Fundamentals of Surveying (FS) Practice Exam

In surveying, what does a clear line of sight facilitate?

1. Increased distance measurements

2. Improved data accuracy

3. Faster survey completion

4. Elimination of atmospheric interference

The correct answer is: Improved data accuracy

A clear line of sight is crucial in surveying because it directly influences the accuracy of the measurements taken. When surveyors can see their targets without obstructions, they can ensure that the measurements are based on direct lines, free from distortions caused by obstacles. This unimpeded view allows surveyors to more precisely align instruments, reduce errors in angle measurements, and obtain accurate distance readings, all of which contribute significantly to the overall data accuracy. While factors like distance, survey completion time, and atmospheric conditions also play roles in surveying, they are not as directly impacted by the clarity of the line of sight as accuracy is. Hence, a clear line of sight is paramount for achieving reliable and precise results, which is why the focus is on improved data accuracy.
