Which of the following describes a meridian in land surveying?

A meridian in land surveying is defined as an imaginary line that runs north and south. Meridians are crucial for establishing a grid on maps and are used in conjunction with parallels, which run east and west. Together, these lines help to create a system of coordinates that can accurately represent locations on the Earth's surface. In the context of land surveying, meridians are often used as reference points for determining property boundaries and for navigation purposes.

Understanding meridians is fundamental in fields such as cartography, geography, and real estate, as they form part of the coordinate system that aids in clearly delineating land plots. The role of meridians contributes significantly to creating a structured approach to land description, including the use of the Public Land Survey System in the United States.
