This calculator determines the area of an irregular polygon using a traverse method given side lengths and bearings in degrees. ... By substituting these values into the above formula, the correction is as follows: Since the observed elevation of the closing BM is greater than its known elevation, the adjustments are subtracted from the intermediate BMs. ; The departure of a line is its projection on the east-west meridian and is equal to the length of the line times the sine of its bearing. Top of page. difference between F.B. One is the coordinate method and the other is the Double Meridian Method(DMD.) Next, click the "Azimuth" link to toggle to Angle mode. Surveying - Traverse.
