281. The process of calculating the latitude and departure for each traverse leg is known as __________.
a) Adjusting the traverse
b) Balancing the traverse
c) Reducing the traverse
d) Closing the traverse
View Answer
Correct answer: c) Reducing the traverse
Explanation: Reducing the traverse involves calculating the latitude (north-south component) and departure (east-west component) for each traverse leg to determine the closing error.
282. The closure error in a traverse survey is caused by __________.
a) Instrument errors
b) Measurement errors
c) Natural features
d) Human errors
View Answer
Correct answer: b) Measurement errors
Explanation: The closure error in a traverse survey is primarily caused by errors in measuring angles and distances.
283. The method used to distribute the closure error proportionally to the traverse stations is called __________.
a) Compass rule
b) Bowditch’s rule
c) Transit rule
d) Latitude rule
View Answer
Correct answer: b) Bowditch’s rule
Explanation: Bowditch’s rule is a method used to distribute the closure error proportionally to the traverse stations, ensuring that the error is evenly distributed.
284. The ratio of the distance between two points on the ground to their horizontal distance measured on a map or plan is known as the __________.
a) Scale factor
b) Correction factor
c) Reduction factor
d) Expansion factor
View Answer
Correct answer: a) Scale factor
Explanation: The scale factor represents the ratio between the ground distance and the corresponding distance on a map or plan. It is used to convert between the two distances.
285. The purpose of a plotting scale in surveying is to __________.
a) Determine the accuracy of the plot
b) Enlarge or reduce the size of the plot
c) Determine the grid coordinates of the plot
d) Determine the scale factor of the plot
View Answer
Correct answer: b) Enlarge or reduce the size of the plot
Explanation: A plotting scale is used to adjust the size of the plot, either enlarging or reducing it to fit a specific size or paper.
286. The method used to transfer points from the field to a drawing or plan is called __________.
a) Scaling
b) Plotting
c) Tracing
d) Dimensioning
View Answer
Correct answer: b) Plotting
Explanation: Plotting involves transferring the survey measurements and points from the field to a drawing or plan, ensuring accurate representation of the surveyed area.
287. The process of entering survey data, including measurements and observations, into a survey field book is called __________.
a) Logging
b) Recording
c) Noting
d) Tabulating
View Answer
Correct answer: b) Recording
Explanation: Recording involves entering the survey data, such as measurements, observations, and notes, into a survey field book for future reference and analysis.
288. The purpose of leveling a survey instrument before taking measurements is to __________.
a) Ensure accuracy in angle measurements
b) Determine the true north direction
c) Establish the elevation of a point
d) Verify the accuracy of the instrument
View Answer
Correct answer: a) Ensure accuracy in angle measurements
Explanation: Leveling the instrument ensures that it is properly aligned and leveled, providing accurate angle measurements.
289. The process of checking the vertical alignment of a leveling instrument by comparing the readings at a benchmark is called __________.
a) Benchmarking
b) Cross-checking
c) Differential leveling
d) Check leveling
View Answer
Correct answer: d) Check leveling
Explanation: Check leveling involves comparing the readings at a benchmark to ensure the accuracy and alignment of the leveling instrument.
290. The purpose of setting up a temporary benchmark in surveying is to __________.
a) Provide a reference point for future surveys
b) Measure the elevation difference between two points
c) Determine the true north direction
d) Establish the elevation of a point
View Answer
Correct answer: a) Provide a reference point for future surveys
Explanation: A temporary benchmark is set up to serve as a reference point for future surveys, providing a known elevation for future measurements.
