GeoDjango

Django MongoDB Backend supports GeoDjango.

Each model field stores data as GeoJSON objects.

• PointField

• LineStringField

• PolygonField

• MultiPointField

• MultiLineStringField

• MultiPolygonField

• GeometryCollectionField

All fields have a 2dsphere index created on them.

You can use any of the geospatial query operators or the geospatial aggregation pipeline stage in raw_aggregate() queries.

Configuration

1. Install the necessary Geospatial libraries (GEOS and GDAL).

2. Add django.contrib.gis to INSTALLED_APPS in your settings. This is so that the gis templates can be located – if not done, then features such as the geographic admin or KML sitemaps will not function properly.

Limitations

• MongoDB doesn’t support any spatial reference system identifiers (BaseSpatialField.srid) besides 4326 (WGS84).

• None of the GIS QuerySet APIs (lookups, aggregates, and database functions) are supported.

• RasterField isn’t supported.
