Calculate the geographical distance between 2 points with extreme accuracy.

Project Description

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)
>>> vincenty(boston, newyork, miles=True)


$ pip install vincenty
