Hi, I'm not familiar with GeoServer - I would just connect the vector data of the country with a database where I'd store the number of participants. After that I'd let Geoserver do the job. In Mapserver you can create rule based styles - so if the number of participants greater than zero display the shape green an label it - otherwise don't.
I hope there is a way in GeoServer. Thomas _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
