LiveFlightQuery

public struct LiveFlightQuery

Use LiveFlightQuery to get filtered data as an array of LiveFlight objects or a GeoJSON string.

It will query locally cached data received previously. Used in SkyPath.liveFlights(with:).

  • An altitude range to query. Should be round to a thousand feet.

    The default is 0…52000. Measured in feet.

    Declaration

    Swift

    public var altRange: ClosedRange<Double>?

  • How to provide queried data. The default is items.

    Declaration

    Swift

    public var resultOptions: LiveFlightResultOptions

  • Polygon is a geo-fence area to fetch data inside only.

    Should be a closed ring. By default, it uses DataQuery.polygon. Typically you don’t need to set it. Optional.

    It is possible to set a custom polygon but the query is made among the locally stored data received by DataQuery configuration. So if the polygons are different there could be no data available locally.

    Declaration

    Swift

    public var polygon: [CLLocationCoordinate2D]?

  • Live flights are fetched periodically from the server, typically every minute, so the position could be outdated.

    Use it to calculate a predicted location based on the last known location, speed, and course.

    Declaration

    Swift

    public var predict: Bool

  • Default initializer.

    Declaration

    Swift

    public init(altRange: ClosedRange<Double>? = nil,
            resultOptions: LiveFlightResultOptions = .items,
            polygon: [CLLocationCoordinate2D]? = nil,
            predict: Bool = false)

    Parameters

    altRange

    When it’s nil all altitudes are used. Measured in feet. Optional.
    resultOptions

    See LiveFlightResultOptions for available options. The default is items.
    tiles

    Array of tile keys generated by Tile.key or Tile.keyByCoord. Use it to query items in the specific tiles. Optional.
    polygon

    Geo-fence area to fetch data inside only. Optional.
    predict

    If calculate predicted current location of the flight based on last received data. Optional. false by default.
