This section is devoted to the WFS module. Description taken from project page:
This is a Web Feature Service implementation around Views and Drupal-stored geodata.
This is useful for users who must display many points on an OpenLayers map or complex data that would be poorly rendered by browsers. Essentially, GeoServer can pull node data from Drupal via WFS and display the points as a rendered image. Then the user can interact with the map by clicking and making WFS queries for point information.
