Re: [Geoserver-users] Labeling Polygons

[Ricardo B. <ric...@gm...>]

Thanks Andy, I was thinking a similar approach using Filter Functions using
the centroid. It says "Returns the centroid of the geometry. Can be often
used as a label point for polygons, though there is no guarantee it will
actually lie inside the geometry"

http://docs.geoserver.org/stable/en/user/filter/function_reference.html

<http://docs.geoserver.org/stable/en/user/filter/function_reference.html>I
was hoping for a better approach.

Does anybody know why GS labels more than once the same object/feature ?


Regards
