Hi,
What client do you use? Even if your service is not tiled the client can still
make tiled, typically 256x256 sized requests.

Edward,
I'm not using a tiled map service. So that can't be it.
How do you label your polygon based on your centerpoint? Because that would be
fine for now (at least an improvement to what I have now).
But I thought Geoserver would do that automatically. Well, maybe not the
centerpoint, but only one label per polygon. And the same for lines.
Weird thing is that the layer preview of geoserver doesn't duplicate the
labels. That's what really puzzles me...
I will look into the spacearound option (the other ones I checked out already,
but didn't help).
If I can't get a solution, I will convert my lines and polygons to points and
add these to geoserver as separate layers. And use this to label the original
data. But as far as datamanagement goes, this is not a very attractive
solution...

Bram

Onderwerp: RE: [Geoserver-users] labels are occuring more than once
Bram,
Just wondering whether you are using a tiled map service to incorporate the map
in your website? If a polygon or line crosses multiple tiles, the label is
drawn on both tiles.
Also, what's the nature of your data? In order to label polygons, I typically
determine a center point for the polygon in PostGIS that I later use to label
the polygons. In this way, there's only one point that's labeled.
For lines, check out the parameters
<VendorOption name="spaceAround">
<VendorOption name="labelAllGroup">
<VendorOption name="repeat">
to adjust the repetition of labels and avoid collisions.
Regards,
Edward

Subject: [Geoserver-users] labels are occuring more than once
Hi, I'm running into a problem I cannot solve. I want to display labels of my
features (polygons, lines and points) when zoomed in. In the documentation I
see that normally every feature will be labeled once. But when I zoom in, most
of my polygons and lines display the label more than once. The further I zoom
in, the more labels it displays (of the same polygon or line).The preview of
geoserver is doing it correctly, but when I load my features on my site it goes
wrong.What am I doing wrong? Here's my SLD code of the label, maybe there's
something in there <FeatureTypeStyle>
<Rule>
<Name>Label</Name>
<MaxScaleDenominator>10000</MaxScaleDenominator>
<TextSymbolizer>
<Label>
<PropertyName xmlns="http://www.opengis.net/ogc";>code</PropertyName>
</Label>
<LabelPlacement>
<PointPlacement>
<AnchorPoint>
<AnchorPointX>0</AnchorPointX>
<AnchorPointY>0</AnchorPointY>
</AnchorPoint>
</PointPlacement>
</LabelPlacement>
<VendorOption name="group">yes</VendorOption>
</TextSymbolizer>
</Rule>
</FeatureTypeStyle> Thanks! Bram
