Hello, I play a little bit around with bbox- and cluster-strategy in Openlayers. So it updates dynamically the data's for the actual viewpoint of the user.
Here is the example with Wikipedia coordinates without clustering: http://toolserver.org/~kolossos/qtm2/queryinmap-bbox.php and here with clustering (look's funny): http://toolserver.org/~kolossos/qtm2/query-in-bbox2.php
What not works are the popups. JavaScript doesn't love me and there seems to be a different between Vector- and GML-Layers in OpenLayers. Is there somebody here who could repair the popups?
I would like to move with wikipedia coordinates and your Commons:Geocoding image layer to opensource software. For Query-to-map could a bbox strategy the kill for the database server.
