What is a Closing Corner in surveying terms?

1. A previously fixed boundary marked by a corner

2. A corner established by a survey line intersection

3. A reference corner for future surverying

4. A boundary defined by local laws

The correct answer is: A corner established by a survey line intersection

A Closing Corner in surveying refers specifically to a corner that is established by the intersection of survey lines. This concept is essential in the context of land surveying because it plays a critical role in defining property boundaries and closing the loop of a survey. When a surveyor completes a traverse, they must ensure that the final measurements align with the initial points to delineate the property accurately. Closing corners are points that confirm the accuracy of the surveyed lines and ensure that the area is properly defined without gaps or overlaps which could lead to disputes. This is especially important in a legal context where boundaries need to be clear and accurate to prevent future conflicts over land ownership. In contrast, other options describe different types of survey-related points or principles that do not capture the specific definition of a Closing Corner. For instance, previously fixed boundaries, reference corners for future surveying, and boundaries defined by local laws all relate to surveying but don't encapsulate the operational requirement of an intersection point that solidifies the correctness of a closed traverse. Thus, the definition that aligns with the terminology and function of a Closing Corner is centered around its establishment from the intersection of survey lines, confirming the completion of a surveying task.
