Array

extension Array where Element == CLLocationCoordinate2D
public extension Array where Element == LiveFlight
public extension Array where Element == NowcastItem
public extension Array where Element == TurbulenceItem

Available where Element == CLLocationCoordinate2D

  • Generates a geodesic polyline coordinates using MapKit.MKGeodesicPolyline.

    When a line crosses Antimerdian it will have longitude from both sides, like +179° and -179°. This leads to a drawing over the whole globe.

    The result coordinates will be normalized into [-360°,0°] or [0°, +360°] longitude range. Warning. Longitude below -180° or above +180° is not a valid coordinate so the map library or parser could throw an error.

    Declaration

    Swift

    public var geodesic: [CLLocationCoordinate2D] { get }

  • Generates a corridor polygon.

    Declaration

    Swift

    public func buffer(widthNM: Double,
                   simplify: Bool = true,
                   tolerance: Double = 0.1) -> [CLLocationCoordinate2D]

    Parameters

    widthNM

    The width of corridor in nautical miles.
    simplify

    If the polygon should be simplified. true by default.
    tolerance

    Controls the level of simplification by specifying the maximum allowed distance between the original line point and the simplified point. A higher tolerance value results in higher simplification. 0.1 is good for server fetch and 0.01 is good for drawing on the map. The default is 0.1.

  • Simplifies the polygon.

    Declaration

    Swift

    public func simplify(tolerance: Double = 0.1) -> [CLLocationCoordinate2D]

    Parameters

    tolerance

    Controls the level of simplification by specifying the maximum allowed distance between the original line point and the simplified point. A higher tolerance value results in higher simplification. The default is 0.1.

  • Finds an intersection between two polygons.

    Declaration

    Swift

    public func intersection(with polygon: [CLLocationCoordinate2D]) -> [CLLocationCoordinate2D]?

    Parameters

    polygon

    The polygon to check intersection with.

  • Smooth the polygon using the Ramer–Douglas–Peucker algorithm.

    Performed on the caller queue and when lot of coordinates it could take some time, so using a background queue is recommended.

    Declaration

    Swift

    public func smoothed(iterations: Int = 1) -> [CLLocationCoordinate2D]

    Parameters

    iterations

    Controls the level of smoothness. A higher number results in higher smoothness. The default is 1.

Available where Element == LiveFlight

  • Converts the array of LiveFlight to a valid GeoJSON that can be visualized on the map.

    Can be used when you have a custom filtering of LiveFlight but need a GeoJSON for the map.

    Declaration

    Swift

    func geoJSON() -> String

Available where Element == NowcastItem

  • Converts the array of NowcastItem to a valid GeoJSON that can be visualized on the map.

    Declaration

    Swift

    func geoJSON() -> String

Available where Element == TurbulenceItem

  • Converts the array of TurbulenceItem to a valid GeoJSON that can be visualized on the map.

    Can be used when you have a custom filtering of TurbulenceItem but need a GeoJSON for the map.

    Declaration

    Swift

    func geoJSON(withType type: TurbulenceResultType) -> String

    Parameters

    type

    The feature geometry of turbulence in GeoJSON can be different for own (circle) and server (hexagon) turbulence.
