Experiments:
1. a) Measurements of distances using tape along with horizontal planes and slopes, direct ranging. b) Setting out perpendiculars. Use of cross staff, optical square
2. Obstacles in chaining and ranging – Chaining but not ranging, ranging but not chaining, both ranging and chaining.
3. Measurements of bearings / directions using prismatic compass, setting of geometrical figures using prismatic compass.
4. Measurement of bearings of sides of a closed traverse and adjustment of closing error by Bowditch method.
5. Determination of distance between two inaccessible points using compass and accessories
6. Determination of reduced levels of points using dumpy level/auto level (simple leveling)
7. Determination of reduced levels of points using dumpy level/auto level (differential leveling and inverted leveling)
8. To determine the difference in elevation between two points using Reciprocal leveling and to determine the collimation error
9. To conduct profile leveling, cross sectioning and block leveling. Plotting profile and cross sectioning in excel. Block contour on graph paper to scale
10. Measurement of horizontal angle by repetition and reiteration methods and Measurement of vertical angles using theodolite.
11. Determination of horizontal distance and vertical height to a base inaccessible object using theodolite by single plane and double plane method.
12. To determine distance and elevation using tachometric surveying with horizontal and inclined line of sight.
13. Closed traverse surveying using Theodolite and applying corrections for error of closure by transit rule.
14. Demonstration of Minor instruments Clinometer, Ceylon Ghat tracer, Box sextant, Hand level, Planimeter, nautical sextant and Pentagraph
