strategy::distance::cross_track

Strategy functor for distance point to segment calculation.

Class which calculates the distance of a point to a segment, for points on a sphere or globe

template<typename CalculationType, typename Strategy>
class strategy::distance::cross_track
{
  // ...
};

Parameter	Default	Description
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
typename Strategy	haversine<double, CalculationType>	underlying point-point distance strategy, defaults to haversine

Function	Description	Parameters
cross_track()
cross_track(typename Strategy::radius_type const & r)		typename Strategy::radius_type const &: r:
cross_track(Strategy const & s)		Strategy const &: s:
