Calculate the distance of two geometries using the specified strategy.
The free function area calculates the area of a geometry. using the specified strategy. Reasons to specify a strategy include: use another coordinate system for calculations; construct the strategy beforehand (e.g. with the radius of the Earth); select a strategy when there are more than one available for a calculation.
template<typename Geometry1, typename Geometry2, typename Strategy> strategy::distance::services::return_type< Strategy, typename point_type<Geometry1>::type, typename point_type<Geometry2>::type >::type distance(Geometry1 const & geometry1, Geometry2 const & geometry2, Strategy const & strategy)
