Bowditch rule

This rule also termed as compass rule.

It is used to balance the traverse when angular and linear measurements are equally precise.

It is the rule most commonly used in traverse adjustment.

Correction to latitude or departure to any side = total error in latitude and departure $\times \frac{\text{length of that side}}{\text{perimeter of traverse}}$

Modified transit rule

Correction to the northing of side = $\frac12 \text{total error in latitude} \times \frac{\text{sides northing}}{\text{arithmatical sum of all the latitude}}$
