Sažetak

In the tunnelling is necessary to provide the breakthrough accuracy not only horizontally but also in terms of height. With tolerances in breakthrough point are defined parameters to calculate the coordinates of geodetic control points. In order to transfer the height to the tunnel, because of construction of underground structures, it is necessary to develop altitude geodetic basis on the surface near to the tunnel. By creating of the new Geoid model HRG2009 have been created the preconditions to consider the possible application of HRG2009 Geoid to calculate the height of the network points, or to serve as an independent check of the height defining.
