NCEES Principles and Practice of Surveying Practice Exam

Which of the following defines a good monument for land surveying?

1. Visible only during the day

2. Easily disturbed by natural elements

3. Permanent and certain in location

4. Temporary and movable

The correct answer is: Permanent and certain in location

A good monument in land surveying is characterized by being permanent and certain in location. This quality is crucial because monuments serve as reference points that define boundaries and can be used for future surveys. A permanent monument ensures that it will not be easily lost or moved, providing reliable and consistent points for land measurement and demarcation over time. This attribute is essential for maintaining the integrity of property lines and for legal matters involving land ownership. In contrast, a monument that is visible only during the day lacks the reliability needed for surveying, as it may not be usable or identifiable at all times. A monument that is easily disturbed by natural elements can lead to inaccuracies in future surveys, as it may be moved or destroyed, making it an unreliable reference point. Additionally, temporary and movable monuments do not provide the stability and permanence required for effective surveying practices, as changes in their location could lead to disputes over land boundaries and issues with land records.
