A traverse is a series of consecutive lines whose lengths and directions have been determined from field measurements. Traversing is the act of establishing traverse stations and making the necessary measurements. It is one of the most basic and widely practiced means of determining the relative locations of points. There are two basic kinds of traverses: Closed and Open. Two categories of closed traverses exist; polygon and link. With the polygon type, the lines return to the starting point, thus forming a closed figure. Link traverses finish upon another station that has a positional accuracy equal to or greater than that of the starting point. The link type must have closing reference direction. A open traverse consists of a series of lines that are connected but do not return to the starting point or close upon a point of equal or greater order accuracy. Open traverses should be avoided because they offer no means of checking for errors and mistakes.
