OpenStreetMap
I am jsut wondering whether trhere is a way of mapping elemenst only for certain groups of users.
For example, there may be areas that may only be passed by certain groups who are allowed there by their job or something.
It would be good to have a way of sort of "categorizing" map objects, for example there could be a field "limited_to" that the ncould contain something like "oxford_students".
When downloading maps, these areas could be enabled or disabled in some way.
Any ideas about that?
Regards,
Nik

The normal method would probably be a form of the access tag

While the online map viewers only have a few limited categories – like OpenCycleMap for bicyclists – the offline map editors are able to show and hide different layers, if I’m not mistaken.

Map the restriction in a sensible way (e.g. access=oxford_students) and then it is up to you to (find a coder to)create a map using the OSM data showing.hiding what tags you want.
Most of the maps (mapnik, osmarender, cycle map, etc) will mark roads with a red hash if they have any value for the 'access' tag. It would make sense for any router to ignore any roads with the access tag, unless it accepts a specific value for it (e.g. access=emergency when in emergency vehicle mode).
I'm working towards creating a university-focused map render. I haven't mapped anything as being access to students only, but expect this to become clear when the boundary around colleges is shown up.
