[OSM-dev] Trial clickable POI layer

I've played with OL today and with some help from crschmidt I got the
following working:


It displays a mapnik map, with POIs over the top. Now, they basic
functionality, but:

1. There's a lot of POIs in some areas. It maxes out a displaying 100,
but we probably need to come up with a better algorithm.
2. The icons suck, but they're only ones I could find quickly. I'm
thinking of extracting the icons from Osmarender.
3. Only a few tag types are supported, basically the ones I could find
images for. Actually, I suppose the POI rules could be copied from
osmarender too...
4. The popups suck rocks too. Anybody know a site with OL popups that
don't suck?

One direction is see for this is a public transport layer, displaying
bus stops and stuff, but I couldn't find any suitable images for
anything other than trains.

I think this method is better than the POIs on the tiles, since here
we can make them selectable (choose which things to see).

Anyway, if people like it I'll move it to dev, so it'll be much
snappier. Just after I work out how to create a postgres db there...

Have a nice day,
