Maps are an extremely valuable resource for understanding agricultural information. The maps found here range from simple aerial and historic maps, to more complex compilations of data on the state level.  Maps can provide information on numbers as well as ages of historic farms and farmsteads in an area, and can also be used to take a look at larger trends across and between counties and the rest of the commonwealth.

1927 Census Maps
These maps were created using the 1927 Triennial Pennsylvania Agricultural Census' county summaries. Most of the maps were created in ArcMap.  This is not free software, however if you do have access to it, or wish to purchase it, we can provide you with the data set on the county and municipality levels.

Historic Maps
Historic maps can be helpful in documenting an historic farm or farmstead. A company called Maptech has created a website which contains historic USGS topographic maps that can be found by town name, as well as quadrant. It can be found at http://historical.maptech.com.

The Pennsylvania State Archives also keeps historic survey records and warrant registers. These records can be extremely helpful, and can be found at the Land Records page of the State Archives.

Aerial Maps
Feel free to browse historic aerials through the Penn Pilot Project, which is provided by Pennsylvania State University, DCNR, and the Pennsylvania Historical and Museum Commission.  The photos date from 1937-1970, and are available for download as needed.
