Texas Surveyors Practice Exam

When do direction and distance control over found monuments?

1. When monuments are clear and identifiable

2. In cases with no monuments present

3. Always, regardless of other factors

4. When true north is identified

The correct answer is: In cases with no monuments present

The understanding of when direction and distance control over found monuments revolves around specific surveying principles. In cases where there are no monuments present, surveyors rely heavily on established directions and distances to establish boundaries and points. This situation often arises when starting a new survey or in cases where monuments may have become lost or obliterated. When monuments are not available, surveyors must utilize their measurements and calculations of distance and direction to accurately determine the positions as described in legal descriptions or previous survey records. Consequently, this reliance on directional and distance data becomes crucial in ensuring the accuracy and integrity of the surveying work. While clear and identifiable monuments are important in delineating property lines and ensuring proper alignment, they do not take precedence over the defined distances and directions in the absence of these monuments. The importance of establishing true north is also essential for orientation, but it is not the primary factor when considering the lack of monuments.
