Consider scenarios involving elevation differences.
Question 5.
You take the following readings: From A to B, you have a back sight of 3.0m and a fore sight of 4.5m. Then you move your instrument to B and get a back sight of 4.0m and a fore sight of 2.8m. Calculate the average height difference and explain the significance.
