Note: Answer FIVEfull questions, selecting atleast TWO questions from each part.
PART-A :
1 a. Define mine surveying. Explain the principles of it. (08 Marks)
b. The length of a survey line was measured with a 20 m chain and was found to be equal to 1200 m. The length was again measured with a 25 m chain and was found to be 1212 m.

On comparing the 20 m chain with the test gauge, it was found to be 10 em tooling. Find the actual length of25 m chain used. (12 Marks)

a. Explain with a neat sketch, the working of optical square in chain surveying. (10 Marks)
b. In passing an obstacle in the form of a pond, station A and D, on the main line, were taken on the opposite sides of the pond.

On the left of AD, a line AB, 200 m long was lard down and a second line AC, 250 m long, was ranged on the right of AD, the points B, D and C being in the same straight line, BD and DC were then chaired and found to be 125 m and 150 m respectively. Find the length of the line AD. (10 Marks)

a. Differentiate between:
i) Bearings and angles
ii) Whole circle being and reduced being
iii) Dip and Declinators
iv) Fore bearing and beck being. (12 Marks)
b. The magnetic bearing of a line AB is S28°30’E. Calculate the true bearing if the declination is 7° 30′ West and 4° 30′ East. (08 Marks)

a. Name the various accessories used in plane table survey and explain their functions. (10 Marks)
b. Name the various methods of resection of plane table survey. Explain 3 point problem, in detail. (10 Marks)
PART-B :
a. Differentiate the foIlowing :
i) Height of a point and level of a point
ii) Back sight and fore sight
iii) Permanent benchmark and temporary benchmark
iv) Height of instrument method and rise and fall method.

b. Find the correction fro curvature and for refraction for a distance of
i) 1200 m ii) 2.48 KM.
6 a. Explain with neat sketches, the characteristics of contours.
b. Explain in detail, the uses of contour maps.

Part-A :
a. What is surveying? Write the difference between plane surveying and Geodetic surveying? List the classification based upon the nature of the field of survey. (10 Marks)

b. List the conventional instruments used in surveying. The length of line measured with a 20 m chain was found to be 634.4 m. It was afterwards found that chain was 0.05m too long. Find the true length of the line. (10 Marks)

2 a. What are the instruments Required to for taking offsets. Write the difference between oblique offset and perpendicular offset. (to Marks)

b. In passing an obstacle in the form of a pond stations A and 0, on the mainline, were taken on the opposites sides of the pond. On the left of AD, a line AB, 200 m long was laid down and a second line AC, 250 m long was ranged on the right of AD, the points B, D and C being in the same straight line, BD and DC were then chained and found to be 125 m and 150 m respectively.
