Algorithm of transformation between the local system Borowa Góra and the state system PL-2000 on the example of PG Silesia

The algorithm of the transformation task obtained as a result of the realization of research concerning the accuracy evaluation and determination of coordinate transformation parameters between the local and state systems was presented. The algorithm was used practically to realize the transformation task between the local Borowa Góra system and the state system in the area of PG Silesia. Optimal transformation results were obtained using both the second-degree complex polynomial and the general-polynomial transformation of the second degree. The control of the accuracy of transformation showed that the accuracy of transformation and determination of transformation parameters is satisfactory. The above procedure proved that the two-stage transformation, which is currently in use in the mines, can be replaced by a one-step transformation conducted in accordance with the algorithm presented in the article.
