Abstract
In the practice of survey and geodesic support of mining ventures the characteristics of the connection of various coordinate systems are not always known. In the article the results of applying of least squares method for coordinate system transformation are presented. Various numbers of points and their different positions on the coordinate plane are reviewed. Various cases of calculation of tentative value of transformation characteris-tics depended on the position of the pairs of points respecting each other and the other points are analyzed. The algorithm of the calculation is realized on the examples, characterizing the variants under study. The results of the research are presented in the form of tables. The transformation accuracy is given. Preliminary conclusions about the further applying of the least squares method for connecting coordinate systems are drawn.
