 Exam Questions for Advanced Surveying Marks
 Q1 a What is tacheometric surveying? Derive the expressions for horizontal and vertical distance in the fixed hair method when the line of sight is inclined but the staff is held vertically and the measured angle is that of depression. 07 b A tacheometer was set up at station A and the following readings were obtained on a staff vertically held.Calculate the horizontal distance AB and R.L. of B., when the constants of instruments are 100 and 0.10. 07
 Q2 a What is the object of geodetic surveying? Discuss criteria for the selection of suitable figures or systems. 07 b In a triangulation survey, the altitudes of two proposed stations A & B 85 km apart, are respectively 132 and 212m. The intervening obstruction is situated at C, 60km from and has an elevation of 142m. Ascertain if A and B are intervisible and if necessary find by how much B should be raised so that the line of sight must nowhere be less than 3m above the surface of the ground. The earth’s mean radius may be taken as 3000km and the coefficient of refraction as 0.07.orTwo triangulation stations P & Q are 100km apart and have elevations 335 m and 355 m respectively. The intervening ground may be assumed to have a uniform elevation of 300m. Find the minimum height of signal required at Q so that line of sight may not pass near the ground 4 meters. 07
 Q3 a Discuss the laws of accidental errors 07 b Find the most probable values of the angles A, B, and C of the triangle ABC from the following observation equations, A = 72°30’49”, B = 64°12’21”, C = 75°24’06” 07
