Function Documentation

void calc_gc_course_dist	(	const Point3D &	start,
		const Point3D &	dest,
		double *	course,
		double *	dist
	)			[inline]

Calculate course/dist given two spherical points.

Parameters:

	start	starting point
	dest	ending point
	course	resulting course
	dist	resulting distance

Point3D calc_gc_lon_lat	(	const Point3D &	orig,
		double	course,
		double	dist
	)			[inline]

Calculate new lon/lat given starting lon/lat, and offset radial, and distance.

NOTE: starting point is specifed in radians, distance is specified in meters (and converted internally to radians) ... assumes a spherical world.

Parameters:

	orig	specified in polar coordinates
	course	offset radial
	dist	offset distance

Returns:

destination point in polar coordinates
