Explain Procedure for chain and compass traversing.
by

1 Answer

Answer :

Chain and compass traversing :

1) Reconnaissance of the area to be surveyed is done.

2) Traverse stations are fixed.

3) The F.B and B.B of the traverse are measured by prismatic compass and the sides of the traverse by chain or tape.

4) Then the observed bearings are verified and necessary corrections for the local attraction are applied.

5) In this method, closing error may occur when the traverse is plotted.

6) This error is adjusted graphically by using ‘ Bowditch Rule’.
