Določitev višinske transformacijske ploskve na izbranih območjih Slovenije : diplomska naloga

Kobale, Žiga (author), Koler, Božo (mentor), Urbančič, Tilen (co-mentor)

V diplomski nalogi smo obravnavali problem transformacije med višinskima sistemoma SVS2000 (datum Trst) in SVS2010 (datum Koper). Zamik med višinskima sistemoma po celotnem območju Slovenije ni konstanten, zato v Sloveniji še ne poznamo enotnega modela transformacije. V diplomski nalogi smo tako določili lokalno višinsko transformacijsko ploskev, in sicer na območju Prekmurja. Kot vhodne podatke za izdelavo višinske transformacijske ploskve smo uporabili razlike višin reperjev nivelmanske mreže Slovenije. Analizirali smo vpliv različnih interpolacijskih metod, vpliv uporabe različnih redov nivelmanskih reperjev in vpliv velikosti določitve ploske višinske transformacije. Prav tako smo preverili kakovost transformacije na osnovi povprečne razlike višin reperjev in jo primerjali z rezultati transformacije, ki jo pridobimo na osnovi izdelave višinske transformacijske ploskve. Preverili smo tudi, kako se te transformacije skladajo z rezultati, ki jih dobimo s programom SiVis, ob zavedanju, da je ta transformacija namenjena zgolj višinam, določenim z GNSS višinomerstvom.

• Title: Determination of the height transformation surface in selected areas of Slovenia : graduation thesis

Abstract

In the diploma thesis we discussed the problem of transformation between the height systems SVS2000 (datum Trieste) and SVS2010 (datum Koper). The difference between the height systems throughout the entire territory of Slovenia is not constant, so we do not yet know a uniform model of transformation in Slovenia. In the diploma thesis, we determined the local height transformation surface in the area of Prekmurje. As input data for the production of the height transformation surface, we used the height differences of the benchmarks of the levelling network of Slovenia. We analysed the influence of different interpolation methods, the influence of the use of different benchmarks and the influence of the size of the determination of the surface height transformation. We also checked the quality of the transformation based on the average difference in the heights of the benchmarks and compared it with the results of the transformation obtained based on the construction of the height transformation surface. We also checked how these transformations are consistent with the results obtained with the SiVis program, with awareness that this transformation is intended only for heights determined by GNSS tehnology.
