An Intermediate sight is defined as readings which are taking just after back sight and before fore sight.

Taking of Intermediate sight (I.S): –

In levelling, after setting up of instrument first take back sight (B.S) reading on benchmark or TBM.
An intermediate sight (I.S) is staff reading taken on the points of unknown elevation.
It is done when all staff reading is visible.
When taking of more than two reading from same position, after first reading up to fore sight (F.S) all readings are intermediate sight (I.S).
