5 cards from this section. Quick, good the night before a test.
What does HI stand for in surveying?
Think of what gives us the elevation point.
How do you determine the HI?
Remember, it’s like building upon a known point.
What is the formula for calculating the Height of Instrument?
It's about adding the back sight reading.
True or False: The Height of Instrument method includes checks for intermediate elevations.
Consider the limitations we've talked about.
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.
Use each step of HI properly to find RL.
Explain how making errors in BS measurements can affect the final point RL in the Height of Instrument method.
Consider the implications of foundational accuracy in surveying.
