CAT 2

What is the purpose of traversing in surveying?

• To measure distances between fixed points

• To establish a baseline for subsequent measurements

• To determine the positions of inaccessible points

• To establish a network of connected points

Which instrument is commonly used to measure angles in traversing?

• Altimeter

• Theodolite

• Planimeter

• Tachometer

What is the purpose of adjusting angles and distances during traversing?

• To correct for atmospheric refraction

• To ensure accuracy and closure of the traverse loop

• To account for magnetic declination

• To minimize errors in leveling

In a closed traverse, what does "closing error" refer to?

• The difference between the measured and actual distance

• The difference between the observed and calculated angles

• The discrepancy between the first and last surveyed points

• The cumulative error in the entire traverse

Which of the following errors is minimized by adjusting a traverse?

• Cumulative error

• Systematic error

• Instrumental error

• Random error

Which method is commonly used to adjust a traverse?

• Transit adjustment

• Bowditch adjustment

How can you ensure a traverse is closed with acceptable accuracy?

• By repeating the measurements multiple times

• By cross-verifying with GPS coordinates

• By adjusting angles and distances iteratively

• By comparing the sum of interior angles with the theoretical sum

Which type of traverse involves surveying along a line without returning to the starting point?

• Open traverse

In a traverse, what does the term "misclosure" refer to?

• A mistake in the calculation of distances
