Oh, right, I missed that. If only someone wrote an open source TYP file generator that processes text files. I still do have the plan to write something in Perl or GNU Assembler. >Therefore, I would suggest that you think about distributing your TYP >file, potentially with the style files, but note that users will have >to adjust the name and IDs when they generate their own maps. Preferrably I would distribute just the source files (a Perl script or GNU assembler input, and the script to drive the translation). For now, I plan to distribute the TYP file, outside mkgmap. Even the "routes" style is somewhat useable without a TYP file. It is merely confusing to look at the map when the public transportation routes are displayed as boundaries on top of a map that already has administrative boundaries between suburbs. >(And by the way, thanks for taking the initiative on this. Last year I >created a test public transportation layer, but have not had time to >document or distribute what I did.) No problem, I find public transportation second best to human-powered transportation (walking&bicycling), and want to serve this important audience too. I am open to any suggestions you might have, such as differentiating different modes of rail transportation. Currently trams, railway, subway are shown in the same line style, and subway routes are shown even where they are underground. The POIs for the stops are in the default style, because I think that someone who knows the city doesn't need the "routes" layer most of the time, but will still find it useful to search for stops. I think that the "routes" layer should only show lines. One problem with route relations is a limitation of the current "apply" command in the relations style file. It would be nice to apply the relations in a sorted order (by ref or name) and to filter out duplicates. If you have a bus route split in two relations (one per direction), you will see the bus line ref twice on ways that are used in both route directions. Likewise for stops that are used for both route directions (the start and end stops, at least). I posted a patch as the base of discussion some time ago, but nobody replied. This is not just about bus or train routes, but about any route relations. Best regards, Marko
