In real estate and land surveying, meridians are imaginary north south lines used as reference points in the measurement and description of land. They intersect with base lines to establish a framework for identifying and locating parcels of real property.
Meridians are a fundamental component of the rectangular survey system, also known as the government survey system. By providing consistent reference lines, meridians allow surveyors to accurately divide land into townships, ranges, and sections for legal description and recordkeeping purposes.
