Q. 1 All questions are compulsory (20M)

a) Distinguish between land survey and construction survey.

b) Distinguish between digital level and auto-level

c) Distinguish between block contouring and radial contouring.

d) Distinguish between conventional theodolite and electronic theodolite.

Q. 2. (a) Explain with neat sketch various elements of the simple curve and also derive the relation between the degree of the curve and its radius. (10M)

b) Explain the stepwise procedure to check the verticality of the building. (10M)

Q. 3 a) Two tangents intersect at a chainage of 1230m the deflection angle being 30˚ calculate all the data required for setting out a simple circular curve of 330m radius by Rankine’s method. (10M)

b) What is GPS? What are the advantages of a space-based positioning system and enlist the various applications of GPS in surveying.(10M)
