<ogc:Function name="parameter"> <ogc:Literal>weightAttr</ogc:Literal> <ogc:Function name="env"> <ogc:Literal>weightAttr</ogc:Literal> <ogc:Literal>population</ogc:Literal> </ogc:Function> </ogc:Function> you define the weightAttr of the Process with the flexibilty for weightAttr as key of the env that can be changed by user on client side. The <ogc:Literal>population</ogc:Literal> is then only the default value, when no weightAttr value is sended in the env parameter of the request. You can leave that. You can also change the key to something else like "userattribute", than it looks like this: <ogc:Function name="parameter"> <ogc:Literal>weightAttr</ogc:Literal> <ogc:Function name="env"> <ogc:Literal>userattribute</ogc:Literal> <ogc:Literal>population</ogc:Literal> </ogc:Function> </ogc:Function> The request looks like this ....env=userattribute:population2;radius:44;pixelsPerCell:20....
