Hi Robert,
It's all about the meta-tiling, i.e. what's the size of the image being
requested by GWC to your GeoServer instance? That's something to configure in
GWC I presume.

Edward

Hi,
Sorry for being thick, but the tiles are infact being cached...hence the url
"geoserver/gwc/service/wms" in the wms path
var layer_ortsnamen_lk = new
OpenLayers.Layer.WMS("Ortsnamen","http://maps.zgb.de/geoserver/gwc/service/wms";,
{ layers: 'zgb:ortsnamen_lk',
projection: "EPSG:900913", format: 'image/png', transparent:
true }, { 'buffer': 0, 'opacity': 1, 'isBaseLayer':
false, visibility: true, singleTile: true });
Yours,
Rob

Betreff: RE: [Geoserver-users] missing label???
Robert,
The OpenLayers preview requests the settlement names as one image, while the
application is requesting several tiles to compose the map. It appears your
tiling scheme coincides with the location of the town of Gifhorn. There's been
a previous thread covering the case of "London" or "Greenwich". As it is
located at the cut of the tiles, the names never appear on the map!
That's where meta tiling comes in. Since town names don't change that often,
it's a likely target for creating a tile cache! The tiling engine (e.g.
MapCache, MapProxy, TileCache, GeoWebCache...) requests a larger image (meta
tile) of 1280x1280 and slices this one into 25 tiles of 256x256. As the meta
tile is larger in size, there is more chance the label is put on the map.
Regards,
Edward

Subject: [Geoserver-users] missing label???
Hi,
I have a point geometry which has a label defined in an SLD file as ...
in the application the most northen label "Gifhorn" is never shown
http://maps.zgb.de/ertragspotenzial/
but in the geoserver preview it is shown
http://maps.zgb.de/geoserver/zgb/wms?service=WMS&version=1.1.0&request=GetMap&layers=zgb:ortsnamen_lk&styles=&bbox=3577932.527,5754071.798,3637335.239,5816477.606&width=487&height=512&srs=EPSG:31467&format=application/openlayers
What is preventing the label from being displayed? I have of course tried
various combination before writing, but to no avail.
yours,
Rob
