Township maps are often available online at the website of individual townships, such as the detailed maps of the area offered by the Charter Township of Waterford in Michigan. State websites, such as the Pennsylvania Historical and Museum Commission, may also offer collections of township maps.
Other state-based sites that offer online maps of townships include the travel information page from the Wisconsin Department of Transportation. Maps showing township boundaries are available by county.
Individual counties may include township maps on their official website. For example, Tuscola County offers township tax maps of its cities. Historical township maps may also be posted online by local universities.
