The following consecutive readings were taken with a level and a 4m leveling staff on a continuously sloping ground at a common interval of 30 m on line AB. Chainage 0 Level Station 30 0.585 0.930 A 60 1.95 90 2.845 120 3.645 150 3.93 B The reduced level (RL) of station A is 50.00. Calculate the reduced levels at all the points where the leveling staff is placed. Tabulate the results and apply usual checks. Also determine the gradient of line AB.

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for meas…
