- class aerospike.GeoJSON¶
Starting with version 3.7.0, the Aerospike server supports storing GeoJSON data. A Geo2DSphere index can be built on a bin which contains GeoJSON data, enabling queries for the points contained within given shapes using
geo_within_geojson_region()
andgeo_within_radius()
, and for the regions which contain a point usinggeo_contains_geojson_point()
andgeo_contains_point()
.On the client side, wrapping geospatial data in an instance of the
aerospike.GeoJSON
class enables serialization of the data into the correct type during write operation, such asput()
. On reading a record from the server, bins with geospatial data it will be deserialized into aGeoJSON
instance.See also

(k, m, b) = client.get(('test', 'pads', 'launchpad1')) print(b) client.close()
- class GeoJSON([geo_data])¶
Optionally initializes an object with a GeoJSON
str
or adict
of geospatial data.
- unwrap() dict of geospatial data ¶
Gets the geospatial data contained in the
GeoJSON
class.- Returns
a
dict
representing the geospatial data.
New in version 1.0.53.
