Offset to symbol in WMS request

Question

Is it possible to give offset to symbol of point feature using sld in openlayers or geoserver?

Answer 1

You can use the offset function on point, line and polygon features in GeoServer to style your WMS. Below is an example of how to use the offset function with a point feature in SLD:

<PointSymbolizer>
<Geometry>
<ogc:Function name="offset">
    <ogc:PropertyName>the_geom</ogc:PropertyName>
    <ogc:Literal>100</ogc:Literal>
    <ogc:Literal>-100</ogc:Literal>
    </ogc:Function>
</Geometry>
<Graphic>
  <Mark>
    <WellKnownName>circle</WellKnownName>
    <Fill>
      <CssParameter name="fill">#FF0000</CssParameter>
    </Fill>
    <Stroke>
      <CssParameter name="stroke">#000000</CssParameter>
      <CssParameter name="stroke-width">1</CssParameter>
    </Stroke>
  </Mark>
  <Size>6</Size>
</Graphic>
</PointSymbolizer>
