Types Frequently in surveying engineering and geodetic science, control points (CP) are setting/observing distance and direction (bearings, angles, azimuths, and elevation). The CP throughout the control network may consist of monuments, benchmarks, vertical control, etc. There are mainly two types of traverse: Closed traverse: either originates from a station and returns to the same station completing a circuit, or runs between two known stations  Open traverse: neither returns to its starting station, nor closes on any other known station. 250px|Diagram of an open traverse 250px|Diagram of a closed traverse Compound A compound traverse is where an open traverse is linked at its ends to an existing traverse to form a closed traverse. The closing line may be defined by coordinates at the end points which have been determined by previous survey. The difficulty is, where there is linear misclosure, it is not known whether the error is in the new survey or the previous survey.
