Question 1

In plane surveying, which coordinate system is commonly used in the United States for state-based mapping?

Accepted Answer

State Plane Coordinate System (SPCS)

Answer

The State Plane Coordinate System (SPCS) is a set of 124 geographic zones used in the United States for high-accuracy surveys at the state and local level.

Question 2

What is the purpose of a bench mark (BM) in surveying?

Accepted Answer

To serve as a permanent reference point of known elevation

Answer

A bench mark is a permanent, stable monument with a precisely determined elevation used as a reference point for leveling surveys.

Question 3

Which error in leveling surveys accumulates proportionally to the square root of the distance traveled?

Accepted Answer

Random error

Answer

Random errors in leveling accumulate in proportion to the square root of the number of setups or distance, following statistical principles of error propagation.

Question 4

The magnetic declination in surveying accounts for the difference between which two directions?

Accepted Answer

True north and magnetic north

Answer

Magnetic declination is the angle between true (geographic) north and magnetic north at a given location, which varies with location and time.

Question 5

In route surveying, a simple circular curve is defined by which primary parameter?

Accepted Answer

Radius or degree of curvature

Answer

A simple circular curve is primarily defined by its radius R (or equivalently, the degree of curvature D), from which all other curve elements are derived.
