Layer groups
============

The REST API allows you to create and modify layer groups in GeoServer.

.. note:: The examples below specify global layer groups, but the examples will work in a workspace-specific construction as well.

.. note:: Read the :api:`API reference for /layergroups <layergroups.yaml>`.

Creating a layer group
----------------------

**Create a new layer group based on already-published layers**


Given the following content saved as :file:`nycLayerGroup.xml`:

.. code-block:: xml

   <layerGroup>
     <name>nyc</name>
     <layers>
       <layer>roads</layer>
       <layer>parks</layer>
       <layer>buildings</layer>
     </layers>
     <styles>
       <style>roads_style</style>
       <style>polygon</style>
       <style>polygon</style>
     </styles>
   </layerGroup>
