I developed a tool to import OpenStreetMap (OSM) data into Transport Fever 2. This approach can accelerate the reconstruction/replication of real world places in the game. Currently, the tool can automatically build streets, tracks, forests, town labels, railway signals, and some point objects. Before applying OSM-Importer you need a prepared map with an overlay for the OSM map and a heightmap for the terrain.
