301. The term “angular measurement” in surveying refers to __________.
a) Measuring the length of an angle
b) Measuring the curvature of the Earth
c) Measuring the inclination of a slope
d) Measuring the size of an angle
View Answer
Correct answer: d) Measuring the size of an angle
Explanation: Angular measurement in surveying involves determining the size of an angle between two lines or directions.
302. The horizontal distance measured along the ground is called __________.
a) Slope distance
b) Vertical distance
c) Horizontal distance
d) Line of sight distance
View Answer
Correct answer: c) Horizontal distance
Explanation: The horizontal distance is the distance measured along the ground, disregarding any vertical components.
303. The process of determining the position of an unknown point by measuring angles and distances from known points is called __________.
a) Trilateration
b) Intersection
c) Resection
d) Triangulation
View Answer
Correct answer: d) Triangulation
Explanation: Triangulation is a surveying method that involves measuring angles and distances from known points to determine the position of an unknown point.
304. Which of the following is an instrument commonly used for measuring horizontal and vertical angles in surveying?
a) Compass
b) Total station
c) Theodolite
d) Level
View Answer
Correct answer: c) Theodolite
Explanation: The theodolite is a versatile instrument commonly used in surveying for measuring both horizontal and vertical angles with high accuracy.
305. A contour line on a topographic map represents __________.
a) A straight line connecting two points of equal elevation
b) A line connecting points of equal slope
c) A line connecting points of equal distance
d) A line connecting points of equal magnetic declination
View Answer
Correct answer: a) A straight line connecting two points of equal elevation
Explanation: A contour line on a topographic map represents a straight line connecting two points of equal elevation above a reference plane.
306. The term “benchmark” in surveying refers to __________.
a) A point used for measuring distances
b) A point used for measuring angles
c) A reference point with a known elevation
d) A reference point with unknown coordinates
View Answer
Correct answer: c) A reference point with a known elevation
Explanation: A benchmark is a reference point with a known elevation, often used as a point of reference for leveling and elevation measurements.
307. What is the purpose of a leveling rod in surveying?
a) To measure horizontal angles
b) To measure vertical angles
c) To measure horizontal distances
d) To measure vertical distances
View Answer
Correct answer: d) To measure vertical distances
Explanation: A leveling rod is a graduated rod used in surveying to measure vertical distances or elevations between survey points.
308. The term “azimuth” in surveying refers to __________.
a) The vertical angle between the line of sight and the horizontal plane
b) The horizontal angle measured clockwise from the reference direction
c) The slope of a line or surface
d) The curvature of the Earth’s surface
View Answer
Correct answer: b) The horizontal angle measured clockwise from the reference direction
Explanation: Azimuth is a horizontal angle measured clockwise from a reference direction, typically the north direction.
309. The process of determining the location of an unknown point by intersecting two lines from known points is called __________.
a) Triangulation
b) Trilateration
c) Intersection
d) Resection
View Answer
Correct answer: c) Intersection
Explanation: Intersection is a surveying method where the location of an unknown point is determined by intersecting two lines from known points.
310. The process of measuring distances by direct comparison to a known baseline is called __________.
a) Triangulation
b) Trilateration
c) Ranging
d) Resection
View Answer
Correct answer: c) Ranging
Explanation: Ranging is a surveying technique where distances are measured by directly comparing them to a known baseline using visual or instrumental methods.
