WFS (OGC Web Feature Service)
===========================
This plugin reads vector data from an OGC `Web Feature Service`_ resource.
Example usage::
<model driver="feature_geom">
<features name="states" driver="wfs">
<url> http://demo.opengeo.org/geoserver/wfs</url>
<typename>states</typename>
<outputformat>json</outputformat>
</features>
...
Properties:
:url: Location from which to load feature data
:typename: WFS type name to access (i.e., the layer)
:outputformat: Format to return from the service; ``json`` or ``gml``
:maxfeatures: Maximum number of features to return for a query
:request_buffer: The number of map units to buffer bounding box requests with to ensure that enough data is returned.
This is useful when rendering buffered lines using the AGGLite driver.
