1.15. Example 1.33: Length and Bearing of Missing Traverse Leg

Try these first

1. 1.

   Define latitude and departure in surveying.

   Hint

   Think of navigating on a grid.

2. 2.

   What does a closed traverse ensure?

   Hint

   Recall the concept of closure in mathematics.

3. 3.

   What is the main purpose of traverse closure?

   • To ensure accurate measurements
   • To calculate area
   • To fit the compass readings

   Hint

   Think about why surveying needs to be precise.

4. 4.

   True or False: Latitude must always equal departure in a traverse.

   • True
   • False

   Hint

   Consider the definition of latitude and departure.

5. 5.

   In a closed traverse ABCD, where AB = 100m at a bearing of 0º, BC = 200m at 90º, CD = 150m at 180º; calculate the length and bearing of DA.

   Hint

   Remember to apply trigonometry for the missing leg computations.

6. 6.

   Given a traverse that does not close with an error of 2m, explain how you would apply the Bowditch method to resolve this issue.

   Hint

   Refer to our earlier calculations for guidance!
