[Geoserver-users] question placing labels

GeoServer GeoServer User

I would like at the start of a polygon to insert a label, and at the end of
the polygon. how can I fix this in geoserver. up to now the geoserver places
it on any position above or below the polygon. by the way the labels are
different and they must be in the direction of the polygon.

Hi Ouke,

If I understand your question correctly, you would like to add a label to the start and end of the line that bounds a polygon. There is a geometric filter function to extract the start and end points of a line, e.g.:

the_geom

More info to be found here:

http://docs.geoserver.org/latest/en/user/styling/sld-extensions/geometry-transformations.html#start-and-end-point

Also, you indicated that the label should follow the direction of this line. For this, another geometric filter function is required, e.g.

<PointPlacement>
…
<Rotation>
<ogc:Function name=“startAngle”>
ogc:PropertyNamethe_geom</ogc:PropertyName>
</ogc:Function>
</Rotation>
</PointPlacement>

Hope that helps

Kind regards,

Edward
