In the thesis the measurement of 3D geodetic network at construction pit, which is located at the railway line Ljubljana – Divača is presented. The assignment describes the surveyed area, forms of the geodetic network, stabilization and signaling of geodetic points in geodetic network. The instruments and other equipment, that we used for surveying is also presented. It is followed by the presentation of methods used for surveying horizontal and height network. We also describe distance reduction, together with calculation equations. Further on, we explain the used input data in horizontal, height and 3D geodetic network, adjustment procedure and results in GeM, ViM and Leica Infinity. In the final chapters we present the results of aligned coordinates and the precision of horizontal and height network, as for constrained and inner constrained network. The results of adjusted constrained and inner constrained network (1D, 2D and 3D), which we adjusted with the help of commercial software Leica Infinity, were compared with results in GeM, ViM and personal program for reduction calculation.
