Feature

@Serializable(with = FeatureSerializer::class)

data class Feature<out G : Geometry?, out P> @JvmOverloads constructor(val geometry: G, val properties: P, val id: String? = null, val bbox: BoundingBox? = null) : GeoJsonObject(source)

A Feature object represents a spatially bounded thing.

See RFC 7946 Section 3.2 for the full specification.

P

The type of properties. This can be any type that serializes to a JSON object. For dynamic or unknown property schemas, use JsonObject. For known schemas, use a Serializable data class.
