Question 1

What is 'differential leveling' used to determine?

Accepted Answer

Elevation differences between two or more points

Answer

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

Question 2

In a survey traverse, 'closure error' refers to:

Accepted Answer

The failure of a traverse to return exactly to its starting point

Answer

Closure error is the discrepancy between the computed and actual end point of a closed traverse, indicating accumulated measurement errors.

Question 3

What is the magnetic declination?

Accepted Answer

The angle between true north and magnetic north at a given location

Answer

Magnetic declination is the horizontal angle between geographic (true) north and magnetic north, which varies by location and changes over time.

Question 4

Which of the following best describes a 'benchmark' in surveying?

Accepted Answer

A permanent point of known elevation used as a vertical reference

Answer

A benchmark is a stable, permanent marker of precisely known elevation that serves as a reference for leveling surveys.

Question 5

The 'rod reading' in differential leveling is the value observed on the:

Accepted Answer

Stadia rod held vertically at a survey point

Answer

The rod (or level rod) is a graduated staff held vertically at a point, and its reading through the level telescope gives the height of the instrument above that point.
