What is the Public Land Survey System also referred to as?

• A. Rectangular Survey System
• B. Sector Reference System
• C. Cartesian coordinate system
• D. Coordinate system

Answer: (A)

The main idea is the name of the land description framework used in US surveying. The Public Land Survey System is also referred to as the Rectangular Survey System because it organizes land into a grid of right-angle, rectangular blocks. This system relies on principal meridians and baselines to create townships and sections, producing a consistent, grid-based description of parcels over large areas. It differs from general coordinate ideas like the Cartesian coordinate system, which uses fixed x and y axes independent of a surveyed land grid; in PLSS the coordinates are anchored to survey lines and directions rather than universal axes. The term Rectangular Survey System specifically captures the grid-based method used for describing land parcels, which is why it’s the correct name.
