1. In a boundary survey, the primary purpose of researching historical deeds
before fieldwork begins is to:
A. Reduce the need for field measurements
B. Determine property tax assessments
C. Establish evidence of original boundary intent and occupation
D. Eliminate the need for monument recovery
C. Establish evidence of original boundary intent and occupation
Rationale: Boundary determination relies heavily on documentary
evidence. Historical deeds, plats, and conveyances help surveyors interpret
original intent and locate boundaries accurately before collecting field
data.
2. Which principle generally carries the greatest weight in boundary
retracement?
A. Computed area
B. Bearings and distances
C. Occupation lines only
D. Original monuments
D. Original monuments
,Rationale: Original monuments established during the original survey
typically control over bearings, distances, and calculated coordinates
because they represent the physical expression of the boundary.
3. A level loop begins and ends on benchmarks of known elevation. The
difference between the measured and actual elevation change is
called:
A. Station error
B. Instrument constant
C. Closure error
D. Vertical deviation
C. Closure error
Rationale: Closure error represents the discrepancy between measured and
known elevations after completing a leveling circuit and is used to assess
survey accuracy.
4. Which type of leveling is commonly used to establish elevations with
the highest precision?
A. Trigonometric leveling
B. Differential leveling
C. Barometric leveling
D. Stadia leveling
B. Differential leveling
Rationale: Differential leveling uses precise optical instruments and
leveling procedures to achieve highly accurate elevation differences
between points.
5. The horizontal angle measured clockwise from north is known as:
A. Deflection angle
B. Interior angle
, C. Azimuth
D. Zenith angle
C. Azimuth
Rationale: Azimuths are measured clockwise from a reference meridian,
usually north, and range from 0° to 360°.
6. In a closed traverse, angular misclosure is caused primarily by:
A. Incorrect benchmark elevations
B. Errors in angle measurements
C. Atmospheric pressure changes
D. Improper map scales
B. Errors in angle measurements
Rationale: Angular misclosure results when the sum of measured angles
differs from the theoretical value due to observational or instrument
errors.
7. Which coordinate system is most commonly used for large-scale
surveying projects in the United States?
A. Polar coordinate system only
B. Geographic coordinate system only
C. State Plane Coordinate System
D. Local grid exclusively
C. State Plane Coordinate System
Rationale: The State Plane Coordinate System provides accurate horizontal
positioning over regional areas and is widely used in engineering and land
surveying.
8. The process of adjusting traverse measurements to distribute closure
error is called:
A. Calibration
, B. Rectification
C. Balancing
D. Projection
C. Balancing
Rationale: Balancing distributes measurement errors throughout a
traverse according to accepted adjustment methods such as Compass Rule
or Transit Rule.
9. Which surveying instrument directly measures slope distance and
angle electronically?
A. Dumpy level
B. Total station
C. Hand level
D. Plane table
B. Total station
Rationale: A total station combines electronic distance measurement and
angle measurement capabilities into a single instrument.
10. A benchmark is best defined as:
A. A temporary construction stake
B. A reference point of known elevation
C. A property corner monument
D. A control point with unknown coordinates
B. A reference point of known elevation
Rationale: Benchmarks serve as permanent or semi-permanent elevation
references used for vertical control in surveying.
11. What is the principal advantage of Global Navigation Satellite
Systems (GNSS) in surveying?
A. Elimination of all field checks
