I am interested in mapping the London congestion charging zone but there seems to be no formal tag for it. I can deduce from the OSM Inspector that "cc" is unusually short and therefore should be ignored, but what I hope to do at some point is tag affected roads with a key like "congestioncharge=yes" to imply the standard values like "fee=10" and "toll:motorcar=yes" and that would render on Mapnik as a zone with a red border, but what is unique is that it is £10 a day, not £10 a go. How do I get around to do this properly and what is the best way to do this because I am hoping that OSM could help drivers avoid the charge zone, with the number of drivers using OSM increasing. Thanks! |
