Analytical method of correction by Bowditch's rule can be applied either to its coordinates directly or to the departure (or latitude) of a traverse side.

(a) The corrections to the coordinates can be calculated by using

where

d X_i = Correction to X_i coordinates of a station i;

d Y_i = Correction to Y_i coordinates of a station i;

dX = total closure correction of the traverse in departure;

dY = total closure correction of the traverse in latitude;

L_i = distance from the initial station to the station i, measured along the sides of the traverse;

L = perimeter of the traverse
