Does open data open new horizons in urban planning?

Abstract. This study deals with the issue of the availability of open data in the Czech Republic and their extent to which they are used in the framework of urban planning and development of urban space. In the context of rapid digitization and technological progress, open data is becoming increasingly important for the effective management and design of urban infrastructure. This work systematically analyses the current state of open data in Czech regional capitals, identifies key aspects of their availability and examines their potential applications in urban planning. In the practical part, the study focuses in more detail on Brno, which is the second largest city in the Czech Republic and provides freely available data on its website data.brno.cz.
