Why is the Public Land Survey System (PLSS) used?

• A. to describe accurately the location of a parcel of land, and to ease inventory and transfer of land
• B. to map soil types across the country
• C. to monitor climate and weather patterns
• D. to regulate water rights across federal lands

Answer: (A)

Describing exactly where a parcel sits and keeping track of ownership and transfers in a consistent way is what the Public Land Survey System is designed to do. The PLSS creates a grid-based framework (townships, ranges, and sections) so every piece of land can be described unambiguously, which makes it easier to inventory parcels and handle deeds, transfers, and tax records.

This system isn’t about mapping soils, tracking climate, or regulating water rights. Soil maps come from soil surveys, climate patterns come from weather data networks, and water rights are governed by laws and administration rather than land-descriptor methods. So describing land location clearly and supporting reliable record-keeping for ownership and transfers is the best fit for why the PLSS is used.
