20.500.12556/RUL-162774 Ocena kakovosti podatkov OpenStreetMap v skladu s standardom ISO 19157-1:2023 magistrsko delo OpenStreetMap data quality assessment according to the ISO 19157- 1:2023 master thesis Kakovost podatkov je eden izmed ključnih dejavnikov, ki je odločilen pri izbiri nabora podatkov za določeno uporabo. OpenStreetMap (OSM) je najbolj razbirjena in najbolj popolna podatkovna baza prostovoljno zbranih prostorskih podatkov (VGI). Njihova kakovost je zelo heterogena in odvisna od mnogih dejavnikov. Ocena kakovosti mora biti objektivna, zato smo kakovost podatkov OpenStreetMap ocenili po elementih kakovosti in v skladu s postopki, kot jih predpisuje novi standard ISO 19157- 1:2023. Analizirali smo tri tipe testnih območij v Bosni in Hercegovini ter Sloveniji, ki prikazujejo mestna, ruralna in visokogorska območja. Za vsak tip testnega območja smo analizirali po dva primera za vsako državo. Analiza je bila usmerjena na oceno kakovosti naslednjih objektnih skupin: stavb, prometnih omrežij in vegetacije. Pri tem smo se osredotočili na preučevanje tako linijskih kot tudi ploskovnih elementov, katerih analiza nam je predstavljala večji izziv. Preverili smo, ali je kakovost podatkov odvisna od tipa območja ter ali se kakovost podatkov med dvema obravnavanima državama razlikuje. Rezultati so pokazali različno stopnjo kakovosti med različnimi vrstami testnih območjih. Na podlagi analize smo ugotovili, da se kakovost podatkov razlikuje glede na tip testnega območja, tako za območja v Bosni in Hercegovini, kot tudi za območja v Sloveniji, be večje razlike smo opazili pri primerjavi istega tipa testnega območja v dveh analiziranih državah. Raziskava je pokazala, da se doseženi rezultati deloma skladajo z drugimi podobnimi izvedenimi btudijami. Ključno ugotovljeno dejstvo pa je, da je kakovost podatkov v OpenStreetMap precej odvisna od angažiranosti prostovoljcev na določenem območju, bele nato od tipa testnega območja. Data quality is one of the key factors that determine the choice of dataset for particular purpose. OpenStreetMap (OSM) is the most widely used and most complete database of volunteered geographic information (VGI). Its quality is very heterogenous and depends on many factors. The quality assessment must be objective; therefore, we have assessed the quality of OpenStreetMap data according to the quality elements and according to the procedures described by standard ISO 19157-2:2023. We analysed three types of test areas in Bosnia and Herzegovina and Slovenija, representing urban, rural and high mountain areas. For each type of test area, we analysed two sites in both countries. The analysis focused on assessing the quality of the following groups of objects: buildings, transport networks and vegetation. The focus was on both linear and planar elements, which were more difficult and challenging to analyse. We tested whether the quality of the data depends on the type of area and whether it differs between the two countries. The results showed different levels of quality between the different types of test areas. Based on the analysis, we found that the quality of data varies according to the type of test area, both for areas in Bosnia and Herzegovina and for areas in Slovenia, with even greater differences observed when comparing the same type of test area in the two countries analysed. The study showed that the results obtained are partly consistent with other similar studies. However, the key finding is that the quality of the data in OpenStreetMap depends a lot on the involvement of volunteers in a given area, and only then on the type of test area. magistrska dela geodezija ocena kakovosti elementi kakovosti stavbe prometna omrežja vegetacija OpenStreetMap prostovoljne geografske informacije ISO 19157-1:2023 master thesis geodesy quality assessment quality elements buildings transport networks vegetation volunteered geographic information true false false [A.
