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 point-point distance strategy, defaults to haversine |
