Hi Hinnack Create a vector polygon layer where each seat is a small polygon. Use a metric cartesian coordinate system. You just get the user to zoom in and select the seat. The vector layer could either be loaded into memory from a GeoJSON file on the server, or could be served as WMS, so you use GetFeatureInfo requests to return the seat the user clicks on.

So I wonder, if a "pixel-based projection" exists - and if not, how to start one. The booking engine of a ticket system has the same needs, as a map has (e.g. overlays like Images, kml's, zooming, etc.). Of course, one could reinvent the wheel by using other js libs like "Raphael" - but it does not to make much sense to me... Did I overlook something and it does already exists?
