251. Traverse surveying is a method used to determine the _________ of a series of connected survey lines.
a) Length
b) Azimuth
c) Elevation
d) Alignment
View Answer
Correct answer: d) Alignment
Explanation: Traverse surveying is used to establish the alignment or direction of a series of connected survey lines, which helps in mapping and land surveying.
252. The starting point of a traverse is known as the _________.
a) Base point
b) Backsight point
c) Foresight point
d) Station point
View Answer
Correct answer: d) Station point
Explanation: The station point is the initial point from which the traverse starts. It serves as a reference for subsequent measurements and calculations.
253. In traverse surveying, the angle between two consecutive traverse lines is called the _________.
a) Included angle
b) Bearing angle
c) Supplementary angle
d) Vertical angle
View Answer
Correct answer: a) Included angle
Explanation: The included angle is the angle between two consecutive traverse lines, measured clockwise or counterclockwise from one line to the next.
254. The process of adjusting the measured traverse angles and distances to obtain the most probable values is known as _________.
a) Traversing
b) Balancing
c) Closing
d) Adjusting
View Answer
Correct answer: b) Balancing
Explanation: Balancing involves adjusting the measured angles and distances in a traverse survey to minimize errors and ensure closure of the traverse.
255. The method used to close a traverse and check for errors is called _________.
a) Compass rule
b) Bowditch rule
c) Latitude and departure method
d) Closing error method
View Answer
Correct answer: c) Latitude and departure method
Explanation: The latitude and departure method is used to close a traverse by comparing the accumulated latitude and departure values with the initial values. Any discrepancy indicates a closing error.
256. The ratio of the difference in latitude to the difference in departure between two consecutive traverse points is known as the _________.
a) Latitude ratio
b) Departure ratio
c) Closure ratio
d) Traverse ratio
View Answer
Correct answer: d) Traverse ratio
Explanation: The traverse ratio is the ratio of the difference in latitude to the difference in departure between two consecutive traverse points. It helps in determining the closure error in a traverse.
257. In traverse surveying, the interior angles of a closed traverse should sum up to _________.
a) 90 degrees
b) 180 degrees
c) 360 degrees
d) 720 degrees
View Answer
Correct answer: c) 360 degrees
Explanation: The sum of interior angles in a closed traverse should always be equal to 360 degrees. This is a fundamental property of closed geometric figures.
258. The process of measuring the horizontal distances between consecutive traverse points is called _________.
a) Trilateration
b) Triangulation
c) Taping
d) Ranging
View Answer
Correct answer: c) Taping
Explanation: Taping is the process of measuring the horizontal distances between consecutive traverse points using a tape measure. It is an essential step in traverse surveying.
259. A traverse is said to be closed when _________.
a) The starting and ending points coincide
b) The sum of all angles is 360 degrees
c) The sum of all distances is equal to the perimeter of the traverse
d) All measurements are within an acceptable error limit
View Answer
Correct answer: a) The starting and ending points coincide
Explanation: A traverse is considered closed when the starting and ending points coincide, indicating that the survey loop is complete.
260. The process of adjusting the lengths of the traverse lines to achieve closure is called _________.
a) Chaining
b) Levelling
c) Balancing
d) Ranging
View Answer
Correct answer: c) Balancing
Explanation: Balancing involves adjusting the measured lengths of the traverse lines to ensure closure and minimize any discrepancies between the measured and calculated distances.
