cyvincenty 1.0.0

Cython implementation of Vincenty distance.

Cyvincenty

A fast Cython implementation of the Vincenty algorithm for calculating the distance in kilometers between 2 co-ordinates.

This module is heavily inspired by uvincenty and vincenty. It is just as fast if not slightly faster than uvincenty which is a pure C Python extension despite being written in Python! (technically Cython).

Installation

pip install cyvincenty

Usage

>> from cyvincenty import vincenty

>> boston = (42.3541165, -71.0693514)
>> newyork = (40.7791472, -73.9680804)

>> cyvincenty(*boston, *newyork)
