Coords¶

public structCoords

Geographic coordinates attached to a LocationEvent.

Members¶

accuracy¶

public let accuracy: Double?

Horizontal accuracy radius in meters.

altitude¶

public let altitude: Double?

Altitude above a reference plane in meters.

iOS¶

Altitude above mean sea level.

Android¶

Altitude above the WGS84 reference ellipsoid. See also ellipsoidal_altitude.

altitudeAccuracy¶

public let altitudeAccuracy: Double?

Vertical accuracy in meters. Returns -1 if unavailable.

iOS¶

When positive, the altitude value is within ±altitude_accuracy meters. When negative, altitude is invalid. Determining altitude accuracy requires a GPS-capable device; on some devices this value is always negative.

Android¶

Defined as the 1-sigma vertical accuracy at 68% confidence — the half-width of the range above and below altitude within which the true altitude has a 68% probability of falling.

ellipsoidalAltitude¶

public let ellipsoidalAltitude: Double?

Altitude above the WGS84 reference ellipsoid in meters.

heading¶

public let heading: Double?

Direction of travel in degrees (0–360, clockwise from true north).

Note

Only present when the location came from GPS. Returns -1 otherwise.

headingAccuracy¶

public let headingAccuracy: Double?

Heading accuracy in degrees.

Note

Only present when the location came from GPS. Returns -1 otherwise.

latitude¶

public let latitude: Double

Latitude in decimal degrees.

longitude¶

public let longitude: Double

Longitude in decimal degrees.

speed¶

public let speed: Double?

Ground speed in meters per second.

Note

Only present when the location came from GPS. Returns -1 otherwise.

speedAccuracy¶

public let speedAccuracy: Double?

Speed accuracy in meters per second.

Note

Only present when the location came from GPS. Returns -1 otherwise.
