Hi Jan,
Aha. Well, I guess I should have ready the mail a bit more closely. 
You may want to try something like this..
Define a view in PostGIS and register it with Geoserver, something like this...
SELECT ST_PointOnSurface(the_geom) ....(rest of your columns here)...
FROM mygeometrytable
You probably would want to dump this into a table to speed up
everything, as you do not want to have to calculate this everytime you
hit the layer.
This function (unlike the centroid function) is supposed to provide a
point on or inside the surface. It has worked for me, but your mileage
may vary.
You can seen an example of this here..
Centroids
http://www.who.int/tools/geoserver/wms/kml_reflect?layers=WHO:countries_centroid
PointOnSurface
http://www.who.int/tools/geoserver/wms/kml_reflect?layers=WHO:countries_inside_points
If you look at Malaysia, the geometry returned from PointOnSurface is
actually in Western Malaysia. The centroid is out in the sea.
If you use FME, there is a function "InsidePointExtractor" that will
do the same thing and you can dump the results into another table for
performance.
Maybe this is more of what you are looking for?
Regards,
Jason

Onderwerp: Re: [Geoserver-users] labeling polygonsHi Jan,
You will need to develop SLD's and freemarker templates to control the
KML output.I refer you to http://geoserver.org/display/GEOSDOC/KML+Placemark+Templates.
Groetjes,

Hi All,
can anybody help me?
I'm using Geoserver in combination with Google Earth.
The problem I met is labeling polygons.
I think/suspect the label position is calculated by the boundary box coordinates of the polygon.
So e.g. with curved polygons or polygons with a holes in it, labels are placed outside the polygon.Are there options in SLD to ensure that each label is placed inside the polygon?
Thanks,
Jan
