Recall what we read first when setting up.
3Question 3.
What is the main purpose of differential levelling?
- To measure distances
- To find elevation differences

- True
- False
Show hintHide hint
Recall the definitions we reviewed.
Question 5.
A surveyor sets up a differential levelling task with a benchmark of 150.000 m. He records a Back Sight of 1.500 m and a Fore Sight of 0.800 m. Determine the RL of the new point.
Show hintHide hint
Apply the RL calculation formula from our session.
Question 6.
Discuss potential environmental factors that could lead to inaccuracies in differential levelling and provide solutions.
