SUBJECT: SURVEYING & COMPUTATION -must include diagrams & working steps according to calculation needed
SBET 1083 ASSIGNMENT: Trigonometric Heighting Below are data observed from trigonometric heighting survey obtained by using theodolite . Calculate the reduced level of station B and C and the difference in height between the two stations (B and C) . Given: Observation A -B: Height of instrument at station A = 1. 520 metre s Vertical angle between station A and B (incline) = 5  20’ 00” Height of prism at station B = 1. 550 0 metre s Reduced level at station A = 3 0.777 metre s Horiz ontal distance fr om A to B = 245. 45 5 metre s Observation A -C Height of instrument at station A = 1. 520 metre s Vertical angle between station A and C (dec line) = – 3 30’ 00” Height of prism at station C = 1. 325 metre s Reduced level at station A = 3 0.777 metre s Slope distance from A to C = 214 .524 metre s Please include diagrams in your answer. Label them appropriately and define them correctly in your calculations.
