What is the primary purpose of adjusting a closed traverse?
💡 Hint: Think about the goal of accurate surveying.

Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Apply the adjustment slowly to see the overall effect.
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.
💡 Hint: Break it down to the error per unit length.
