PARTA
Answer any two full questions, each carries 15 marks.
Explain with sketch, ranging a line if the end stations are not intervisible.
The following bearings were observed on a compass traversing. At what
stations do you suspect local attraction? Find the true bearings if declination

was 1°30' W.

‎Differentiate

‎(i) declination and dip

‎(ii) latitude and departure

‎(iii) contour interval and horizontal equivalent

‎The following consecutive readings were taken with a dumpy level and a 4m
levelling staff on a continuously sloping ground on a straight line at a common
interval of 30 m. 0.855 (on A), 1.545, 2.335, 3.115, 3.825, 0.455, 1.380, 2.055,
2.855, 3.455, 0.585, 1.015, 1.850, 2.755, 3.845 (on B). The RL of A was
380.500m. Make a level field book and calculate the reduced levels of points
using Height of Instrument method and apply usual checks. Determine the
gradient of line AB.

‎Explain how the error due to curvature, refraction and collimation are
eliminated in reciprocal levelling.

‎Define contour. Explain the characteristics of contour with sketches.
