It can be found on Packagist. The recommended way is through composer.

Edit compose.json and add:

    "require": {
        "toin0u/geotools-laravel": "~0.2"

And install dependecies:

$ curl -sS | php
$ php composer.phar install


Registering GeotoolsServiceProvider is required.


use Geotools\Silex\GeotoolsServiceProvider;

// .. create $app
$app->register(new GeotoolsServiceProvider());


Coordinate & Ellipsoid
