What is the primary function of correction lines in land description?

The primary function of correction lines in land description is to adjust for Earth's curvature. When land is surveyed, especially in large areas, the curvature of the Earth can impact measurements. Correction lines help ensure that the grid of surveyed land remains accurate over long distances. This function is crucial because without these adjustments, the surveys would lead to land parcels that gradually distort from their true dimensions as one moves farther from the initial reference point. This correction process maintains uniformity and precision in land descriptions, which is essential for legal and practical purposes in land ownership and development.
