EXERCISES (6.1) In a closed traverse ABCDEFA the angles and lengths of sides were measured and, after the 1. angles had been adjusted, the traverse sheet shown below was prepared. It became apparent on checking through the sheet that it contained mistakes. Rectify the sheet where necessary and then correct the coordinates by Bowditch's method. Hence, determine the co- ordinates of all the stations. The coordinates of A are E-235.5, N+1070.0. ?
