Levelling In Surveying Types Of Levelling Objectives ...

The basic principle of levelling is to determine the horizontal line of sight with respect to which the vertical distances of the points below or above this line of sight are determined. In general, two types of levelling are used in engineering works i.e. direct levelling (spirit) and indirect levelling (trigonometric).
