Hi Steve, maybe you can help me with that? I seem to have no img file with an example. I guess we have to 1) add a flag to RouteNode which says whether or not the node is used for routing. A RouteNode for housenumbers will have arcs like a normal one, but they are only used to allow placing the housenumber infos. 2) change RoadDef.writeNod2() to create the bitstream using this flag. 3) What happens with the complex routing routines in RouteNode, e.g. addArcsToMajorRoads() ? Do we have to add arcs to the "housenumber nodes" ? 4) In StyledConverter I see a call road.setStartsWithNode(nodeIndices.get(0) == 0); which seems to always set the bit to true. The code in RoadHelper may be work different. Do you have an example that explains this? Attached patch shows how I intend to implement the random housenumbers, it doesn't do anything useful yet. Maybe you can tell me if I am on the right way?
