# GeoDjango’s admin site

## `GeoModelAdmin`

#### `class GeoModelAdmin`

#### `default_lon`

The default center longitude.

#### `default_lat`

The default center latitude.

#### `default_zoom`

The default zoom level to use.  Defaults to 4.

#### `extra_js`

Sequence of URLs to any extra JavaScript to include.

#### `map_template`

Override the template used to generate the JavaScript slippy map.
Default is `'gis/admin/openlayers.html'`.

#### `map_width`

Width of the map, in pixels.  Defaults to 600.

#### `map_height`

Height of the map, in pixels.  Defaults to 400.

#### `openlayers_url`

Link to the URL of the OpenLayers JavaScript.  Defaults to
`'https://cdnjs.cloudflare.com/ajax/libs/openlayers/2.13.1/OpenLayers.js'`.

> **Changed in Django 1.11**
>
> Older versions default to
> `'http://openlayers.org/api/2.13.1/OpenLayers.js'`.

#### `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
> [`readonly_fields`](/pt-br/2.0/ref/contrib/admin/#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 [`GeoModelAdmin`](#django.contrib.gis.admin.GeoModelAdmin) that uses a Spherical Mercator projection
with [OpenStreetMap](https://www.openstreetmap.org/) street data tiles.
See the [OSMGeoAdmin introduction](/pt-br/2.0/ref/contrib/gis/tutorial/#osmgeoadmin-intro)
in the tutorial for a usage example.
