Yes, I know that site - it's good for debugging OSM data but not really a site I would recommend to a non-techie who just wants to know how to get from A to B. That is the great strength of Öpnvkarte. *Sébastien Aubry* wrote:
There are two ways to proceed: - like you said, this could be added to the default OSM map as a layer. To ask for such a feature, we should create a ticket on the OSM trac: http://trac.openstreetmap.org , perhaps on the mapnik component ?
You're right, I should have thought of that :-)
- we could provide Transiki with these ideas. This default, simple map could be the first step of this initiative, allowing us to move further by inputting the schedules in the next steps.
Not a bad idea - in fact, I have only heard of Transiki but not looked at it in detail, but I guess this is something they might be interested in. Though Transiki would be primarily a user, but maybe joining forces helps us get more people who are interested, willing to contribute ideas and work and so on...
We could also ask the creators of openbusmap if they would agree to open their code.
Yes, I thought of that, too. I'll get in touch with Melchior to see if he's willing to share the work he's already done. *Sander Deryckere wrote: *> >/ Step 1: Add the new map view /> >/

I was generalizing: Mapnik, to my knowledge, renders tiles only when they are viewed and either "dirty" (changed since they were last rendered) or more than a week old. So the rendering effort for the current Mapnik style would remain roughly the same, but there would be extra effort to render the new style (if it gets viewed). If someone switches from one view to another, this may result in the viewing area being rendered twice, and finally I have made the bold assumption that a public transport map would get us some more traffic. In fact, our mileage may (and probably will) vary. As for rendering both styles together: that's a performance and tuning issue we might want to look at...

I believe most power users don't use a ie browser. So if they are not power users, the extra clicks to download and view it are small. So converting it is not really needed.
True for power users, but I'm envisioning a "grandmother-proof" solution (i.e. a website that even your grandmother will be able to use without problems). Thanks to all of you for your input so far. Further ideas are always welcome, of course. I'm thinking of setting up a Wiki page (along with a ticket) as a central "brain" for these efforts and will keep you up to date.
