http://gis.washington.edu/phurvitz/courses/esrm304/lectures/2009/Hurvitz/procedures/latitudes_and_departures.html WebAngle misclosure is calculated by comparing opening and closing directions, only if 2 Start points and 2 Close points are entered. Distance misclosure is calculated at the first Close point. The second close point will be used for angle misclosure calculations only. Traverse length is calculated from the last Start point to the first Close point.
