Tag the way as some like highway= 'racing_line'. I looked at the image of it in nearmap & you can clearly see that defined in rubber. This would cause a problem if width=* was added & the render used it, but would be avoidable if the ways & mp's were related as you suggested. Creating a new tag is not a problem, especially if it's solving a problem that hasn't yet been solved. If you were into mapping race tracks & depending on how detailed you want to go, you could add tags like speed, gear & G force to the appropriate points on that way & produce a track guide. > >>> I think it would be prudent to explicitly state this relationship >>> between the way (giving centerline) and the MP (giving area)...with a >>> relation.

I'm going to have to have a think about this... Cheers Dave F. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
