# Geographic Feeds

GeoDjango has its own `Feed` subclass that may embed location information in RSS/Atom feeds formatted according to either the Simple GeoRSS or W3C Geo standards. Because GeoDjango’s syndication API is a superset of Django’s, please consult Django’s syndication documentation for details on general usage.

## Example

## API Reference

### `Feed` Subclass

class Feed

  In addition to methods provided by the `django.contrib.syndication.views.Feed` base class, GeoDjango’s `Feed` class provides the following overrides. Note that these overrides may be done in multiple ways:

      from django.contrib.gis.feeds import Feed

      class MyFeed(Feed):
          # First, as a class attribute.
          geometry = ...
          item_geometry = ...

          # Also a function with no arguments
          def geometry(self): ...

          def item_geometry(self): ...

          # And as a function with a single argument
          def geometry(self, obj): ...

          def item_geometry(self, item): ...

  geometry(obj)

  Takes the object returned by `get_object()` and returns the feed’s geometry. Typically this is a `GEOSGeometry` instance, or can be a tuple to represent a point or a box. For example:

      class ZipcodeFeed(Feed):
          def geometry(self, obj):
              # Can also return: `obj.poly`, and `obj.poly.centroid`.
              return obj.poly.extent  # tuple like: (X0, Y0, X1, Y1).

  item_geometry(item)

  Set this to return the geometry for each item in the feed. This can be a `GEOSGeometry` instance, or a tuple that represents a point coordinate or bounding box. For example:

      class ZipcodeFeed(Feed):
          def item_geometry(self, obj):
              # Returns the polygon.
              return obj.poly

### `SyndicationFeed` Subclasses

The following `django.utils.feedgenerator.SyndicationFeed` subclasses are available:

class GeoRSSFeed

class GeoAtom1Feed

class W3CGeoFeed

Informacja

W3C Geo formatted feeds only support `PointField` geometries.
