Can a surveyor rely solely on GPS coordinates to re-establish a corner?

A surveyor cannot rely solely on GPS coordinates to re-establish a corner because GPS serves as a measurement tool, but it is not a definitive source of boundary location on its own. It provides data that can be subject to various errors, including atmospheric interference, satellite visibility, and multipath errors. Therefore, while GPS can give a good initial position, it needs to be corroborated with other methods of land surveying, such as traditional ground measurements or the use of existing physical markers or monuments, to ensure accuracy and reliability in the context of legal boundaries.

In the context of land surveying, the reliability of position data is critical, especially in disputes or when establishing legal boundaries. GPS data can show approximate locations, but without cross-verification through physical measurements or referencing established corners, this data might not meet legal standards for boundary establishment. The reliance on GPS alone could lead to inaccuracies that may result in boundary disputes or errors in determining true property lines.
