20.500.12556/RUL-173011 Koordinatna osnova projekta Drugega tira železniške proge Divača-Koper diplomska naloga Coordinate Basis of the Second Track Railway Project Divača–Koper graduation thesis Diplomska naloga obravnava vzpostavitev in transformacijo koordinatne osnove za projekt izgradnje Drugega tira železniške proge Divača–Koper. Zaradi uporabe različnih koordinatnih sistemov v fazi projektiranja (D48/GK) in gradnje (D96-17/TM) je bila izvedena podobnostna 7-parametrična Helmertova transformacija med sistemoma. Koordinate nove geodetske mreže, določene v D96-17/TM, je bilo treba preračunati v sistem D48/GK, da bi se zagotovila prostorska skladnost s projektno dokumentacijo. Projektno območje je bilo razdeljeno na dve transformacijski enoti, ki sta sedelno prekrivali, kar je omogočilo izvedbo primerjalne analize in dodatno preverjanje kakovosti transformacije. V nalogi so predstavljeni vhodni podatki, izračuni transformacijskih parametrov, analiza odstopanj ter grafični in numerični prikazi rezultatov. Posebna pozornost je namenjena območju Glinščica, kjer se transformacijski območji prekrivata, kar omogoča primerjalno analizo različnih transformacijskih parametrov – tako lokalnih kot tudi splošnih. Rezultati kažejo, da lokalna prilagoditev parametrov bistveno zmanjša odstopanja, medtem ko uporaba splošnih državnih parametrov povzroča enotne, a nesprejemljivo velike pomike. The thesis addresses the establishment and transformation of the coordinate reference system for the construction of the Second Track (2TDK) railroad line on the Second Track between Divača and Koper (2TDK). Since different coordinate systems were used in the planning (D48/GK) and construction (D96- 17/TM) phases, a rigorous seven-parameter Helmert similarity transformation was carried out between the two systems. The coordinates of the new geodetic control network, determined in D96-17/TM, had to be transformed to D48/GK to ensure spatial consistency with the project documentation. The project area was divided into two transformation zones that partially overlap, enabling a comparative analysis and additional quality control of the transformation. This thesis presents the input data, the computation of the transformation parameters, the analysis of the discrepancies, and graphical as well as numerical summaries of the results. Special attention is devoted to the overlap region, where the two transformation zones intersect, which allows a comparative analysis of different sets of transformation parameters – both locally adjusted and general (national) ones. The results show that the local adjustment of the parameters significantly reduces the discrepancies, while the use of general state parameters leads to uniform but unacceptably large shifts. diplomske naloge transformacija koordinat D48/GK D96-17/TM geodetska mreža analiza drugi tir Divača–Koper 2TDK graduation thesis coordinate transformation geodetic network analysis second track Divača–Koper true false false [M.
