Question 1
What is the formula for calculating the Height of Instrument?
- HI = RL of BM + BS
- HI = BS - RL of BM
- HI = RL of BM - FS
💡 Hint: It's about adding the back sight reading.
Question 2
True or False: The Height of Instrument method includes checks for intermediate elevations.
- True
- False
💡 Hint: Consider the limitations we've talked about.

Challenge Problems
Push your limits with challenges.
Question 1
A surveyor records a benchmark at 75.50m. They measure a BS of 2.75m. If the FS reading at the next station is 1.95m, determine the complete elevation of the point surveyed.
💡 Hint: Use each step of HI properly to find RL.
Question 2
Explain how making errors in BS measurements can affect the final point RL in the Height of Instrument method.
💡 Hint: Consider the implications of foundational accuracy in surveying.
