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 |
|
