Hello everybody, the code is public available as part of the Overpass API repository and has always been. A pointer to the main file is: https://github.com/drolbr/Overpass-API/blob/minor_issues/src/pt_diagrams/topographic.cc
I'm sorry for the confusion. "not publicly announced" shall mean that there is no documentation because the code never got production ready. Line separation works, colour selection works good enough, label placement doesn't work and is a hard problem. This includes line numbers. I'm happy to answer questions to get that code to productive use. Best regards, Roland _______________________________________________ Talk-transit mailing list Talk-transit@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-transit
