The Public Land Survey System (PLSS) is a method used in the United States to divide and describe land. Established in the late 18th century, it helps organize land for sale and development. The system divides land into townships, which are further divided into sections, making it easier to identify and manage parcels of land. The PLSS is essential for land ownership records and is used by various government agencies, land surveyors, and property owners. It provides a standardized way to reference land locations, ensuring clarity in land transactions and helping to prevent disputes over property boundaries.
