Elaboration of geodetic control network at construction of bridge over Vistula River in Pulawy

In this paper the method of geodetic control network elaboration is presented. That network consists of GPS vectors and distances measured classically. The method of reduction of GPS vectors from WGS84 to local coordinate system was described. Common adjustment of GPS vectors and distances in a local coordinate system was performed. The observations set was obtained from measurements of geodetic control network at the construction site of bridge over Vistula River in Pulawy.
