V magistrskem delu obravnavamo različne metode določitve odklona navpičnice. Obstaja več načinov pridobitve podatkov o geoidu. Na voljo so nam geopotencialni modeli na globalni, celinski in državni ravni, gravimetrična izmera in določitev geoidnih višin s kombinacijo elipsoidnih in nadmorskih višin. Uporaba določene metode določitve odklona je povezana z razpoložljivimi podatki o geoidu. V nalogi smo si kot cilj zastavili določitev odklona navpičnice z izbranimi metodami in razpoložljivimi modeli geoida. Zanimala nas je določitev odklona s kombinacijo elipsoidnih in nadmorskih višin, kjer izračunamo odklon navpičnice v točki v določeni smeri. S to metodo pridobimo odklone, ki jih lahko neposredno uporabimo v redukciji opazovanj zaradi vpliva težnostnega polja Zemlje brez poznavanja azimuta merjene smeri. Med vsemi določenimi komponentami odklona navpičnice smo izbrali vrednosti, ki smo jih uporabili pri redukciji fiktivnih (simuliranih) opazovanj. S tem smo želeli prikazati pomen uporabe ustreznih odklonov pri redukciji opazovanj in posledično pri določitvi koordinat in višine novih točk na razgibanem terenu, kot je južno pobočje Krvavca.

• Title: Analysis of deflections of the vertical in the area of test polygon Krvavec

Abstract

In this master's thesis, we discussed various methods for deflection of the vertical definition. There are various methods available for obtaining geoid information, for example, geopotential models on global, continental, and local scale, gravimetric measurements, and determination of geoid undulations with combining ellipsoidal and orthometric heights. Determination of the deflection of the vertical is linked with available geoid information. In this work, we aim to define the deflection of the vertical with selected methods and available gravimetric models. We are interested in determination the deflection of the vertical with combining ellipsoidal and orthometric heights. This method gives us deflections of the vertical at a particular azimuth. These deflections we can use directly in the reduction of measurements without calculating and using the azimuth of measured directions. For simulation, we selected some calculated values of components of deflection to use in the reduction of fictional (simulated) observations. Thereby, we want to present the importance of using suitable deflections in reductions of our observations and resulting by determination of coordinates and heights of new points on rugged terrain as is the southern slope of Krvavec.
