Geo

@Serializable(with = Geo.Serializer::class)

sealed class Geo : BsonFieldWriteable(source)

GeoJSON types supported by MongoDB.

Our goal is to represent the GeoJSON RFC, as it is implemented by MongoDB. MongoDB does not support large sections of the RFC, so we won't support them either.

GeoJSON operators calculate on a sphere, using the WGS84 reference system.
