Measurements of bearings of traverse legs

The travers stations may be selected clockwise or anticlockwise order. But the direction of the traverse should be indicated ill the index sketch. Suppose four traverse stations A,B,C, and D are selected to enclose an area. The prismatic compass is centered and leveled at the starting station at A. the fore bearing of AB and back bearing od DA at taken from this station. . Technical Data used in the field explained in civil surveyor course in rawalpindi. The distance AB is measured and offsets are taken alone the line AB and recorded in field book.

The compass is then shifted and centered over station B. then the FB of BC and BB of AB are taken. here , the FB and BB of line AB should differ by exactly 180 degree. Some more details of civil surveyor course in rawalpindi are as under. However, the error should not exceed the permissible limit. If it does, the bearings of the line should be observed again.

Now, the line BC is measured and offsets are taken and noted in the field book. After completion of the work ,the observations are tabulated and necessary corrections applied to eliminate the effect of local attraction. The following are the various methods of plotting compass traverse. The starting point A is suitably selected on the paper and a line representing the north line. .
