V trigonometričnih mrežah koordinatnega sistema D48/GK so bili cerkveni zvoniki določeni s koordinatami v horizontalni ravnini in večkrat tudi z višinami. Geodetske točke na cerkvenih zvonikih so služile za vzpostavljanje in umeščanje geodetskih točk v prostor. Z vzpostavitvijo koordinatnega sistema D96/TM se položaje geodetskih točk določa s pomočjo satelitskih metod geodetske izmere. Veliko geodetskih točk starih geometričnih mrež je bilo uničenih, cerkveni zvoniki pa so zaradi svoje nedostopnosti obstali in lahko služijo kot prehod med obema koordinatnima sistemoma. V magistrskem delu smo z združitvijo geodetskih GNSS in klasičnih terestričnih metod ter z izravnavo po metodi najmanjših kvadratov in s S-transformacijo določili koordinate šestim cerkvenim zvonikom na jugozahodnem delu Ljubljane. Izračunane položaje cerkvenih zvonikov smo s transformacijo primerjali s koordinatami iz starih topografij.Church belfries were determined in horizontal plane as well as the heights in the trigonometric networks of the old Slovene coordinate system D48/GK. Geodetic points on the church belfries served as reference points in detail surveying. Since the implementation of the new coordinate system D96/TM the geodetic points are determined by use of space geodetic methods and consequently church belfries are not as important as in the D48/GK era. A lot of old geodetic reference points of trigonometric networks were damaged or demolished, but church belfries are inaccessible so they remain and today serve as a transition between the old D48/GK to the new coordinate system D96/TM. In the master\u27s thesis we combined terrestrial measurements and the free-network least squares adjustment with further use of the S-transformation to determine six geodetic points of church belfries from the south-western part of Ljubljana. New coordinates were transformed to the old coordinate system and compared with the coordinates from topographies
