Primerjava geoidnih višin v testnem poligonu Krvavec : diplomska naloga

Petovar, Blaž (author), Kuhar, Miran (mentor)

V diplomski nalogi primerjamo geoidne višine interpolirane iz uradnega modela geoida Slovenije SLOG2000, testnega izračuna novega geoida SLOG2010 ter globalnega geopotencialnega modela EGM2008 na območju juţnega pobočja Krvavca. Primerjamo tudi geoidne višine izračunane iz meritev GNSS in trigonometričnega višinomerstva. V nalogi smo predstavili tudi teoretična ozadja višinskih sistemov, geoida ter različnih metod izračuna geoida. Opisali smo posamezne modele geoidov, ki smo jih uporabili. Izračunali smo odstopanja posameznih modelov od »merjenih« vrednosti in jih ocenili po kakovosti. Iz meritev smo določili tudi potek lokalnega geoida, ki smo ga izračunali kot regresijsko ploskev.

• Title: Comparison of geoidal heights in test polygon Krvavec

Abstract

In the graduation thesis we compared geoidal heights interpolated from Slovenian national geoid model SLOG2000, preliminary calculations of new model SLOG2010 and global geopotential model EGM2008, on the southern slope of Krvavec. Also compared are geoidal heights calculated from GPS measurements and trigonometric levelling. In the thesis we also present theoretical basics of height systems, geoid and different methods of geoid determination. We described the specific geoid models used and calculated deviations of those from »measured« values, then evaluated them by quality. On the basis of measurements we calculated the local geoid plane as a regression surface.
