1. Which surveying method is primarily used to establish horizontal
control over large areas?
A. Differential leveling
B. Traversing
C. Hydrographic surveying
D. Photogrammetry
Answer: B. Traversing
Rationale: Traversing is a fundamental method for establishing
horizontal control by measuring angles and distances between survey
stations. It is widely used in boundary, topographic, and engineering
surveys because it provides accurate coordinate positions over
extensive areas.
, 2. The primary purpose of differential leveling is to determine:
A. Horizontal distances
B. Property boundaries
C. Elevation differences
D. Magnetic declination
Answer: C. Elevation differences
Rationale: Differential leveling measures vertical differences in
elevation between points using a level instrument and graduated rod.
It is commonly employed in construction, drainage, and topographic
projects.
3. Which instrument directly measures horizontal and vertical
angles?
A. Level
B. Total Station
C. Tape
D. Planimeter
Answer: B. Total Station
Rationale: A total station combines an electronic theodolite and
distance meter, allowing precise measurement of both angles and
,distances. It is one of the most versatile instruments in modern
surveying.
4. What is the standard unit for angular measurement in most
surveying computations?
A. Radians only
B. Degrees, minutes, and seconds
C. Meters
D. Feet per second
Answer: B. Degrees, minutes, and seconds
Rationale: Surveying traditionally uses degrees, minutes, and seconds
(DMS) for angular measurements because they provide a convenient
and precise way to represent angles in field observations and legal
descriptions.
5. A benchmark is best defined as:
A. A temporary survey point
B. A known elevation reference point
C. A property corner
D. An angle measurement station
, Answer: B. A known elevation reference point
Rationale: Benchmarks provide fixed elevations referenced to a
datum. They serve as control points for leveling operations and ensure
consistency across projects.
6. Which error increases proportionally with the length of a tape
measurement?
A. Personal error
B. Instrument centering error
C. Systematic tape error
D. Reading interpolation error
Answer: C. Systematic tape error
Rationale: Systematic tape errors such as incorrect tape length,
temperature effects, or tension errors accumulate proportionally as
measurement distances increase.
7. Magnetic declination is the angle between:
A. True north and magnetic north
B. Grid north and south
