GeoQuerySet.centroid(**kwargs) Deprecated since version 1.9: Use the Centroid function instead. Availability: PostGIS, Oracle, SpatiaLite Returns the centroid value for the geographic field in a centroid attribute on each element of the GeoQuerySet.

GeoQuerySet.envelope(**kwargs) Deprecated since version 1.9: Use the Envelope function instead. Availability: PostGIS, SpatiaLite Returns a geometry representing the bounding box of the geometry field in an envelope attribute on each element of the GeoQuerySet.

GeoQuerySet.difference(geom) Deprecated since version 1.9: Use the Difference function instead. Returns the spatial difference of the geographic field with the given geometry in a difference attribute on each element of the GeoQuerySet.

GeometryField.dim This option may be used for customizing the coordinate dimension of the geometry field. By default, it is set to 2, for representing two-dimensional geometries. For spatial backends that support it, it may be set to 3 for three-dimensional support. Note At this time 3D support is limited to the PostGIS spatial backend.

GeoQuerySet.area(**kwargs) Deprecated since version 1.9: Use the Area function instead. Returns the area of the geographic field in an area attribute on each element of this GeoQuerySet.

GeometryField.geography If set to True, this option will create a database column of type geography, rather than geometry. Please refer to the geography type section below for more details. Note Geography support is limited to PostGIS and will force the SRID to be 4326.

class GeoManager The GeoManager is required in order to use the legacy GeoQuerySet Methods. Deprecated since version 1.9: All GeoQuerySet methods have been deprecated and replaced by equivalent database functions. As soon as the legacy methods have been replaced in your code, you should be able to remove the special GeoManager from your GIS-enabled classes. Changed in Django 1.9: In older versions, the manager was required to conduct geographic queries. Without it, all geographic filters
