strategy::distance::haversine

Distance calculation for spherical coordinates on a perfect sphere using haversine.

template<typename RadiusTypeOrSphere, typename CalculationType>
class strategy::distance::haversine
{
  // ...
};

Parameter	Default	Description
typename RadiusTypeOrSphere	double	numeric type for radius (of sphere, earth) or sphere model
typename CalculationType	void	numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point

Function	Description	Parameters
haversine()	Default constructor, radius set to 1.0 for the unit sphere.
template<typename RadiusOrSphere> haversine(RadiusOrSphere const & radius_or_sphere)	Constructor.	RadiusOrSphere const &: radius_or_sphere: radius of the sphere or sphere model

Function

Description

Parameters

haversine()

Default constructor, radius set to 1.0 for the unit sphere.

template<typename RadiusOrSphere>
haversine(RadiusOrSphere const & radius_or_sphere)

Constructor.

RadiusOrSphere const &: radius_or_sphere: radius of the sphere or sphere model

Function	Description	Parameters	Returns
template<typename Point1, typename Point2> calculation_type< Point1, Point2 >::type apply(Point1 const & p1, Point2 const & p2)	applies the distance calculation	Point1 const &: p1: first point Point2 const &: p2: second point	the calculated distance (including multiplying with radius)
radius_type radius()	access to radius value		the radius
