What role does a 'section' play in land measurement?

A 'section' plays a crucial role in land measurement by defining a square mile of land. In the context of the Public Land Survey System (PLSS), which is used primarily in the United States for surveying and mapping, a section is a specific unit that measures one square mile, which is equivalent to 640 acres. This system divides land into townships, and each township contains 36 sections arranged in a grid pattern. Understanding sections is essential for land management, real estate, and property development as they serve as fundamental blocks in the mapping and ownership of land. The use of sections allows for easier referencing, assessing, and navigating land parcels, particularly in rural areas.
