OpenStreetMap (OSM) is the largest and objectively the most successful project from all attempts to open-source alternative to commercial map databases and projects of the official agencies. OSM is widely popular in Czech Republic, but the quality of this VGI (volunteered geographic information) dataset has not yet been studied. This master thesis evaluates several aspects of quantifiable characteristics of buildings in Prague. The objective was to primarily evaluate completeness, semantic accuracy and shape accuracy of building footprints. Data from OSM were compared with Digital map of Prague by Geoportal Prague, which is the official map resource covering the area of the city Prague. The data processing was done in ArcGIS by the ESRI company. The results show that OSM in Prague have high semantic accuracy and almost 100% completeness in terms of total area, but more than 50% of buildings are missing basic descriptive data. In terms of shape accuracy the footprints were identified by smaller amount of vertices than the footprints from Geoportal Prague and in some cases certain architectural details were missing.
