Impromptu interviews with a variety of attendees during the SotM 2026 event
OpenStreetMap centerlines carry enough topological, geometric and semantic information to reconstruct lane-level road networks — if interpreted correctly. This study proposes treating OSM centerlines as structural representations of dominant traffic flow rather than geometric midlines, and reconstructs detailed lane networks and 2D areal road geometries through a hierarchical, connectivity-driven process guided by topology, geometry, and OSM tag semantics. Applied to Delft, the Netherlands, the framework produces a complete, functionally typed lane-level network and seamless areal road representations covering diverse urban road configurations, validated against satellite imagery.
CartAGen is an open source Python library that highly facilitates the use of map generalisation algorithms. This new tool could change how basemap producers that rely on OSM data design their maps.
