AngularJS Haversine

A simple AngularJS module that uses the haversine formula to calculate the distance between two coordinates.

Adapted from haversine for Node.js by niix.

Changelog

• 2015-03-04 - v0.1.0 - Initial release.

Installation

bower install angular-haversine

Usage

Define the benharold.haversine dependency on your module and the haversine service will be available to you:

angular.module('myApp', ['benharold.haversine'])
    .controller('myController', [
        '$scope', 'haversine',
        function ($scope, haversine) {

            var start = {
                latitude: 30.849635,
                longitude: -83.24559
            };

            var end = {
                latitude: 27.950575,
                longitude: -82.457178
            };

            console.log(haversine(start, end));
            console.log(haversine(start, end, {unit: 'km'}));
            console.log(haversine(start, end, {threshold: 1}));
            console.log(haversine(start, end, {threshold: 1, unit: 'km'}));
        }
    ]);

Testing

I've tested this module against AngularJS 1.2 and 1.3. To run the unit tests, clone the repository and install the dependencies:

git clone https://github.com/benharold/angular-haversine.git /path/to/destination
cd /path/to/destination && npm install && bower install

Notice that I have the osx reporter defined as a dependency in package.json and enabled in karma.conf.js, so if you're on linux or Windows I assume you'll have to disable it. Now you can run karma:

karma start
