12.5. Coordinate Computation and Adjustment

Try these first

1. 1.

   What is the horizontal distance in surveying?

   Hint

   Think about the term 'horizontal'.

2. 2.

   What does the vertical height difference represent?

   Hint

   Consider what 'height' refers to.

3. 3.

   What does HD stand for in surveying?

   • Horizontal Distance
   • Height Difference
   • Slope Distance

   Hint

   What type of distance does 'horizontal' describe?

4. 4.

   True or False: The least squares method is used to minimize errors in computed coordinates.

   • True
   • False

   Hint

   Think about how we refine measurements.

5. 5.

   You are given three point measurements with their respective horizontal and vertical coordinates. Use the least squares method to adjust them and provide a revised coordinate set.

   Hint

   Focus on minimizing the total square deviations!

6. 6.

   Given a survey loop, calculate the needed traverse closure correction when the initial coordinates do not correspond to the final return to the origin point.

   Hint

   What happens when your starting and ending points mismatch?
