Method Detail

getLatitude

public abstract double getLatitude()

Returns:

geographic coordinate specified in decimal degrees.

getLongitude

public abstract double getLongitude()

Returns:

geographic coordinate specified in decimal degrees.

getAccuracy

public abstract double getAccuracy()

The accuracy attribute denotes the accuracy level of the latitude and longitude coordinates. It is specified in meters. The value of the accuracy attribute must be a non-negative number.

Returns:

accuracy in meters

getAltitude

public abstract Double getAltitude()

Denotes the height of the position, specified in meters above the ellipsoid. If the implementation cannot provide altitude information, the value of this attribute must be null.

Returns:

value in meters, may return null, if the information is not available

getAltitudeAccuracy

public abstract Double getAltitudeAccuracy()

The altitude accuracy is specified in meters. If the implementation cannot provide altitude information, the value of this attribute must be null. Otherwise, the value must be a non-negative real number.

Returns:

value in meters; may return null, if the information is not available

getHeading

public abstract Double getHeading()

Denotes the direction of travel of the device and is specified in degrees counting clockwise relative to the true north.

Returns:

value from 0 to 360 - may return null, if the information is not available

getSpeed

public abstract Double getSpeed()

Denotes the magnitude of the horizontal component of the device's current velocity and is specified in meters per second.

Returns:

may return null, if the information is not available
