|
pure virtual |
Returns the approximate initial bearing in degrees East of true North when traveling along the shortest path between this location and the given location.
The shortest path is defined using the WGS84 ellipsoid. Locations that are (nearly) antipodal may produce meaningless results.
| dest | The destination location. |
|
pure virtual |
Returns the approximate distance in meters between this location and the given location.
Distance is defined using the WGS84 ellipsoid.
| dest | The destination location. |
|
pure virtual |
Get the altitude if available, in meters above sea level.
If this location does not have an altitude then Float::NaN is returned.
|
pure virtual |
Get the bearing, in degrees.
Bearing is the horizontal direction of travel of this device, and is not related to the device orientation. It is guaranteed to be in the range (0.0, 360.0] if the device has a bearing.
If this location does not have a bearing then Float::NaN is returned.
|
pure virtual |
Get the estimated horizontal accuracy of this location, in meters.
If this location does not have an accuracy then Float::NaN is returned.
|
pure virtual |
Get the provider if available.
If this location does not have a provider then -1 is returned.
|
pure virtual |
Get the speed if it is available, in meters/second over ground.
If this location does not have a speed then Float::NaN is returned.
|
pure virtual |
Get the estimated vertical accuracy of this location, in meters.
If this location does not have an accuracy then Float::NaN is returned.
