Solving Control Reference Azimuth Problems of Traversing Using Reorientation Traversing
Planned traverse surveys encounter setbacks when control stations are orphaned without any intervisible neighbor. This matter is made more difficult if use of Global Navigation Satellite Systems or astronomic observations are not feasible especially in built-up areas or under canopies. A control azimuth problem exists in any such cases where there are only single control stations at one or both ends of a traverse scheme. The technique of "reorientation traversing" is a simple, time- and cost-saving technique that may be used to control the orientation of traverses between reliable control stations. The reorientation traverse begins and ends with setups on the point next after and last before the initial and closing control stations, respectively, sighting to the control stations but without setting up on the control stations. The rest of the traverse is run normally. A traverse run between two nonintervisible control stations, connecting five new stations over about 1.8 km was computed using the reorientation traverse technique and also with the traditional traverse technique. The linear accuracy results were 1/176,000 and 1/101,400, respectively, showing the feasibility of the new method. Some field exercises have shown that under certain conditions the reorientation traversing would give superior results compared to the traditional traversing.
