Native Kotlin plugin for editing Lanelet2 maps in JOSM — lanelets, regulatory elements, routing debug, and a live 3D viewer.
The Lanelet2 JOSM plugin adds map-editing tools to JOSM as a native Kotlin plugin (lanelet2.jar). Create and merge lanelets, tag regulatory elements, inspect the routing graph, and preview the map in 3D.
Most tools are self-contained. A few actions also use a local Python lanelet2 install. Ad-hoc Python scripts against JOSM objects are handled by the companion GraalPy plugin.
