We currently offer three interactive maps of the city of Harrisburg in 1900-1901 but will be expanding the features and underlying datasets of these maps in spring 2020 (Note: for ready-made static maps of the city and its population at different points in time, visit the datasets page).
The following three interactive maps allow the visitor to explore Harrisburg in different ways
- Map of Harrisburg searchable by address. Best if you want to search for a specific place in the city. In addition to its search feature, the user has the options of browsing by household, changing layers and base maps, changing opacity of layers, and measuring distances.
- 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 base maps.
- 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, and GIS students from Messiah and Harrisburg University created building polygons and individual census record points in GIS mapped to the level of individual properties.
