This graduation thesis describes measurement of geodetic network Plaz, located on disposal site Boršt at mine Žirovski vrh. Network is being measured for purpose of monitoring disposal site's stability. Precise instrumentation was used for measurements, which allows achieving demanded below-millimeter accuracy. Theoretic foundations of used methods of measurements and measurement processing are described. The procedure and results of measurement processing are presented. Processed measurements were adjusted using least square parametric adjustment method. The results are presented graphically and with tables. Simulaton of geodetic network improvemet was also executed.
