This paper discusses the precision of computational resection on the experimental basis. Computational resection was recently developed by the authors for the CAD-based plane table surveying system, which is a on-line ground survey system linking a total station to a PC directly. Computational resection is used for free-stationing. Its precision is governed by mechanical precision of a total station, configuration of sight points and many other factors. Nominal values of the mechanical precision is usually given by manufactures. This paper shows the experimental test result on the precision of a total station. A 2-D network of control points is made and an instrument point set on one of them is determined by computational resection. Then the predetermined coordintes and those calculated by resection are compared. The result shows the quality of the total station is excellent enough for free-stationing by computational resection.
