  2. Map of Harrisburg searchable by last name. Best if you want to search for a specific person or ancestor who lived in the city in 1900. In addition to its search feature, the user has the option of browsing by households and changing basemaps.
  3. Swipe Map of Harrisburg and the Old Eighth Ward. Shows the 1901 map underneath modern aerial images of the city. This map shows the boundary and significant places of the Old Eighth Ward. Best for comparing Harrisburg today with Harrisburg in 1901. Also includes a search feature (by place) and a geolocator for mobile users.

The maps and the data they contain were developed as a collaboration between faculty and students at Messiah College and Harrisburg University of Science and Technology. The  Historical Society of Dauphin County generously provided JPEG scans of the entire 1901 Harrisburg Title Company Atlas (the layer visible as the historical map of the city). Messiah College students created a complete database of the population in 1900, while GIS students from Messiah and Harrisburg University created building polygons and individual census record points in GIS mapped to the level of individual properties.
