Hello Tim, thank you for the answer! I looked into solution (1) and it seemed to be too complicated and needs cgi-script installation on the server, also configuration for each layer to make it work. Actually "gutter" is probably what I need - but there is almost nothing on google about gutter/openlayers... :( This is my test application: http://map.webser125.lookass.ch/openlayers/ex_rpag_google.php I used "gutter: 200" on it, but nothing changed / happened. Applying any gutter doesn't change anything. What am I missing? (btw: looking at this WMS in a Desktiop GIS like UDIG works fine, all descriptions are totally visible...)

When you you request a tile from MapServer with bounds that contain your train station (point), MapServer will render as much of that symbol as it can on that tile. When you request the next tile that doesn't contain the train station (point), MapServer has no reason to render a partial train station. You can get around this in two ways: 1) use something that requests larger tiles with a buffer, slices them up in to smaller tiles and discards the buffer - see http://tilecache.org or 2) use the "gutter" property on your WMS layer in OpenLayers - see http://dev.openlayers.org/docs/files/OpenLayers/Layer-js.html#OpenLayers.Layer.gutter # ignore a 10 pixel gutter around each tile var layer = new OpenLayers.Layer.WMS(name, url, params, {gutter: 10}); Good luck, Tim _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
