geojson
ReQL command: geojson
Command syntax
r.geojson(geojson) → geometry
Description
Convert a GeoJSON object to a ReQL geometry object.
RethinkDB only allows conversion of GeoJSON objects which have ReQL equivalents: Point
, LineString
, and Polygon
. MultiPoint
, MultiLineString
, and MultiPolygon
are not supported. (You could, however, store multiple points, lines and polygons in an array and use a geospatial multi index with them.)
Only longitude/latitude coordinates are supported. GeoJSON objects that use Cartesian coordinates, specify an altitude, or specify their own coordinate reference system will be rejected.
Example: Convert a GeoJSON object to a ReQL geometry object.
import com.rethinkdb.model.Geojson; // GeoJSON object: // { // "type": "Point", // "coordinates": [ -122.423246, 37.779388 ] // } Geojson geo = r.hashMap("type, "Point") .with("coordinates", r.array(-122.423246, 37.779388)); r.table("geo").insert( r.hashMap("id", "sfo") .with("name", "San Francisco") .with("location", r.geojson(geo)) ).run(conn);
