OpenStreetMap contributor activity in the Czech Republic
Vaidiš, Martin ; Moudrý, Vítězslav (advisor) ; Komárek, Jan (referee)
Today on the internet, the amount of User generated content (UGC) is increasing as fast as never before. One of its very well usable representatives are Volunteered geographic informations (VGI), which were recently gathering a lot of interest. This applies especially on the most succesfull project based on collaborative mapping - OpenStreetMaps (OSM). Beside the brief introduction of VGI and its possibilities of use, the literature research part of this work takes a closer look at OSM, its structure and its comunity of more than two and a half millions members. The paper also presents ways to get information about the activity of contributors, which is then applied it the analytical part of the work. That is mainly focused on active users in the Czech Republic and its neighbours - Germany, Poland, Slovakia and Austria. By examining data of one year, it was found, among other facts, that the number of contributors in Czech Republic is increasing much more slowly than in the community as a whole. Also, the ratio of the most active members in Czech Republic is significantly lower than usual. The results also showed, that the number of edits made to the OSM database by an average Czech contributor is significantly greater than by others, which were inclueded in this reaserch. At the same time, the importance and potential causes of these anomalies are discussed, and finally, it is proposed how the results may be used for future research.
