Meridian lines in land surveys are used primarily for what?

Meridian lines in land surveys serve the crucial function of defining north-south boundaries. These imaginary lines, which run longitudinally from the North Pole to the South Pole, provide a reference for determining the direction and placement of land parcels in relation to geographic coordinates. By establishing a consistent frame of reference, meridian lines help surveyors accurately identify the orientation and extent of property boundaries.

Understanding the importance of meridian lines is particularly vital in land survey practices, as they play a significant role in creating legal descriptions, mapping, and setting property limits. The alignment of these lines ensures that land boundaries are consistent with the earth's curvature, facilitating precise measurements and legal clarity regarding ownership.
