ng-haversine

ng-haversine is an AngularJS module that applies the Haversine formula to a pair of coordinates to calculate the distance between them.

How to

The first step is to download the ng-haversine script. You can do it cloning this repo:

$ git clone https://github.com/vermicida/ng-haversine.git

Or via NPM:

$ npm install ng-haversine

Once the library is downloaded, make sure you are referencing it in your index.html, just after the AngularJS library reference:

<script src="./node_modules/ng-haversine/ng-haversine.min.js"></script>

You must inject the ng-haversine dependency within your module setter:

angular.module("test", ["dahr.ng-haversine"]);

Now, you are ready to go. You will need two coordinates given in the format below:

var coord1 = {
  "latitude": 40.4169473,
  "longitude": -3.7057172
};
 
var coord2 = {
  "latitude": 40.4236942,
  "longitude": -3.7109793
};

To calculate the distance between them, you must use the function distance() from the service $haversine:

var distance = $haversine.distance(coord1, coord2);

IMPORTANT: The distance is given in meters.
