Q1:

Ranging in chain survey means

A looking at an isolated point not on the line

B establishing an intermediate point on the line

C determining the distance between end points

D determining the offset distance

E none of these

ANS:B - establishing an intermediate point on the line

When a survey line is longer than a chain length, it is necessary to align intermediate points on the chain line so that the measurements are along the line. The process of locating intermediate points on the survey line is known as ranging.
There are two methods of ranging; direct ranging and reciprocal ranging.
