1. Angle Condition
For a closed non-crossing loop traverse, the angle condition is:
Angle Condtion - Loop
|A loop traverse which crosses itself doesn’t have conventional “interior” angles Eqn (B-1) won’t work. Some other angle condition must be established for such cases.|
b. Deflection Angles
If deflection angles are used, the angle condition depends on how many times, if any, the traverse crosses itself.
|(a) Even crossings||(b) Odd crossings|
|Eqn (B-2)||Eqn (B-3)|
Angle condition equations are exact so the 0°, 180°, and 360° in the equations are also exact.
c. Link Traverse
In order to determine angular misclosure for a closed link traverses, directions must be known at both ends:
