Determine vertical deflection at point D.
In the two-peg of a dummy level, the following observation are taken. What is the difference in elevation between A and B? Answer: ____________ If the line of sight is not in adjustment, determine the correct rod reading on B with the instrument still set up at A. Answer: ____________
Please help with b, i & ii The slope distance between two stations A and B measured with EDM when corrected for meteorological conditions and instrument constants, is 113.893 m. The heights of the instrument and reflector are 1.739 m and 1.839 m, respectively, above the ground. To measure the vertical angle a theodolite was set up at A, 1.665 m above the ground and a target at B having height above the ground as 1.632 m. The measured angle above the horizontal was + 4°22′18″. Determine a. The horizontal length of the line AB. b. To what precision the slope angle be measured: i. if the relative precision of the reduced horizontal distance is to be 1/100000. ii. if the reduced horizontal distance is to have a standard error of ± 1.8 mm.
