Greater Philadelphia GeoHistory Network

The Greater Philadelphia GeoHistory Network contains geographic materials connected to the history of Pennsylvania, New Jersey, and the City of Philadelphia. The available resources include aerial photographs, city directories, atlases, surveys, property maps, topographical maps, and transportation maps. An interactive map viewer enables users to view layers of historic maps at various transparencies in conjunction with a current streets overlay.

The historic maps in the map viewer are available as tile services for appropriate projects - contact the project for further information.
