Challenge Problems
Push your limits with challenges.
Question 1
You have a benchmark at 120.000 m. After taking a back sight of 3.250 m and a fore sight of 6.500 m, determine the RL of the unknown point and discuss potential errors.
💡 Hint: Ensure you apply the formula correctly while considering how errors can affect your result.
Question 2
In a simple levelling task, a surveyor records a BS of 1.750 m and an FS of 3.000 m with a benchmark of 80.500 m. Identify and fix any calculation errors if the calculated RL appears inconsistent.
💡 Hint: Reassess each measurement and see how they fit into the equation.
