WebThe following two ways by which Trigonometric Leveling can be done: Observations taken for the height and distances. Geodetic Observations. In the first type, if accessible the horizontal distance between the given points can be measured. The observation of the vertical angles is taken into account using which we can compute the distances. WebD= the length of the sight or the distance from the instruments to the staff station in kilometers BC= he error due to curvature. O= the center of the earth. ADVERTISEMENTS: R= the radius of the earth. By Geometry, BC x BE =BA 2 Or BC (BC= CE) = BC 2 Or BC 2 +BC x CE=BA 2 ADVERTISEMENTS:

WebExample 1: The magnetic bearing of a line is 197°. Find its true bearing, it the magnetic declination is 3° W. Solution: Since the magnetic meridian is deflected towards west of the true meridian, true bearing of the line, = the magnetic bearing – declination = 197° – 3° = 194° (Ans.)
