SMQT Fundamentals of Surveying 2

Question 1

What is the primary purpose of a control survey?

Accepted Answer

To establish a network of accurately located points used as a reference framework

Answer

Control surveys establish precise horizontal and/or vertical reference points (control points) that other surveys are tied to for consistency and accuracy.

Question 2

Which angle measurement system divides a circle into 400 equal units?

Accepted Answer

Gradians (Grads)

Answer

The gradian (grad) system divides a full circle into 400 grads, with a right angle equaling exactly 100 grads.

Question 3

What does 'differential leveling' determine?

Accepted Answer

Elevation differences between two or more points

Answer

Differential leveling uses a level instrument and rod readings to determine the difference in elevation between a benchmark and other points.

Question 4

In surveying, what is a 'backsight'?

Accepted Answer

A measurement taken toward the rear of the survey line to a known point

Answer

A backsight is a rod or angle reading taken on a point of known elevation or position, used to establish the instrument's position or elevation.

Question 5

What is the closure error in a closed traverse?

Accepted Answer

The difference between the computed and known position of the final point

Answer

Closure error is the linear distance between the computed ending position and the actual starting point of a closed traverse, indicating accumulated survey error.
