Procedure
1. The
position of stations were fixed as usual.
2. The
compass was centered over the station and fore bearing of line AB and BA of
line arrows taken.
3. The
line AB was chained and offsets were taken on either side of AB.
4. The
compass was removed from station A and was centered over the station B.
5. At
station B fore bearing or line of fore bearing and back bearing of AB are
taken.
6. The
line BC was chained and offsets were taken on either sides of line BC.
7. The
process was repeated till the traverse was completed.
8. The
bearing were corrected for the local attraction.
9. All the
readings was corrected for traverse in traverse table.
