❓ Frequently Asked Questions
What is traverse adjustment in surveying?
Traverse adjustment is a surveying process used to correct errors in measured angles and distances to achieve closure in a traverse survey. It distributes misclosure errors proportionally across all traverse lines using methods like Bowditch Rule or Transit Rule.
What is the difference between Bowditch Rule and Transit Rule?
Bowditch Rule (Compass Rule) assumes equal precision in angles and distances, distributing corrections proportional to line lengths. Transit Rule assumes higher precision in angles than distances, distributing corrections based on latitude and departure values.
How do you calculate closure error in traverse?
Closure error is calculated as the square root of (sum of latitudes)² + (sum of departures)². Linear misclosure = √(ΣL² + ΣD²), where L is latitude and D is departure.
What is acceptable precision for traverse surveys?
Acceptable precision varies by survey type: 1:5,000 for preliminary surveys, 1:10,000 for property surveys, and 1:20,000 or better for precise control surveys. Higher ratios indicate better precision.
