Geo

Lightweight value types for geographic coordinates, used by DataFilter.Field.WithinGeoBounds and the MongoDB integration.

GeoLocation

data class GeoLocation(
    val lng: Double,
    val lat: Double,
    val lngLat: List<Double> = listOf(lng, lat)
)

GeoLocation.normalised(lng, lat) clamps the longitude to [-180, 180] and the latitude to [-90, 90].

GeoBoundingBox

A rectangle expressed as south-west and north-east corners.

data class GeoBoundingBox(
    val southWest: GeoLocation,
    val northEast: GeoLocation
) {
    val points: List<GeoLocation>          // clockwise rectangle corners
    fun toLngLatString(): String           // "swLng,swLat,neLng,neLat"
    fun toLatLngString(): String           // "swLat,swLng,neLat,neLng"
    fun pad(delta: Double): GeoBoundingBox

    companion object {
        operator fun invoke(bbox: List<Double>): GeoBoundingBox
        operator fun invoke(vararg bbox: Double): GeoBoundingBox
        fun fromLngLatString(bbox: String): GeoBoundingBox
        fun fromLatLngString(bbox: String): GeoBoundingBox
    }
}
