The master's thesis deals with the establishment of a geodetic height network on the southern slope of Krvavec from the base to the church of Marije Snežne on top. Sea level heights of points in the network were determined by means of geometric levelling and trigonometric heighting. Least squares adjustment of all measured height differences were performed, which yielded heights of all points with the corresponding accuracy. Thesis also presents a comparison of the measured geoid heights with heights determined from the geoid models 2000 and 2010. The measured geoid heights were computed as diffrences between sea level heights determined by trigonometric heighting method and ellipsoidal heights determined by RTK and the static GNSS measurement method.
