# Geo Distance formulas

[![Build Status](https://travis-ci.org/jaxgeller/node-geo-distance.svg)](https://travis-ci.org/jaxgeller/node-geo-distance)

+ Vincenty

+ Haversine

### Install

`$ npm install node-geo-distance --save`

### Use

```js

var geo = require('node-geo-distance');

--> {latitude:x, longitude:x}, {latitude:x, longitude:x}, callback(dist)

geo.vincenty(coord1, coord2, callback)

--> {latitude:x, longitude:x}, {latitude:x, longitude:x}

geo.vincentySync(coord1, coord2)

--> {latitude:x, longitude:x}, {latitude:x, longitude:x}, callback(dist)

geo.haversine(coord1, coord2, callback)

--> {latitude:x, longitude:x}, {latitude:x, longitude:x}

geo.haversineSync(coord1, coord2)

```

### Examples

```js

var geo = require('node-geo-distance');

// White house

var coord1 = {

  latitude: 38.8977330,

  longitude: -77.0365310

}

// Washington Monument

var coord2 = {

  latitude: 38.8894840,

  longitude: -77.0352790

}

geo.vincenty(coord1, coord2, function(dist) {

  console.log(dist);

});

var vincentyDist = geo.vincentySync(coord1, coord2);

geo.haversine(coord1, coord2, function(dist) {

  console.log(dist);

});

var haversineDist = geo.haversineSync(coord1, coord2);

```
