Regulacja trawersu

Consider that a traverse with four sides is plotted based on the field measurements taken during a site survey.

First, the internal angles of the traverse are calculated and summed, yielding 359 degrees and 48 minutes.

To achieve an accurate four-sided traverse, the sum of the internal angles must be 360 degrees. The shortfall of 12 minutes indicates an error in recording or measuring the readings during the fieldwork.

To correct this error and ensure accuracy, the discrepancy is adjusted by distributing the 12-minute error equally among all four internal angles of the traverse, resulting in an addition of three minutes to each angle.

After adjustment, the summation of the corrected angles equals 360 degrees, which confirms the accuracy of the correction.

Finally, the magnetic bearing for side AB is obtained on the field as the starting point, and the new bearings for the remaining sides are calculated using the corrected internal angles as references.
