A dumpy level is set up with its eye-piece vertically over a peg . The height from the top of peg to the centre of the eye-piece is 1.540 m and the reading on peg is 0.705 m. The level is then setup over . The height of the eye-piece above peg is 1.490 m and a reading on is 2.195 m. The difference in level between and is"

Surveying and leveling is a measurement process that determines the height of the level and the distance of an area with another elevated surface.

The principle of levelling is to obtain a horizontal line of sight at which the vertical distance of a point above or below this line of sight is found.

The main purpose of balancing in the survey is: Find the heights of the given points in relation to the given data.
