1. A survey crew measures a horizontal distance with a steel tape that is
standardized at 68°F. During the survey, the temperature is 88°F. If no
temperature correction is applied, the measured distance will most likely
be:
A. Too short
B. Too long
C. Correct
D. Zero
Answer: B
Explanation: A warmer tape expands, making each tape length longer than its
standard length. The measured distance is therefore recorded as longer than the
true distance.
2. Which instrument is primarily used to measure horizontal and vertical
angles with high precision?
A. Automatic level
B. Total station
C. Measuring wheel
D. Hand compass
,Answer: B
Explanation: A total station combines an electronic theodolite and electronic
distance measurement (EDM) capabilities.
3. In California engineering surveying, a benchmark is best defined as:
A. A temporary flag
B. A point of known elevation
C. A property corner
D. A traverse station
Answer: B
Explanation: Benchmarks provide known elevations used for vertical control.
4. Which adjustment method is commonly used for balancing a closed
traverse when measurements have similar precision?
A. Bowditch (Compass Rule)
B. Simpson's Rule
C. Newton's Method
D. Least Squares Only
Answer: A
Explanation: The Bowditch Rule distributes closure error proportionally according
to line lengths when measurements are of comparable accuracy.
5. What is the primary purpose of backsight observations?
A. Measure property boundaries
B. Establish instrument orientation
C. Determine slope distance
D. Locate utilities
Answer: B
,Explanation: A backsight establishes the instrument's direction before additional
observations are made.
6. Which coordinate system is commonly used for engineering surveys in
California?
A. Universal Polar Grid
B. California Coordinate System
C. Military Grid Only
D. Local Latitude System
Answer: B
Explanation: The California Coordinate System provides standardized plane
coordinates for surveying.
7. If the foresight rod reading is greater than the backsight rod reading, the
next point is:
A. Higher
B. Lower
C. Same elevation
D. Unknown
Answer: B
Explanation: A larger foresight reading indicates a lower ground elevation.
8. EDM instruments primarily measure:
A. Vertical angle
B. Horizontal angle
C. Distance using electromagnetic waves
D. Magnetic declination
Answer: C
, Explanation: Electronic Distance Measurement instruments determine distance
using electromagnetic signals.
9. The sum of interior angles of a six-sided closed traverse should equal:
A. 540°
B. 720°
C. 900°
D. 1080°
Answer: B
Explanation: The formula is (n − 2) × 180°. For six sides: (6 − 2) × 180° = 720°.
10.A leveling loop fails to close by 0.04 ft. This value is known as:
A. Instrument constant
B. Closure error
C. Index error
D. Prism constant
Answer: B
Explanation: Closure error represents the difference between the computed and
known ending elevation.
11.Which measurement is least affected by magnetic declination?
A. Compass bearing
B. Magnetic azimuth
C. Grid bearing
D. Hand compass reading
Answer: C
Explanation: Grid bearings are based on the coordinate system rather than
magnetic north.
