our digital historic aerial photography imagery collections of Pennsylvania can be accessed using the Pennsylvania Spatial Data Access (PASDA) Imagery Navigator. To access the remainder of our digital aerial photography collections, please contact us directly: UL-MAPS@LISTS.PSU.EDU
