I’m new to OSM/Cloudmade and I’m trying to figure out if it suits the needs of an application I have to develop.
The app will be similar to this Campus Map (University of Montana) http://map.umt.edu
I have a couple of questions for you:
Vector data: my application has to register all the user interaction and store it a user profile. I need to store the objects the user is near to (e.g. all the restaurants within a certain radius from the user position). Is it possible to run such a query on CloudMade and fetch all the OSM ids and tags?
Style: is it possible to change the map style on the fly, e.g. highlight certain streets via ajax?
Thanks a lot for any hints!
