This thesis focuses on the issue of Linked Open Data projects Wikidata and DBpedia, with the main aim on spatial data. The objective of this work is to find a way, how it is possible to use spatial data from these projects and how to visualise them. The content of this work is detailed comparison of structure, accessibility, description of spatial features and extensiveness of both database projects. The thesis further explains the specificities connected with spatial data in those databases and offers an example, how to use the data in a cartographic application. In the example application are present two queries in the SPARQL language, which one allows to find and display a) cities with female mayor and b) birthplaces of Nobel prize laureates, in the map window. The code of this application is open source, hence anyone can get inspired and adapt the application for one’s purpose.
