S&L: Lesson 9. Levelling- description of level instruments
The foresight taken on a levelling staff held at a point between two turning points, to determine the elevation of that point, is known as intermediate sight. It may be noted that for one setting of a level, there will be only one back sight and one foresight but there can be any number of intermediate sights. Type of Levelling Equipments:

Levelling in surveying is the operation required in the determination or, more strictly, the comparison of heights of points on the surface of the earth. If a whole series of heights are given relative to a plane, this plane is called a datum. In topographical work, the datum used is the mean level of the sea because it makes the international ...
