Hi Hanno, If you are storing your data in a PostGIS database, you can extract your data in an openlayers friendly format (KML, GML, GeoJSON) using a SELECT ST_AsKML query. See http://postgis.refractions.net/docs/ST_AsKML.html http://postgis.refractions.net/docs/ST_AsKML.html You could also wr

If you have so many shapes you could: 1) Reduce the number of shapes to like 100 2) Render your layer server-side and serve it via WMS-C for example Depends what are you using your vector layer for, as a workground you can: on small scales use the "WMS layer" of your data and on big scales use the
