2 ALIGNING, RANGING AND CHAINING OF A LINE Aim To measure the distance between two points on a level ground by aligning, ranging and chaining. Instrument Required 1. 2. 3. 4. 5. Chain Ranging Rod Arrows Cross staff Pegs Procedure 1. Fix the ranging rods at the given two points, where pegs are already driven on the ground. The follower stands behind station A and direct the leader with ranging rod to come in line with AB. By signals of ranging, when the ranging rod comes in the line of AB the follower direct the leader to fix ranging rod. Let the intermediate point C which should be less than 30 m. Now, the leader takes another rod and stand between A and B about 2/3 distance from A. The follower directs the leader to come line of AB by using signals of ranging, as and when the follower direct to fix the ranging rod position. Let another intermediate point D, which is less than 30 m from B. Now A, B, C and D are in one line. Now the leader and follower measure the distance. 2. 3. 4. 5. 6. Result The distance between A and B =
