Traversing

For locating plane table survey stations this method is used. Before shifting the table and distance ray is drawn to next station between the stations measured in this method. The distance is scaled down and next station is located. Orientation is achieved by back sighting after setting the plane table at new station. Rays are taken to other stations also, whenever it is possible to ensure additional checks. Given figure shows a scheme of plane table survey of closed area. For open traverses this method can be used also.
