Strategy functor for distance point to segment calculation.
Class which calculates the distance of a point to a segment, using latlong points
template<typename Point, typename PointOfSegment, typename CalculationType, typename Strategy> class strategy::distance::cross_track { // ... };
Parameter 
Default 
Description 

typename Point 
point type 

typename PointOfSegment 
Point 
segment point type 
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 
typename services::default_strategy<point_tag, Point>::type 
underlying pointpoint distance strategy, defaults to haversine
