Time: 3 Hours Max Marks: 70
Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. A line was measured with a steel tape which was exactly 30 m at a temperature of 200c and a
pull of 10 kg. The measured length was 1650 m. The temperature during measurement was 300C
and the pull applied 15 kg. Find the true length of the line, if the cross-sectional area of the tape
was 0.025 cm2. The coefficient of expansion of the material of the tape per 10 C is 3.5 x
and modulus of elasticity of the material of tape is 2.1 x 105 kg/cm2.
The following are the observed bearings of a closed traverse ABCDEA with a compass in a place
as shown in table 1.

UNIT II
3. The following staff reading was observed successively with a level, the instrument was moved
after third, sixth and eight reading: 2.230, 1.605, 0.985, 2.090, 2.845, 1.260, 0.600, 1.980, 1.045
and 2.685. Enter the above reading in a page of level book and calculate the RL of points if the
first reading was taken with staff held on bench mark of 432.385m. Adopt height of instrument
method.
With sketches describe the characteristics of contours.
4. What are the various methods of locating contours? Explain in detail
The following staff readings were observed successively with level ,the instrument having been
moved forward after the third ,sixth and eighth readings: 2.228, 1.606, 0.988, 2.090, 2.864, 1.262,
0.602, 1.982, 1.044, 2.684 metres.The first reading was taken with the staff held upon a benchmark
of elevation 432.384 m .Enter the readings in level book-form and calculate the reduced levels of
the points by rise and fall method also the gradient of the line joining the first and last point. If
the first and last points are separated by a distance of 100 m.
UNIT III
5. Derive formula to find the area of two-level section
A chain line was divided into eight sections of 12m each and off sets were taken from the chain
line to a hedge. The length of the off sets were 5.2, 7.4, 8.6, 7.9, 8.5, 8.2, 9.1 and 7.6 mts. Find
area between the chain line, boundary and first and last off sets by trapezoidal rule.
6. The following Table 3 offsets were taken from a chain line to a hedge

Offset m 3.8 3.3 2.4 1.8 0.9 1.5 1.8 2.2 3.0 3.3 3.6 2.6
Calculate the area enclosed between chain line, hedge and the end offsets by Simpson's and
trapezoidal rule.

Find out latitude and departure of the traverse and calculate the closing error if any.
8. What is closing error? What are the checks in a closed traverse.
Derive the horizontal distance between A and B and R.L of the top of the chimney when the
height of instrument at B is greater than that of A. (Instrument stations and object are in the
same vertical plane)
UNIT V
9. What is the basic principle of GPS? Explain advantages and disadvantages
Whatis meant by total station? What are the various applications of total station? Explain in
detail.
10. Briefly describe the Components and source of errors in GIS.
To determine the distance between two points A and a tachometer was setup at P and the
following observations were recorded.
Staff at A Staff readings 2.225, 2.605, 2.985 Vertical angle 7054
Staff at B Staff readings 1.640, 1.920, 2.200 Vertical angle 1046
