Content covered (most frequently tested areas on the FS
exam): Surveying mathematics and statistics, trigonometry,
coordinate geometry, plane surveying principles, distance
and angle measurement, leveling, traverses, horizontal and
vertical curves, boundary and legal principles, geodesy
basics, photogrammetry, GPS/GNSS fundamentals,
mapping and coordinate systems, error analysis,
construction surveying, and data adjustment.
1. In plane surveying, the assumption made about the Earth's surface is that it is:
A. A perfect sphere
B. An ellipsoid
C. Flat over small areas
D. Irregular
Correct Answer: C. Flat over small areas
Plane surveying assumes the Earth's curvature is negligible for relatively small areas,
allowing calculations to be performed on a flat plane.
2. Which instrument is primarily used to measure horizontal and vertical angles in
surveying?
A. Level
B. Theodolite
C. Compass
D. Chain
Correct Answer: B. Theodolite
Theodolites are precision instruments designed specifically for measuring horizontal and
vertical angles in surveying operations.
, 3. The distance measured along the slope between two points is called:
A. Horizontal distance
B. Vertical distance
C. Slope distance
D. Reduced distance
Correct Answer: C. Slope distance
Slope distance refers to the direct distance measured along the inclined line between two
survey points.
4. A benchmark used as a reference point of known elevation is called:
A. Turning point
B. Control point
C. Temporary benchmark
D. Permanent benchmark
Correct Answer: D. Permanent benchmark
A permanent benchmark is a stable reference point whose elevation has been precisely
determined and documented.
5. The closing error in a traverse is primarily caused by:
A. Atmospheric pressure
B. Instrument and observational errors
C. Earth rotation
D. Magnetic declination
Correct Answer: B. Instrument and observational errors
Traverse misclosure occurs mainly due to accumulated small errors in measurement of
angles and distances.
6. In a leveling operation, the difference between backsight and foresight readings
represents:
A. Height of instrument
B. Elevation difference
C. Ground slope
D. Error correction
Correct Answer: B. Elevation difference
The difference between backsight and foresight readings determines the change in
elevation between two points.
, 7. The method used to adjust a closed traverse where corrections are proportional to line
length is called:
A. Compass rule
B. Transit rule
C. Bowditch rule
D. Least squares rule
Correct Answer: C. Bowditch rule
The Bowditch rule distributes closing error proportionally according to the length of each
traverse leg.
8. The angle measured clockwise from north in surveying is called:
A. Deflection angle
B. Bearing
C. Interior angle
D. Zenith angle
Correct Answer: B. Bearing
Bearings describe direction relative to north and are commonly expressed as angles from
north or south.
9. Which leveling method provides the highest precision?
A. Differential leveling
B. Trigonometric leveling
C. Profile leveling
D. Barometric leveling
Correct Answer: A. Differential leveling
Differential leveling provides very precise elevation differences using level instruments and
graduated rods.
10. In GPS surveying, signals are transmitted from:
A. Ground stations
B. Radio towers
C. Satellites
D. Aircraft
Correct Answer: C. Satellites
GPS uses satellites that transmit signals allowing receivers on Earth to determine precise
positions.
11. The horizontal distance corresponding to a slope distance is obtained by:
