one sees that our farmland and towns have a square pattern. Township & Range: Flying over the western U.S. From the air it can be seen that land parcels are irregular in size and shape. This one is native to England and can be found in the original thirteen colonies. Metes and Bounds: This system uses physical features of local geography along with directions and distances to define and describe boundaries of land parcels. Most farmland was along rivers and the system created long rectangular plots of farmland to give equal access to the river. Long Lot System: This one was put in by the French and used in French regions of North America such as Canada and Louisiana. The ones you need to know for APHG are on this page. The shapes evident in farmland and villages often have their roots in cadastral systems.
Patterns of land use in rural areas can be seen from the air if you are flying in an airplane.
On the other hand, you may want to account for all potentialities.Cadastral systems are land use and distrubtion systems. Perhaps your area of interest will not include any of the anomalies I've mentioned. To see this complexity first-hand, Washington state townships/section data can be downloaded here, and here's the metadata. Additionally, there are other types of subdivisions in addition to sections (including donation land claims, federal tracts, and protracted blocks).
However, townships and their subdivisions may deviate - both in number and in shape - for a variety of reasons, from the difficulties encountered while surveying through rugged terrain to fraudulent 1800's era survey reports compiled not in the field, but at the local watering hole (or so I've been told - I'm not a surveyor).įor example, in Washington State, half-townships were added to "fill in the gaps" between different initial survey projects that did not properly meet up. To add what Rudy Stricklan states, the nominal township is a square, six miles on a side, containing 36 evenly-divided sections.
