Example of a closed-loop traverse

Below is an example of a typical closed-loop traverse in which the traverse starts and ends on the same control point:

• The starting station (1) is set on a control point with a backsight (orange line; 2) to another control point or known azimuth (3).

• The starting station then foresights (purple line; 4) to the first intermediate station (5).

• Each intermediate station in turn backsights (orange lines) the previous station and foresights (purple lines) the next station.

• The ending station (1) then backsights the last intermediate station (6) and foresights (7) the original control point (3) that was backsighted from the starting station.
