[Geoserver-users] Different Labels using filter SLD

Hahesa · August 29, 2017, 12:07am

Hello everyone
I have a question! I have a rule for different classes of roads, and I need
labeling that classes with differents label rules. The routes under number
10 with a background shield , and routes above number 11 another shield.
I have this code:

<sld:TextSymbolizer>
            <sld:Label>
              <ogc:PropertyName>NumRuta</ogc:PropertyName>* ## I need filter
here?#*#
            </sld:Label>
            <sld:Font>
              <sld:CssParameter name="font-family">News Gothic
Bold</sld:CssParameter>
              <sld:CssParameter name="font-size">11</sld:CssParameter>
              <sld:CssParameter name="font-style">bold</sld:CssParameter>
              <sld:CssParameter name="font-weight">normal</sld:CssParameter>
            </sld:Font>
            <sld:LabelPlacement>
              <sld:PointPlacement>
               <Rotation>0</Rotation>
              </sld:PointPlacement>
            </sld:LabelPlacement>
            <sld:Fill>
              <sld:CssParameter name="fill">#323232</sld:CssParameter>
            </sld:Fill>
                  <sld:Graphic>
                    <sld:ExternalGraphic> <sld:OnlineResource
xlink:type="simple" xlink:href="background_security2.svg"
/><Format>image/svg+xml</Format>
                    </sld:ExternalGraphic>
                    <sld:Size>20</sld:Size>
                  </sld:Graphic>
            <VendorOption name="followLine">false</VendorOption>
            <VendorOption name="graphic-resize">proportional</VendorOption>
            <VendorOption name="graphic-margin">3</VendorOption>
            <VendorOption name="repeat">100</VendorOption>
            <VendorOption name="labelAllGroup">true</VendorOption>
          </sld:TextSymbolizer>

Hi Hanesa,

Yes, you need filter:

<ogc:Filter>
         <ogc:PropertyIsEqualTo>
           <ogc:PropertyName>..</ogc:PropertyName>
           <ogc:Literal></ogc:Literal>
         </ogc:PropertyIsEqualTo>
       </ogc:Filter>

You can find some examples here:

Hello everyone
I have a question! I have a rule for different classes of roads,

ogc:Filter usually goes straight into a Rule. If you have diferent
rules for different road classes, then you can add your label
symbolizers to the respective rules instead of creating a genereal
label-rule.

All the best,
Tõnis

Hi,

An ogc:Filter goes into the Rule tag (as is partly visible on your screenshot aswell), but you can try this as your label tag:

NumRuta 10 NumRuta This get's rendered as a lable if NumRuta >= 10

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

btw a superhandy SLD cheat-sheet ftp://download.osgeo.org/osgeo/foss4g/2009/SPREP/1Wed/Parkside%20GO3/1300/SLDReferenceSheet.pdf

All the best,
Tõnis

No, as Tõnis says you need to use the filter in the rule not the label.
