@masteredgeacademy: Understanding Leveling & Its Calculations - Part 1 How does leveling work in surveying? And how do you calculate HI and RL from your field readings? In this Part 1 tutorial, we go from the field observation to the actual calculations. You’ll see how a surveyor takes: ➡️ BS = 1.20 m on a TBM ➡️ IS = 1.16 m at Point 1 ➡️ IS = 2.01 m at Point 2 ➡️ FS = 1.90 m at Point 3 Then we calculate: HI = RL + BS and RL = HI − IS/FS By the end, you’ll understand why the HI remains constant when the instrument stays in the same position, while different staff readings produce different RLs. #survey #level #student #masteredgeacademy
