Accuracy in meters.
[iOS] Altitude above sea-level in meters. [Android] The altitude of this location in meters above the WGS84 reference ellipsoid.
Altitude accuracy in meters.
If this location does not have altitude_accuracy, then -1 is returned.
When this property contains 0 or a positive number, the value in the altitude property is plus or minus the specified number of meters. When this property contains a negative number, the value in the altitude property is invalid.
Determining the [altitudeAccuracy] requires a device with GPS capabilities. Thus, on some devices, this property always contains a negative value.
Android defines vertical accuracy at 68% confidence. Specifically, as 1-side of the 2-sided range above and below the estimated altitude reported by [altitude], within which there is a 68% probability of finding the true altitude.
In the case where the underlying distribution is assumed Gaussian normal, this would be considered 1 standard deviation.
For example, if [altitude] returns 150, and [verticalAccuracy] returns 20 then there is a 68% probability of the true altitude being between 130 and 170 meters.
The altitude of this location in meters above the WGS84 reference ellipsoid.
