.. attribute:: modifiable
Defaults to ``False``. When set to to ``True``, 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.

.. class:: OSMGeoAdmin
A subclass of :class:`GeoModelAdmin` that uses a spherical mercator projection
with OpenStreetMap street data tiles. See the :ref:`OSMGeoAdmin introduction <osmgeoadmin-intro>`
with `OpenStreetMap <http://openstreetmap.org/>`_ street data tiles.
See the :ref:`OSMGeoAdmin introduction <osmgeoadmin-intro>`
in the tutorial for a usage example.
