Abstract

V magistrski nalogi smo primerjali kakovost in ekonomičnost izdelave ortofotov, izdelanih z različnimi postopki obdelave. Na dveh študijskih območjih v Mestni občini Ljubljana smo izdelali smo po tri ortofote in sicer en klasični ter dva popolna ortofota. Za izdelavo smo uporabili različna programska orodja z različno stopnjo avtomatizacije. Posebej so nas zanimali rezultati avtomatske obdelave podatkov za namen izdelave popolnega ortofota s programskim orodjem SURE. Na končnih izdelkih smo medsebojno primerjali semantično kakovost in vsesplošen estetski videz. Ocenili smo relativno položajno točnost posameznega izdelka in izvedli vizualno primerjavo geometrične kakovosti. Ker se postopki obdelave glede na izbrano programsko orodje razlikujejo, smo medsebojno primerjali tudi kompleksnost postopkov in čas ročne obdelave podatkov ter s tem povezane stroške obdelave. Nazadnje smo za primer izdelave popolnega ortofota z uporabo programskega orodja SURE izdelali še SWOT analizo.

Secondary title: Quality and cost-efficiency assessment of classical and true orthophoto
Secondary abstract: In this master's thesis, we analized the quality of orthophotos made with different processing procedures and cost-efficiency of their production. We made three orthophotos for each of the two study areas in the City of Ljubljana, i.e. one classical orthophoto and two true orthophotos. Different software was used for their production, which support different levels of data processing automation. We were especially interested in the results of automatic data processing to create a true orthophoto with the SURE software. We compared the semantic quality and the overall aesthetic appearance of all produced orthophotos. We also assessed the relative positional accuracy of each product and performed a visual comparison of geometric quality. Because the processing procedures differ depending on the selected software, we also compared the complexity of the procedures and the time needed for manual data processing, as well as the related processing costs. Finally, we made a SWOT analysis for the case of automatic data processing using the SURE software tool.In this master's thesis, we analized the quality of orthophotos made with different processing procedures and cost-efficiency of their production.
