What is the name of the current system used for surveying?

The current system used for surveying is known as the Rectangular System, often referred to in the context of the Public Land Survey System (PLSS) in the United States. This method organizes land into a grid of townships and ranges, allowing for precise delineation of property boundaries. The Rectangular System utilizes a network of baselines and meridians to create a structured approach to land division, facilitating consistency and accuracy in surveying and property descriptions.

This system has historical significance as it was established to organize vast tracts of land, especially in the western territories, making it easier to identify and communicate property locations. The use of this standardized grid system is essential in title insurance and real estate transactions, as it provides a clear framework for determining property lines and ownership.

The other options presented do not represent established systems used in surveying. The Quadratic, Circular, and Linear systems do not apply to the standard practices in land surveying or property description, reinforcing that the Rectangular System is indeed the correct and relevant choice in this context.
