A Semantic Region Growing Algorithm: Extraction of Urban Settings 23 The thematic or semantic aspect of spatial features is managed through a tagging system where each geometric feature is described by an arbitrary number of tags. As the OpenStreetMap project evolved and prospered over time, its community developed a set of tagging guidelines that describe which tags should be used for a specific feature. Before contributing new information to the database, mappers are asked to carefully read these guidelines.

Therefore, we collected data from Metro Extracts,2 a website that provides parts of the OSM datasets for cities and their surroundings. com/.
