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.

The following spatial lookups are supported:

• contains

• disjoint

• distance_gt

• distance_gte

• distance_lt

• distance_lte

• dwithin

• intersects

• within

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

Added in version 6.0.1: Support for spatial lookups was added.

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).

• Spatial lookups don’t support subqueries or expressions.

• GIS aggregate functions and geographic database functions aren’t supported.

• RasterField isn’t supported.
