This package is fully untested, undocumented and unstable and is a combination of the two great packages:
Installation made super-easy with composer:
composer require apptimists/laravel-spatial
Also add the LaravelSpatial\SpatialServiceProvider::class to your config/app.php.
Works with PostgreSQL installed PostGIS extension and MySQL at least version 5.6.
If you try using it on a shared host which is not fulfilling those requirements, change your provider.
We use the GeoJson PHP Library for describing spatial fields as GeoJSON object, e.g.:
use GeoJSON\Geometry\Point;
...
$eloquent = new MyModel();
$eloquent->location = new Point([49.7, 6.9]);
...
$eloquent->save();
