Calculate the geographical distance between 2 points with extreme accuracy.
Calculate the geographical distance (in kilometers or miles) between 2 points with extreme accuracy.
This library implements Vincenty’s solution to the inverse geodetic problem. It is based on the WGS 84 reference ellipsoid and is accurate to within 1 mm (!) or better.
This formula is widely used in geographic information systems (GIS) and is much more accurate than methods for computing the great-circle distance (which assume a spherical Earth).
Example: distance between Boston and New York City
>>> from vincenty import vincenty >>> boston = (42.3541165, -71.0693514) >>> newyork = (40.7791472, -73.9680804) >>> vincenty(boston, newyork) 298.396057 >>> vincenty(boston, newyork, miles=True) 185.414657
$ pip install vincenty
