A trigonometric levelling conducted by Mat. Geo Pezyn surveying company. The two points A and B of a certain rough terrain are each distance 2000m from a point C form which the measured vertical angles to A is +3 deg. 30 min. and to B +1 deg. 30 min. Elevation C is known to be 346.16 m above sea level point C is in between A and B. A. Compute the difference in elevation between A and B considering the effect of the earth’s curvature and refraction B. Compute the difference in elevation between B and C Compute the elevation of A
