A dumpy level with an internal focusing telescope was set up on the left bank of a river and the rod readings tabulated below were taken on a stadia rod held successively at the left and right water edges. If the stadia interval factor of the instrument is 100 and the stadia constant is 0.30m, determine the width of the river. Rod held at LWE: Upper Reading = 2.190 m & Lower Reading = 2.155 m Rod held at RWE: Upper Reading = 2.275 m & Lower Reading = 2.070 m
1 - A, B and C are three triangulation stations whose positions were determined by the angle measured at station B to A and C, respectively. The distance BC was measured to be 1200 m long and CD is 965 m long. The azimuth of C from B is 140° and that of A from B is 286°30’. A sounding at F (south of three stations) was taken from a boat and the angle BFA and BFC were measured simutaneously by two sextants from the boat to the three stations ABC as 22°30’ and 28°15’, respectively. How far is F from B?
