Mastery: Surveyor Practice Test 2026 | Exam Prep

When performing a closed traverse with a total station, which of the following is the MOST critical factor to minimize angular misclosure and ensure positional accuracy?

In the context of establishing a high-accuracy geodetic control network, what is the primary advantage of using differential GPS (DGPS) over conventional terrestrial surveying methods for long baselines?

A surveyor is tasked with setting out a complex circular curve with a radius of 500 meters and a tangent length of 200 meters. The total station has a precision of ±3mm over 100 meters. What is the MOST significant source of error the surveyor must meticulously control during the setting-out process to achieve the required positional accuracy for the curve?
