How do you calculate c correction in traverse?

To calculate the c correction in a traverse, you first determine the error of closure by comparing the computed coordinates of the traverse's starting and ending points. The c correction is then calculated by dividing the total error in the traverse by the total distance or the number of sides of the traverse, depending on the method used. This correction is then applied uniformly to each traverse leg to adjust the measured angles or distances, ensuring that the traverse closes accurately.
