Analysis of the Height Transformations of the Geodetic Plans

V diplomski nalogi obravnavamo metode določitve razlik med starim in novim državnim višinskim koordinatnim sistemom ter pretvarjanje med njima. Pretvorbe smo izvedli s pomočjo spletne aplikacije SiVis, ki omogoča dokaj enostavno in hitro transformacijo med sistemi ter na podlagi podatkov o višinah okoliških reperjev državne nivelmanske mreže. Kot podlaga za analizo smo uporabili detajlne točke treh geodetskih načrtov na različnih lokacijah v Sloveniji. Glede na rezultate pretvorb na različne načine smo ugotovili prednosti in slabosti posameznih metod. V splošnem velja, da je pretvorba višin na podlagi okoliških reperjev bolj natančna kot uporaba spletne aplikacije SiVis.The purpose of this Graduation Thesis is to understand the difference between the old and new Slovenian Height Coordinate System and to convert between those two. We did the transformations with the help of internet aplication SiVis, which enables easy and quick transformation between the two and based on the surrounding benchmark of national levelling network. The base for analysis are the points of three different Geodetic Plans around the country. The best method of transformation was then chosen according to the results of transformations. To get better results of transformation in general it is better to use the surrounding benchmarks rather than to transformate with the use of SiVis
