Coords¶

Geographic coordinates attached to a Location.

Members¶

accuracy¶

double accuracy

Horizontal accuracy radius in meters.

altitude¶

double altitude

Altitude above a reference plane in meters.

iOS¶

Altitude above mean sea level.

Android¶

Altitude above the WGS84 reference ellipsoid. See also ellipsoidal_altitude.

altitude_accuracy¶

double altitudeAccuracy

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.

ellipsoidal_altitude¶

double ellipsoidalAltitude

Altitude above the WGS84 reference ellipsoid in meters.

floor¶

int? floor

iOS only The floor within a building, when the device is in a venue with indoor positioning.

iOS sends null when it reports no floor, which is almost always. Android never sends it. Test it with floor != null. In TypeScript, a floor !== undefined check lets iOS's null through, and if (floor) skips floor 0.

heading¶

double heading

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

Note

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

heading_accuracy¶

double headingAccuracy

Heading accuracy in degrees.

Note

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

latitude¶

double latitude

Latitude in decimal degrees.

longitude¶

double longitude

Longitude in decimal degrees.

speed¶

double speed

Ground speed in meters per second.

Note

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

speed_accuracy¶

double speedAccuracy

Speed accuracy in meters per second.

Note

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