[MS4W-Users] Rotate symbols using SLD and database field

[Srilakshmi Kandala]

Hi,
 
I am working with ms4w_3.0_beta11 and OpenLayers to render maps. The data for the map, exists in PostGIS database. I am trying to apply rotation to symbols using SLD, but it does not seem to work. A part of the mapfile i am using is as follows:
 
Symbol
Name 'iftriangle'
Type VECTOR
Filled TRUE
Points
0 0
.5 2
1 0
0 0
END
END 
 
LAYER
        NAME 'Sectors_GSM'
        TYPE point       
        CONNECTIONTYPE POSTGIS
        CONNECTION 'host=localhost user=postgres port=5432 dbname=dbname password=pwd'
        DATA 'wkb_geometry from tablename USING UNIQUE ogc_fid using SRID=900914'     
        METADATA
            'wms_title' 'Sectors'
        END  
                              
        STATUS ON
        TRANSPARENCY 100
        PROJECTION
            "init=EPSG:900913"
        END
        
        CLASSITEM 'antenna_type'
        CLASS
            NAME 'GSM'    
            STYLE
               SYMBOL 'iftriangle'
               SIZE 15
               COLOR 51 51 204
               ANGLE [orientation]
         END
        END
  END         
  
 
This layer renders correctly. But when i try to apply a filter using SLD, the map renders, but the symbols are not rotated. Here is the SLD file i am using:

 

<StyledLayerDescriptor version="1.1.0" xmlns="http://www.opengis.net/sld" xmlns:se="http://www.opengis.net/se" 

xmlns:ogc="http://www.opengis.net/ogc" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xsi:schemaLocation="http://www.opengis.net/sld http://schemas.opengis.net/sld/1.1.0/StyledLayerDescriptor.xsd">
  <NamedLayer>
    <se:Name>Sectors</se:Name>
    <UserStyle>
      <se:FeatureTypeStyle>
        <se:Rule>
          <se:Name>M</se:Name>
          <ogc:Filter>
            <ogc:PropertyIsEqualTo>
              <ogc:PropertyName>antenna_type</ogc:PropertyName>
              <ogc:Literal>M</ogc:Literal>
            </ogc:PropertyIsEqualTo>
          </ogc:Filter>
          <se:PointSymbolizer>
            <se:Graphic>
              <se:Mark>
                <se:WellKnownName>iftriangle</se:WellKnownName>
                <se:Fill>
                  <se:CssParameter name="fill">#660033</se:CssParameter>
                </se:Fill>
              </se:Mark>
              <se:Size>15</se:Size>
              <se:Rotation>                
                  <ogc:PropertyName>orientation</ogc:PropertyName>                
              </se:Rotation>
            </se:Graphic>
          </se:PointSymbolizer>
        </se:Rule>
      </se:FeatureTypeStyle>
    </UserStyle>
  </NamedLayer>
</StyledLayerDescriptor>

 

I have also tried the above with SLD version 1.0.0. Nothing seems to work. But if i give 
 <se:Rotation>45</se:Rotation>, it works. The symbols are rotated by 45 degrees.

 

I need to get that angle from PostGIS database. Please help me.

 

Thank you, 
Srilakshmi
