What are the intersecting lines that run north and south in the rectangular survey system known as?

In the rectangular survey system, the intersecting lines that run north and south are referred to as principal meridians. These lines serve as a reference point for the land surveying system and are fundamental in defining the boundaries of townships and ranges. Each principal meridian has corresponding base parallels, which run east and west. This geographic framework ensures that land can be accurately measured and described in a systematic manner across various regions.

Understanding the role of principal meridians is essential, as they establish the starting point for other divisions in the rectangular survey system, allowing for precise identification of parcels of land. This is crucial in real estate transactions and property descriptions, as it provides a structured way to locate and delineate real property boundaries.
