What does "meridian" refer to in the context of land description?

In the context of land description, "meridian" specifically refers to a vertical line used in land surveys. This terminology is integral to the system of surveying and defining land parcels, particularly in the United States, where land is often described using a rectangular survey system, known as the Public Land Survey System (PLSS).

The meridian serves as a fundamental reference point for mapping and dividing land, providing a north-south line that helps in establishing townships and ranges. This is essential for accurately plotting properties on maps and ensuring that land descriptions are precise and standardized, which is crucial for legal documentation and property transactions.

Understanding this concept is vital for anyone working in real estate, land surveying, or land use planning, as it lays the groundwork for how land is organized and referenced in legal contexts.
