Again: The lines on the map of the city of Utrecht are not routes at all. They are roughly the ways busiest with cyclist radiating out of the central railway station. Even for it's purpose it is fairly useless, since it misses all the important tangential routes. There are similar maps made by the city of Utrecht for car traffic. As usual the holy cow of western society (the car) gets more attention and these maps have move detail (like traffic in tangential directions and neighbourhood feeders). The local mappers used these as a rough guideline for which roads to map as primary, secondary and tertiary. That is the normal flow of information. You can use the (overly) generalized maps made for policy making to selectively add information to OSM, but making these style of maps always requires human editors of the map (not just of the map data). --- m.v.g., Cartinus ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] OSM cycle map - ?excessive focus on long-distance routes
My point is that tagging should allow both types of routes to be recorded, so different renderings can be produced for different purposes (and indeed routers can use the information as well, if they want to). I know that different route networks apply for different purposes in my city (and have tagged and rendered accordingly); I just thought it interesting to note that that difference was also regarded as obvious in a major Dutch city.

I think the lines on [1] are merely a guideline for cyclists what the recommended route from the suburbs to the city center is. If they are signposted then only by official roadsigns (like these here [2]) but these are not cycleroutes, just as destinations for cars on roadsigns are not carroutes. On the OCM there are different things highlighted. - in blue dashed lines: cycleways (highway=cycleway) - in red (solid on zoom = 12, opaque on zoom 12): national (leisure) cycleroutes - in light blue: regional cycleroutes - in dark blue: local cycleroutes These are described on [3] and have specific signposts showing the route and intermediate points.

Re: [OSM-talk] OSM cycle map - ?excessive focus on long-distance routes
You'd have to ask the City of Utrecht whether their main cycle routes are signed. If they've officially identified a particular set of routes, that would seem to be fairly clear-cut.

Well, ok, I wasn't really asking what I'd have to ask, more what your point is. :) If the routes are signed, that's good. If there are measurements that can be tagged in OSM (vehicles per hour, or surface quality, or whatever), that's good too. Anything objective can be tagged, and rendered by a Maperitive guru such as yourself. openwoollymammothmap.org is still there for the taking.
