======================
GeoDjango's admin site
======================
.. module:: django.contrib.gis.admin
   :synopsis: GeoDjango's extensions to the admin site.
``GeoModelAdmin``
=================
.. class:: GeoModelAdmin
   .. attribute:: default_lon
   The default center longitude.
   .. attribute:: default_lat
   The default center latitude.
   .. attribute:: default_zoom
   The default zoom level to use.  Defaults to 18.
   .. attribute:: extra_js
   Sequence of URLs to any extra JavaScript to include.
   .. attribute:: map_template
   Override the template used to generate the JavaScript slippy map.
   Default is ``'gis/admin/openlayers.html'``.
   .. attribute:: map_width
   Width of the map, in pixels.  Defaults to 600.
   .. attribute:: map_height
   Height of the map, in pixels.  Defaults to 400.
   .. attribute:: openlayers_url
   Link to the URL of the OpenLayers JavaScript.  Defaults to
   ``'http://openlayers.org/api/2.11/OpenLayers.js'``.
   .. attribute:: modifiable
   Defaults to ``True``.  When set to ``False``, disables editing of
   existing geometry fields in the admin.
   .. note::
       This is different from adding the geometry field to
       :attr:`~django.contrib.admin.ModelAdmin.readonly_fields`,
       which will only display the WKT of the geometry. Setting
       ``modifiable=False``, actually displays the geometry in a map,
       but disables the ability to edit its vertices.
``OSMGeoAdmin``
===============
.. class:: OSMGeoAdmin
   A subclass of :class:`GeoModelAdmin` that uses a spherical mercator projection
   with `OpenStreetMap `_ street data tiles.
   See the :ref:`OSMGeoAdmin introduction `
   in the tutorial for a usage example.
