Boundary lines and corners are fundamental aspects of land surveying, and uncertainties can arise from various factors that affect their determination. One of the primary factors contributing to uncertainty is the availability, condition, and integrity of controlling monuments. Controlling monuments are physical markers that define property corners and boundaries. If these monuments are missing, damaged, or improperly placed, it can lead to confusion about where the actual boundary lines lie. Accurate boundaries rely on these reference points being precise and intact, as they serve as the basis for measurement and verification.

In contrast, while weather conditions during the survey can affect visibility and possibly the survey process, they do not intrinsically alter the established boundaries. The surveyor's familiarity with the area can certainly influence the efficiency of the survey but does not directly relate to the accuracy of the boundary lines themselves. Lastly, the tools used for measurements play a role in the precision of the survey results but are not as critical as the actual monuments that define the corners and limits of the properties surveyed. Thus, the condition and reliability of controlling monuments is a key factor in ensuring accurate boundary determination.
