(note WFS is know to be a hotchpotch for coordinate order, this particular server configuration seems to prefer lat-lon swapped: 50,0,55,10).

Filter (optional)


Amsterdam

It is possible to add filters to a request, using the description returned by the request=DescribeFeatureType, for instance http://geo.vliz.be/geoserver/wfs?service=WFS&request=GetFeature&typeName=World:worldcities&filter=<PropertyIsEqualTo><PropertyName>World:city_name</PropertyName><Literal>Amsterdam</Literal></PropertyIsEqualTo>

WFS features can be visualised and filtered very easy with QuantumGIS, just paste http://geo.vliz.be:80/geoserver/wfs?service=WFS in the WFS service menu of QuantumGIS.
