An engineer proceeded to do the stadia survey work to determine the topography of a certain area. The transit was set up at a point A, with the line of sight horizontal, took rod readings from the rods placed at B and C which is 200 m. and 60 m. from A respectively. Rod at B has stadia intercept of 2.001 m. and 0.600 m for Rod at C. a. Compute the stadia interval factor. b. Using the same instrument this was used for determining the elevation of Point D with a stadia intercept of 2.12 m. and a vertical angle of +4°22’. If the elevation of the point where the instrument was set up is 100 m., compute the elevation of Point D. Stadia constant is 0.30 m. c. Compute the horizontal distance from the point where the instrument was set up to Point D.

D with a stadia intercept of 2.12 m. and a vertical angle of +4°22’. If the
elevation of the point where the instrument was set up is 100 m., compute the
elevation of Point D. Stadia constant is 0.30 m.
c. Compute the horizontal distance from the point where the instrument was set
