Fundamentals of Surveying: Please show your solution. The backsight reading on a point is 9.35 m and the foresight reading on a second point is 0.86 m. If the elevation of the first point is 409.25 m, determine the elevation of the second point.
Can differential leveling be combined with trigonometric leveling in an adjustment? Explain how you would handle their relative qualities in a least squares analysis? Explain properly.
