Question: how to calculate the distance between two latitude longitude points in python?
Answer: R = 6373.0. radius of the Earth. lat1 = math. radians(52.2296756) ...  lon1 = math. radians(21.0122287) lat2 = math. radians(52.406374) lon2 = math. radians(16.9251681) dlon = lon2 - lon1. change in coordinates. dlat = lat2 - lat1. a = math.
