Increased accuracy (full double precision accuracy vs 0. geopy relies on online services whereas pyproj is local (meaning it will be faster and won't rely on an internet connection) and more transparent about its methods (see here for instance), which are based on the Proj4 codebase that underlies essentially all open-source GIS software. Incidentally, these magic numbers of 111,111 are easy to remember by knowing some history: the French originally defined the meter so that 10^7 meters would be the distance along the Paris meridian from the equator to the north pole. StringIO("""CLUSTER CLIENT LATITUDE LENGHT 0 X1 19. I'd recommend you use pyproj instead of geopy. distance. If the distance between the strings is higher than that, -1 is returned. meters, .
