According to standard surveying practices, how often are standard parallels generally marked?

Standard parallels are lines of latitude used in land surveying to create a grid system for mapping and subdividing land. In the context of surveying, they are typically established at regular intervals to assist in the sectioning of large tracts of land, particularly in the Public Land Survey System (PLSS) utilized in the United States, including Oklahoma.

Every 24 miles is the established convention for marking standard parallels. This interval allows for adequate spacing between these parallels, which is crucial for the effective partitioning of land into sections. These sections are 1 mile by 1 mile squares, and establishing parallels at this distance helps maintain a consistent and systematic approach to land division.

Understanding the significance of standard parallels and their proper intervals is essential for professionals involved in land surveying, as it impacts not only the organization of land but also the legal descriptions of property boundaries. The choice of 24 miles ensures clarity and precision in maps and documents, which is foundational in the field of land surveying.
