Question 1

Consider the following statements associated with triangulation survey
1) In triangulation survey unknown distances between stations are determined using Tacheometric relations
2) The triangulation station at which astronomical observations are made for azimuths are called Laplace stations
3) In tertiary triangulation, the length of the sides is in the range of 10 to 25 km
4) The length of the base line in primary triangulation is 8 to 12 km
Of these statements

Question 2

In a levelling survey, the summation of all backsights and the summation of all foresights are 7.475 m and 7.395 m respectively. The reduced level of the initial benchmark is 100 m. The reduced level
of the last point where the staff is held will be

Question 3

Group-I lists tool/instrument while Group -II lists method of surveying. Match the tool/instrument with the corresponding method of surveying

Question 4

Setting out a curve using two theodolite methods involves with

Question 5

A parabolic vertical curve is to be set out connecting two uniform grades of + 0.6% and + 1.0%. The rate of change of grade is to be 0.06% per 30 m. The length of the curve will be

Question 6

If the 20m chain is used to set out a 40 curves, then the radius of the curve is______________

Question 7

The length of a transition curve for a circular curve of radius 300 m and for a design speed of 15 m/s, when the rate of change of centrifugal acceleration is 0.3 m/s3 is

Question 8

Match List-I with List-II and select the correct answer using the codes given below the lists
List – I (Elements of aerial photographs)
A) Perspective centre
B) Plumb point
C) Principal point
D) Isocentre
List-II
1) The point where the perpendicular from the optical centre of the lens meets the photograph
2) The point where the rays from the objects converge
3) The point where the vertical through the optical centre meets the photograph
4) The point where the horizontal through optical centre meets the photograph
5) The point where the bisector of the angle between vertical and perpendicular from optical centre meet the photograph

Question 9

If the focus length of the object glass is 25 cm and the distance from object glass to the trunnion axis is 15 cm. The additive constant is

Question 10

In a closed traverse, “latitude” & “departures” of the sides were calculated & it was observed that
SL = 0.7 & SD = -2.8
Then the bearing of the closing error is
