From a wms service I know its url and a layer name called: CATAST_Pol_Municipio

https://idena.navarra.es/ogc/wms

I need to apply a cql_filter on a GetMap request on that layer, filtering by national cadastral reference. Tried cql_filter=nationalCadastralReference=xxxxxxxx but it says that there is no property with nationalCadastralReference name.

Rendering process failed PropertyDescriptor is null - did you request a property that does not exist?

How can I know the wms properties that I can filter the request with?

There are two possible solutions to this:

  1. Ask the related WFS for a description of the featureType using https://idena.navarra.es/ogc/wfs?request=DescribeFeatureType&typeName=CATAST_Pol_Municipio&version=1.1.0 which returns:

     <xsd:complexContent>                                                        
       <xsd:extension base="gml:AbstractFeatureType">                            
         <xsd:sequence>                                                          
           <xsd:element maxOccurs="1" minOccurs="0" name="the_geom" nillable="true" type="gml:MultiSurfacePropertyType"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="FEATURE" nillable="true" type="xsd:int"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="CMUNICIPIO" nillable="true" type="xsd:long"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="MUNICIPIO" nillable="true" type="xsd:string"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="MUNINOAC" nillable="true" type="xsd:string"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="GEOM_AREA" nillable="true" type="xsd:double"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="GEOM_PERI" nillable="true" type="xsd:double"/>
           <xsd:element maxOccurs="1" minOccurs="0" name="BEGINLIFE" nillable="true" type="xsd:string"/>
         </xsd:sequence>                                                         
       </xsd:extension>                                                          
     </xsd:complexContent>                                                          </xsd:complexType>
    

  2. Ask for a feature using GetFeatureInfo and look at the returned attributes:
