S+SNZ Spatial Measurement Practice Questions - S+SNZ Professional Examination - Spatial Measurement Option (New Zealand) Exam - S+SNZ Spatial Measurement Practice Questions - S+SNZ Professional Examination - Spatial Measurement Option (New Zealand) Exam

Question 1

A surveyor uses a retroreflective prism with a physical offset (prism constant) of -30 mm. If the total station is accidentally set to a prism constant of 0 mm, what will be the effect on the recorded distance?

The measured distance will be 30 mm too short. The measured distance will be 30 mm too long. The measured distance will be correct, as the instrument self-calibrates. The measured distance will have an error that scales proportionally with the distance.

Correct Answer:

The measured distance will be 30 mm too long.

Question 2

When conducting high-precision digital leveling over a distance of 2 km, which of the following field procedures is most effective in eliminating the combined effect of Earth's curvature and atmospheric refraction?

Keeping backsight and foresight distances equal. Using a high-quality invar leveling rod. Taking measurements only at midday when the air is stable. Performing a two-peg test before starting the run.

Correct Answer:

Keeping backsight and foresight distances equal.

Question 3

A total station is set up, and a distance of 1,200 m is measured at a temperature of 35°C and an atmospheric pressure of 1,005 hPa. If the instrument's internal atmospheric correction was left at standard conditions (15°C and 1013 hPa), what is the approximate error introduced into the measurement?

The measured distance will be approximately 24 mm too short. The measured distance will be approximately 24 mm too long. The measured distance will be approximately 5 mm too short. The measured distance will be approximately 5 mm too long.

Correct Answer:

The measured distance will be approximately 24 mm too short.

Question 4

Under the Cadastral Survey Rules 2021, what is the measurement purpose of referencing specified boundary points to permanent reference marks (PRMs)?

To provide physical evidence of the boundary line's position for landowners. To preserve independently measured relationships from which the boundary point can be reliably reinstated if its boundary mark is lost. To serve as the primary coordinate control station for the Landonline database. To satisfy local authority requirements for road alignment setbacks.

Correct Answer:

To preserve independently measured relationships from which the boundary point can be reliably reinstated if its boundary mark is lost.

Question 5

Which of the following GNSS errors is local to the receiver station and cannot be mitigated or canceled out by differential positioning (RTK) techniques?

Ionospheric delay Tropospheric delay Satellite clock error Multipath interference

Correct Answer:

Multipath interference
