The method consists in measuring the line in short horizontal lengths called steps. Suppose it is required to measure the horizontal distance between the points A and B (Fig. 2.19). For convenience and to obtain better results, chaining is done from top of hill to the toe i.e. downhill.

ADVERTISEMENTS:


The follower holds the zero end of the chain at A on the ground and the leader with the other handle of the chain and a ranging rod moves in the forward direction at a convenient distance apart.

The leader then stops and the follower directs him to be in line with B. The leader then stretches the chain in the horizontal position and transfers the end point of the chain on the ground with the help of a plumb-bob or ordinarily with a ranging rod or by dropping a piece of stone.

The follower then moves and reaches the station occupied by the leader and then the leader moves in the forward direction. The process is repeated for several times until the whole line is chained. The lengths of all the steps are added up so as to obtain the total horizontal distance. In this case, the horizontal distance between AB = Ap + Pq + Qr + Rb.

I like this method but why is it always demonstrated as going down grade. Are there no examples of how to do this going up grade? That is what I need to do, start at a known point and survey upgrade to another point that cannot be started form.
