Member Function Documentation

Direct()

virtual SDKResult SDK_CALLTYPE Direct ( double  lat1, double  lon1, double  azi, double  dist, double &  lat2, double &  lon2  ) const throw ( )

pure virtual

Perform the direct geodesic calculation.

Parameters

[in]	lat1	Latitude of point 1 (degrees).
[in]	lon1	Longitude of point 1 (degrees).
[in]	azi	Azimuth at start point (degrees).
[in]	dist	Distance between point 1 and point 2 (NM). It can be signed.
[out]	lat2	Latitude of point 2 (degrees).
[out]	lon2	Longitude of point 2 (degrees). lat1 should be in the range -90, 90; lon1 and azi should be in the range -180,360. The value of lon2 returned is in the range -180,180

Inverse()

virtual SDKResult SDK_CALLTYPE Inverse ( double  lat1, double  lon1, double  lat2, double  lon2, double &  dist, double &  azi1, double &  azi2  ) const throw ( )

pure virtual

Perform the inverse geodesic calculation.

Parameters

[in]	lat1	Latitude of point 1 (degrees)
[in]	lon1	Longitude of point 1 (degrees)
[in]	lat2	Latitude of point 2 (degrees)
[in]	lon2	Latitude of point 2 (degrees)
[out]	dist	Distance between point 1 and point 2 (NM).
[out]	azi1	Azimuth at point 1 (degrees)
[out]	azi2	(forward) azimuth at point 2 (degrees)

GeodesicLine()

virtual SDKResult SDK_CALLTYPE GeodesicLine ( double  lat1, double  lon1, double  lat2, double  lon2, double  distance_between_wp, GeodesicLineType  type, geometry::IPointCollection **  points  ) const throw ( )

pure virtual

Perform the Great Circle approximation.

Parameters

[in]	lat1	Latitude of point 1 (degrees)
[in]	lon1	Longitude of point 1 (degrees)
[in]	lat2	Latitude of point 2 (degrees)
[in]	lon2	Latitude of point 2 (degrees)
[in]	distance_between_wp	Nominal distance between waypoints
[out]	points	Address of a variable that receives the points.
