The Government Rectangular Survey is a rectangular system of land surveying that divides a district into quadrangles, townships, and sections, predominantly used in most western states of the USA.
A legal description is a detailed way of describing a piece of real estate that is accepted legally and used for property-specific documentation. It identifies the property through various surveying methods such as government rectangular survey, metes and bounds, or recorded plat (lot and block number).
A section of land, as defined in the Government Rectangular Survey, is one square mile. This system divides land into a grid where each township contains 36 sections, each being one square mile or 640 acres in area.
