Magistrska naloga obravnava vzpostavitev geodetske višinske mreže na južnem pobočju Krvavca od vznožja do cerkve Marije Snežne na vrhu. Novo stabiliziranim točkam so bile določene nadmorske višine z metodami geometričnega nivelmana in trigonometričnega višinomerstva. S pomočjo izravnave višinskih razlik v mreži smo določili nadmorske višine točk z pripadajočo natančnostjo. V nalogi je predstavljena tudi primerjava izmerjenih geoidnih višin z geoidnimi višinami modelom geoida 2000 in 2010. Izmerjene geoidne višine smo pridobili s pomočjo nadmorskih višin določenih s postopkom trigonometričnega višinomerstva ter RTK in statično metodo GNSS izmere.

• Title: Establishment of geodetic height network and analysis of geoid heights in the area of Krvavec : Master thesis

Abstract

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.
