What do meridian lines represent in government surveys?

Meridian lines represent imaginary north-south lines in government surveys. These lines are part of the rectangular survey system known as the Public Land Survey System (PLSS) that was established to systematically divide land for sale and settlement. Each meridian serves as a reference line from which townships or sections are measured, facilitating accurate mapping and defining property boundaries.

By using meridians, surveyors can create a grid that helps in identifying specific parcels of land based on their relationship to these lines. This is crucial for establishing the legal description of properties as it lays the foundational gridwork from which all other measurements are derived. The connection to the north-south orientation further emphasizes their role in navigation and land mapping, making them essential tools in the real estate sector. Understanding meridians and their function clarifies how land in the United States is organized and can assist in various real estate transactions and assessments.
