equivalent, factors effecting contour interval, characteristics of contours,

methods of contouring: Direct and indirect, interpolation of contours; use of

contour map, Drawing cross section from a contour map; alignment of a

road on contour map, computation of earth work and reservoir capacity from

a contour map.

2. Theodolite Surveying: (14 Hrs.)

Working of a transit vernier theodolite, axes of a theodolite and their relation;

temporary adjustments of a transit theodolite; concept of transiting,

swinging, face left, face right and changing face; measurement of horizontal

and vertical angles. Prolonging a line (forward and backward) measurement

of bearing of a line; traversing by included angles and deflection angle

method; plotting a traverse; concept of coordinate and solution of omitted

measurements (one side affected), errors in theodolite survey.

Height of objects – accessible and non-accessible bases

3. Tacheometric surveying: (10 Hrs.)

Tacheometry, Instruments to be used in tacheometry, methods of

tacheometry, stadia system of tachometry, general principles of stadia

tachometry, examples of stadia tachometry and Numerical problems.

4. Curves: (14 Hrs.)

4.1 Simple Circular Curve:

* Need and definition of a simple circular curve; Elements of simple

circular curve - Degree of the curve, radius of the curve, tangent

length, point of intersection (Apex point), tangent point, length

Setting out of simple circular curve (No derivations, only brief description):

a) By linear measurements only:

- Offsets from the tangent

- Successive bisection of arcs

- Offsets from the chord produced

b) By tangential angles using a theodolite (with numerical problems)
