Pregeneralized Features
=======================

.. note:: GeoServer does not come built-in with support for Pregeneralized Features; it must be installed through an extension.

Installing the Pregeneralized Features extension
------------------------------------------------

#. Download the Pregeneralized Features extension from the `GeoServer download page 
   <http://geoserver.org/display/GEOS/Download>`_.

   .. warning:: Make sure to match the version of the extension to the version of the GeoServer instance!

#. Extract the contents of the archive into the ``WEB-INF/lib`` directory of the GeoServer installation.

Adding a Pregeneralized Features data store
-------------------------------------------

If the extension is properly installed, :guilabel:`Generalized Data Store` will be listed as an option when creating a new data store.
