How to calculate distance between the two places on the map? The simplest way is by using the formula for calculating the haversine, which for the given coordinates returns the distance of the points on the sphere. However, this is the air distance. If you are planning to take off on the road, you are surely interested in getting from point A to point B by traffic.
