Document Summary
A series of consecutive lines whose lengths and directions are determined from field survey. Closed traverses are consecutive lines that begin and end in points of known coordinates: when initial and final points are the same, this closed traverse is called a loop traverse. Open traverses do not end in a point of known coordinates. Angle misclosure = measured sum - theoretical sum. K = constant that depends on the level of accuracy specified for the survey. Sources of error in traversing: poor selection of stations, resulting in bad sighting conditions, errors in observations of angles and distances, failure to observe angles an equal number of times direct and reversed.
