Abstract. Large amount of research work has already been done regarding many aspects of OpenStreetMap (OSM) dataset in recent years for developed countries and major world cities. On the other hand, limited work is present in scientific literature for developing or underdeveloped ones, because of poor data coverage. In presented study it has been demonstrated how Turkey-OSM dataset has spatially evolved in an 8 year time span (2007-2015) throughout the country. It is observed that there is an east-west spatial biasedness in OSM features density across the country. Population density and literacy level are found to be the two main governing factors controlling this spatial trend. Future research paradigms may involve considering contributors involvement and commenting about dataset health.
