What is the rectangular survey system used for?

The rectangular survey system, also known as the Public Land Survey System (PLSS), is primarily utilized to survey and describe land using a grid-like structure based on specified meridians and baselines. This system divides land into ranges and townships, providing a systematic methodology for identifying and documenting parcels of land across large areas, particularly in the United States.

Using meridians as north-south lines and baselines as east-west lines, this approach allows for a clear and organized framework for land distribution and property description. It is particularly useful in regions that did not have pre-existing established boundaries, making it easier for the government to sell and manage land. The importance of the rectangular survey system lies in its ability to create a standardized method for land measurement and ownership identification, which is crucial in real estate transactions, land management, and property development.
