Public Methods

Method	Description
CourseTo ( MapPoint me, MapPoint other ) : double	Calculates the course to use to travel to other lat/long pair. The course angle is expressed in degrees clockwise from North, in the range [0,360).
DistanceTo ( MapPoint me, MapPoint other ) : double	Calculates distance to other lat/long pair, and returns it. Uses the more exact formula for small distances.
Offset ( MapPoint me, double northDistanceInMeter, double eastDistanceInMeter, double heightDistanceInMeters ) : MapPoint	Offsets the current latitude/longitude values by given distances and returns a new value.
PolarOffset ( MapPoint me, double distanceInMeter, double bearingInDegrees, double heightDistanceInMeters ) : MapPoint	Offsets the current latitude/longitude values by polar distance and bearing in degrees and returns a new value. The bearing angle is expressed in degrees clockwise from North, in the range [0,360).

Method Details

CourseTo() public static method

Calculates the course to use to travel to other lat/long pair. The course angle is expressed in degrees clockwise from North, in the range [0,360).

public static CourseTo ( MapPoint me, MapPoint other ) : double
me	MapPoint	the map point object to calculate course from
other	MapPoint	other lat/long value
return	double

DistanceTo() public static method

Calculates distance to other lat/long pair, and returns it. Uses the more exact formula for small distances.

public static DistanceTo ( MapPoint me, MapPoint other ) : double
me	MapPoint	the map point object to calculate distance from
other	MapPoint	other lat/long value
return	double

Offset() public static method

Offsets the current latitude/longitude values by given distances and returns a new value.

public static Offset ( MapPoint me, double northDistanceInMeter, double eastDistanceInMeter, double heightDistanceInMeters ) : MapPoint
me	MapPoint	the map point object to offset
northDistanceInMeter	double	distance in north direction, in meters
eastDistanceInMeter	double	distance in east direction, in meters
heightDistanceInMeters	double	height distance, in meters
return	MapPoint

PolarOffset() public static method

Offsets the current latitude/longitude values by polar distance and bearing in degrees and returns a new value. The bearing angle is expressed in degrees clockwise from North, in the range [0,360).

public static PolarOffset ( MapPoint me, double distanceInMeter, double bearingInDegrees, double heightDistanceInMeters ) : MapPoint
me	MapPoint	the map point object to offset
distanceInMeter	double	distance to move, in meter
bearingInDegrees	double	/// bearing in degress, with 0 degrees being North, 90 being East, 180 being South and 270 /// being West. ///
heightDistanceInMeters	double	height distance, in meters
return	MapPoint
