Abstract

GIS orodja so v dobi informatike postala eno od osnovnih orodij, ki jih uporabljamo na Geološkem zavodu Slovenije. Najbolj znano med njimi je orodje ArcGIS. Zaradi visoke cene orodja pa razpolagamo z manjšim številom licenc od povpraševanja uporabnikov, zato smo že pred leti predlagali prehod na rabo prostega in odprtokodnega orodja QGIS. Ker se v tem času potrebe po licencah ArcGIS še naprej povečujejo, nadaljnji način licenciranja pa postaja nejasen, smo raziskali, kakšne so možnosti prehoda na QGIS. Raziskave smo se lotili z metodologijo študije primera. Podatke smo zbirali kot aktivni opazovalci, z anketo, intervjuji ter zunanjimi viri. Pri tem smo iskali odgovor na dve vprašanji: v kolikšni meri je QGIS primerno nadomestilo za orodje ArcGIS ter kako novo orodje vpeljati v uporabo. QGIS se je izkazal kot povsem uporabno orodje pri manj do srednje zahtevnih opravilih, ki pri delu Geološkega zavoda Slovenije predstavljajo večino; na podlagi tega bi bilo mogoče sklepati, da bi to orodje lahko v veliki meri nadomestilo ArcGIS. Pri zahtevnejših opravilih pa QGIS še ne dosega ArcGIS, a tudi na teh področjih razvojno napreduje. Prav zato bi bilo mogoče povzeti, da je za potrebe Geološkega zavoda najprimernejša sočasna uporaba obeh programov: ArcGIS za zahtevno uporabo in QGIS za preostala opravila. Pri prehodu na uporabo orodja QGIS smo se soočili z odporom do novega programa, zato smo nove uporabnike skušali motivirati s tečajem in dostopom do dodatnih informacij in pomoči. S tečajem QGIS smo zaposlenim približali prednosti orodja QGIS, jim predstavili njegove zmogljivosti ter razbili morebitne predsodke in nelagodje pred neznanim orodjem. Poleg tega smo z namenskim kanalom za uporabnike QGIS prek platforme Teams poskrbeli za pomoč ob morebitnih težavah in vprašanjih ter jim omogočili dodaten vir informacij. Tečaj je bil zelo dobro sprejet in prvi vtisi so spodbudni, seveda pa bo rezultate mogoče tehtno oceniti šele po daljšem časovnem obdobju. Kanal za uporabnike QGIS je trenutno še slabo obiskan, vendar pričakujemo, da se bo to ob pogostejši uporabi orodja QGIS spremenilo.

Secondary title:	A study of the possibilities for migrating from ArcGIS to open source QGIS
Secondary abstract:	In the era of informatics, GIS tools are fundamental tools used at the Geological Survey of Slovenia. The most popular among them is ArcGIS. However, due to high prices of ArcGIS licences the number of licences we can afford is lower than the number of potential users. Therefore, a few years ago we proposed the migration to free and open code tool QGIS. As there is a pressing need for more licences among our users and the future of licencing is unclear, we conducted a research on the possibilities for migration to QGIS. In our research we used case study methodology. We gathered data as active observers, through questionnaires, interviews as well as from outer sources. We tried to find the answers to two questions: to which extent QGIS is a suitable replacement for ArcGIS and how to introduce this new tool into practice. We found QGIS to be a suitable tool in tasks of low to medium complexity, which are most of the tasks performed at the Geological Survey of Slovenia. On this basis it can be concluded that this tool can to a large extent replace ArcGIS. In tasks of high complexity QGIS cannot reach the performance of ArcGIS. However, it is rapidly developing also in this field. It can therefore be concluded that for the needs of the Geological Survey of Slovenia, the most appropriate appears to be the combined use of both tools: ArcGIS for solving complex tasks and QGIS for other tasks. During the introduction of QGIS we also encountered the resistance of our users against the new programme, which we tried to overcome with a training course and additional information and support. Through the QGIS training course we presented to our users the advantages and capacities of the QGIS tool and dispelled their prejudices and insecurities against unknown tools. Moreover, we opened a special channel for immediate support using MS Teams platform for resolving possible difficulties and questions and as an additional information source. The course was well accepted, and the first impressions are encouraging. However, the results can be properly evaluated only after a certain period of time. The channel for QGIS users currently does not have many visitors, but we expect the number of visitors to increase with more frequent use of QGIS.
