Hello Everyone, I have looked into some aspects of OSM, mostly the rendering and some of the routing code, and I am looking for some guidance before I go further.
Background: cycling routes as provided by the City in Calgary suck, so I would like to provide cyclists here with the opportunity to design our own (including suggestions for infrastructure). This would be a two-part thing: providing users the ability to suggest routes (e.g. draw an overlay on the map, following roads and paths) and render the "current" route-map like the "cycle map" does. Ultimately, I would see tagging this information into OSM data itself, but I'm guessing the in-flux data wouldn't be appropriate...? (i.e. lots of "potential" routes proposed by users) It doesn't seem that there's a solution to draw an overlay while following roads + paths, although there does seem to be good routing code. So I would see one thing that needs to be done is to hook openlayers together with a routing server to draw routes something like how google-maps does it in "My Maps" (i.e. click a few points and the shortest route between them appears as an overlay). Have I missed something and there's already code for this? The other piece would be my own tile-server covering Calgary and serving bikemap-like rendered tiles with the currently-best routes on them. I am currently trying to see how best to make this happen, and since the "cycle map" mapnik files aren't available is the mapnik-based rendering the way to go, or would osmarender (or something else?) be better? Spreadnik, maybe? Ultimately, print-ready output would also be generated. I would be thinking along the lines of having my own (up-to-date) copy of the OSM data on a local DB which also contains the information for users' routes. Is this going to be a nightmare to sync? Should I keep users' routes separately? (Bear in mind, ultimately I would see adding "lcn_ref" sorts of tags "upstream" into OSM as this matured). There's also the issue of the underlying OSM data: sometimes users will find problems with OSM, and of course it would be best to have any such edits go live to OSM. Am I totally off-base here? Or can I just put tags directly into the OSM servers (and hence just have a local renderer if I want to change the look)?
