Web Feature service

Creating a request to access a layer through WFS is not so different from WMS. However, the output is very different; with WFS, you get a vector representation of the data in a textual or binary format. The following code snippet is a request for the Packt:places layer:

     http://localhost:8080/geoserver/Packt/ows? 
     service=WFS& 
     version=1.0.0& 
     request=GetFeature& 
     typeName=Packt:places& 
     maxFeatures=50& 
     outputFormat=text/xml; subtype=gml/2.1.2

As we did previously with WMS, we are now going to discuss each parameter:

Parameter	Description
`service`	Explains to GeoServer what kind of request you are sending. The value is WFS as we want to retrieve a vector representation of the data.
`version`	Indicates the specific version of WFS you want to use.
`request`	Defines what operation you are requesting, among those supported by the service, GetFeature is the basic request to obtain data.
`typeName`	Specifies what layer should be used to...
