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.
geo_json = {
:type => 'Point',
:coordinates => [ -122.423246, 37.779388 ]
}
r.table('geo').insert({
:id => 'sfo',
:name => 'San Francisco',
:location => r.geojson(geo_json)
}).run(conn)
