20.500.12556/RUL-140370 Primerjava popolnosti OpenStreetMap, Wikimapia in OpenTopoMap za testna območja v Sloveniji diplomska naloga št.: 214/GIG Comparison of OpenStreetMap, Wikimapia and OpenTopoMap completeness for test sites in Slovenia Graduation thesis no.: 214/GIG V diplomski nalogi je preučena kakovost podatkov treh spletnih kartografskih portalov, ki nastajajo na osnovi prostovoljnih geografskih informacij ali s tujko Volunteered Geographic Information (VGI): OpenStreetMap, Wikimapia in OpenTopoMap. Analiza je bila osredotočena na oceno popolnosti in položajne točnosti prikazanih podatkov. Izbrali smo tri tipe testnih območij znotraj Slovenije, ki prikazujejo mestna, ruralna in visokogorska območja. Za vsak tip smo določili tri testna območja: za mestna testna območja Koper, Kamnik in Kočevje, za ruralna Šmarje pri Kopru, Tunjice in Senuše, za visokogorska pa Triglav, Grintovec in Šijo. Analiza je bila opravljena s pomočjo primerjave z ortofoti Cikličnega aerofotografiranja Slovenije ter s podatki Laserskega skeniranja Slovenije, uporabljene pa so bile tudi naslednje podatkovne zbirke: kataster stavb, zbirni kataster gospodarske javne infrastrukture, eVode in topografski podatki DTM. Poudarek je bil na pregledu treh objektnih skupin: stavbe, prometna omrežja (ceste in poti) in vodovje (tekoče vode). Preverili smo, ali se kakovost podatkov razlikuje med posameznimi kartografskimi portali. Preverili smo tudi, ali je kakovost podatkov različna glede na prikazan tip površja. Končni rezultati prikazujejo, da so prisotne razlike v kakovosti pri obeh primerih. This graduation thesis analyses the data quality of three online cartographic platforms that are formed based on Volunteered Geographic Information (VGI): OpenStreetMap, Wikimapia and OpenTopoMap. The analysis focused on assessing the completeness and positional accuracy of the displayed data. Three types of test sites were chosen within Slovenia’s boundaries, representing urban, rural and high mountain areas. For each type three test sites were determined: for urban test sites Koper, Kamnik and Kočevje, for rural Šmarje pri Kopru, Tunjice and Senuše, for high mountain Triglav, Grintovec and Šija. The analysis was carried out by the means of comparison with ortophoto and lidar data, but the following sources of data were used as well: building cadastre, cadastre of public infrastructure, eVode and topographic data DTM. The focus was put on reviewing three object groups: buildings, transport networks (roads and paths) and water (rivers and streams). A closer look was given to see if the quality of the data differs between the different cartographic platforms and the different types of test sites. The final results show that there are quality differences in both instances. geodezija diplomske naloge GIG OpenStreetMap Wikimapia OpenTopoMap prostovoljni geografski podatki popolnost položajna točnost geodesy graduation thesis OpenStreetMap Wikimapia OpenTopoMap volunteered geographic information completeness positional accuracy true false false [C.
