Question 1.
What is a closing error in surveying?
Show hintHide hint
Think about where the traverse begins and ends.
Question 2.
What does a bearing represent?
Show hintHide hint
Consider how angles are defined on a compass.
3Question 3.
What is the primary purpose of adjusting a closed traverse?
- To change the starting point
- To correct measurement errors
- To increase measurement accuracy
Show hintHide hint
Think about the goal of accurate surveying.
4Question 4.
True or False: The sum of interior angles in a closed traverse should equal (2n - 4) x 90°.
- True
- False
Show hintHide hint
Consider the relationship between the sides of the traverse.
Question 5.
In a closed traverse with five sides, the computed angles summed to 401°. Calculate the angular error and describe how to adjust it for each angle.
Show hintHide hint
Apply the adjustment slowly to see the overall effect.
Question 6.
During a traverse, you find the sum of latitudes is +6.5m while departures sum up to -3.0m. If applying the Bowditch rule, calculate the adjustment for a side of 50m.
