Question 1

In a closed traverse, the algebraic sum of latitudes and departures should equal:

Accepted Answer

Zero

Answer

In a geometrically closed traverse, the sum of all northing components (latitudes) and all easting components (departures) must each equal zero for perfect closure.

Question 2

The Bowditch (Compass) Rule distributes traverse closure error proportionally to:

Accepted Answer

The length of each course

Answer

The Bowditch Rule distributes linear closure error to each course in proportion to the length of that course relative to the total traverse perimeter.

Question 3

Which method is most appropriate for locating a point that is inaccessible due to an obstacle?

Accepted Answer

Intersection from two known stations

Answer

Intersection (triangulation from two or more known control points) allows a surveyor to locate an inaccessible point by measuring angles from accessible stations.

Question 4

A backsight reading of 4.52 ft and a foresight reading of 7.18 ft are taken with a level. The elevation of the foresight turning point is:

Accepted Answer

Benchmark elevation − 2.66 ft

Answer

The elevation difference is FS − BS = 7.18 − 4.52 = +2.66, so the foresight point is 2.66 ft lower than the benchmark (subtract from HI).

Question 5

In stadia surveying, the horizontal distance formula using a horizontal line of sight is:

Accepted Answer

D = K × s + C

Answer

The stadia formula for horizontal distance is D = K × s + C, where K is the stadia interval factor (typically 100), s is the rod intercept, and C is the stadia constant.
