RPLS Surveying Principles and Methods 3

Question 1

What is the primary advantage of GPS RTK (Real-Time Kinematic) surveying over post-processed static GPS?

Accepted Answer

Immediate centimeter-level positioning in the field without office processing

Answer

Higher vertical accuracy

Answer

Longer baseline capability

Answer

No need for a base station

Question 2

When computing the area of a closed traverse using the coordinate method, which formula is applied?

Accepted Answer

The double meridian distance (DMD) method or shoelace formula with X,Y coordinates

Answer

Heron's formula using side lengths

Answer

Simpson's one-third rule

Answer

The trapezoidal rule using offsets from a baseline

Accepted Answer

132°30'

Answer

47°30'

Answer

227°30'

Answer

Distance estimation and rod-reading redundancy for error detection

Answer

Horizontal angle precision

Answer

Magnetic declination accuracy

Answer

Vertical angle measurement

Question 5

In photogrammetric surveying, what is the purpose of ground control points (GCPs)?

Accepted Answer

To georeference the photogrammetric model to a real-world coordinate system

Answer

To define property boundaries on aerial photos

Answer

To measure atmospheric refraction corrections

Answer

To establish magnetic north for the flight path

Question 6

Which of the following best defines 'horizontal control'?
