Creating an Auto-Refreshing Layer
=================================

Making layers automatically refresh is a new feature as of GeoMOOSE 2.8.  This is built-in,
no need for extensions or additional libraries.

How to do it
------------

Find the ``<map-source>`` which should auto-refresh.  Add the ``auto-refresh`` attribute to it.

For example:
::

	<map-source name="vehicle-locations" auto-refresh="15000">
		<layer name="buses"/>
		<layer name="trucks"/>
		<layer name="tractors"/>
	</map-source>



The ``auto-refresh`` is specified in milliseconds.  The example above will refresh the layer every 15 seconds.
