CST Level 1 Land Surveyor Certification Practice

Which of the following is an example of a personal source of error in surveying?

1. Wind interference

2. Kinks in the tape

3. Poor reading of the tape

4. Temperature fluctuations

The correct answer is: Poor reading of the tape

The correct answer highlights a personal source of error, which stems from the subjective interpretation and actions of the surveyor. In this case, a poor reading of the tape often arises from factors such as inexperience, fatigue, or distractions, all of which can lead to inaccuracies when measuring distances. Unlike systematic errors caused by environmental factors, personal errors can vary widely depending on the individual performing the measurement. Each of the other options represents different types of errors that do not originate from the surveyor's direct interpretation or immediate actions. Wind interference typically impacts equipment stability, kinks in the tape affect the physical condition of the measuring tool rather than the surveyor’s actions, and temperature fluctuations can cause expansion or contraction of measuring equipment but are not directly related to the surveyor's personal decision-making or interpretation. Thus, recognizing a poor reading of the tape as a personal source of error emphasizes the role of the operator's experience and attentiveness in achieving accurate survey results.
