Laravel Eloquent Spatial
This Laravel package allows you to easily work with spatial data types and functions.
Supported databases:
- MySQL 5.7/8
- MariaDB 10
- Postgres 12/13/14/15/16 with PostGIS 3.4
Getting Started
Installing the Package
You can install the package via composer:
composer require matanyadaev/laravel-eloquent-spatial
Setting Up Your First Model
-
First, generate a new model along with a migration file by running:
php artisan make:model {modelName} --migration
-
Next, add some spatial columns to the migration file. For instance, to create a "places" table:
use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; class CreatePlacesTable extends Migration { public function up(): void { Schema::create('places', static function (Blueprint $table) { $table->id(); $table->string('name')->unique(); $table->geometry('location', subtype: 'point')->nullable(); $table->geometry('area', subtype: 'polygon')->nullable(); $table->timestamps(); }); } public function down(): void { Schema::dropIfExists('places'); } }
-
Run the migration:
php artisan migrate
-
In your new model, fill the
$fillable
and$casts
arrays and use theHasSpatial
trait:namespace App\Models; use Illuminate\Database\Eloquent\Model; use MatanYadaev\EloquentSpatial\Objects\Point; use MatanYadaev\EloquentSpatial\Objects\Polygon; use MatanYadaev\EloquentSpatial\Traits\HasSpatial; /** * @property Point $location * @property Polygon $area */ class Place extends Model { use HasSpatial; protected $fillable = [ 'name', 'location', 'area', ]; protected $casts = [ 'location' => Point::class, 'area' => Polygon::class, ]; }
Interacting with Spatial Data
After setting up your model, you can now create and access spatial data. Here's an example:
use App\Models\Place;
use MatanYadaev\EloquentSpatial\Objects\Polygon;
use MatanYadaev\EloquentSpatial\Objects\LineString;
use MatanYadaev\EloquentSpatial\Objects\Point;
use MatanYadaev\EloquentSpatial\Enums\Srid;
// Create new records
$londonEye = Place::create([
'name' => 'London Eye',
'location' => new Point(51.5032973, -0.1217424),
]);
$whiteHouse = Place::create([
'name' => 'White House',
'location' => new Point(38.8976763, -77.0365298, Srid::WGS84->value), // with SRID
]);
$vaticanCity = Place::create([
'name' => 'Vatican City',
'area' => new Polygon([
new LineString([
new Point(12.455363273620605, 41.90746728266806),
new Point(12.450309991836548, 41.906636872349075),
new Point(12.445632219314575, 41.90197359839437),
new Point(12.447413206100464, 41.90027269624499),
new Point(12.457906007766724, 41.90000118654431),
new Point(12.458517551422117, 41.90281205461268),
new Point(12.457584142684937, 41.903107507989986),
new Point(12.457734346389769, 41.905918239316286),
new Point(12.45572805404663, 41.90637337450963),
new Point(12.455363273620605, 41.90746728266806),
]),
]),
])
// Access the data
echo $londonEye->location->latitude; // 51.5032973
echo $londonEye->location->longitude; // -0.1217424
echo $whiteHouse->location->srid; // 4326
echo $vacationCity->area->toJson(); // {"type":"Polygon","coordinates":[[[41.90746728266806,12.455363273620605],[41.906636872349075,12.450309991836548],[41.90197359839437,12.445632219314575],[41.90027269624499,12.447413206100464],[41.90000118654431,12.457906007766724],[41.90281205461268,12.458517551422117],[41.903107507989986,12.457584142684937],[41.905918239316286,12.457734346389769],[41.90637337450963,12.45572805404663],[41.90746728266806,12.455363273620605]]]}

Extension
Extend Geometry class with macros
You can add new methods to the Geometry
class through macros.
Here's an example of how to register a macro in your service provider's boot
method:
class AppServiceProvider extends ServiceProvider
{
public function boot(): void
{
Geometry::macro('getName', function (): string {
/** @var Geometry $this */
return class_basename($this);
});
}
}
Use the method in your code:
$londonEyePoint = new Point(51.5032973, -0.1217424);
echo $londonEyePoint->getName(); // Point
Extend with custom geometry classes
You can extend the geometry classes by creating custom geometry classes and add functionality. You can also override existing methods, although it is not recommended, as it may lead to unexpected behavior.
- Create a custom geometry class that extends the base geometry class.
use MatanYadaev\EloquentSpatial\Objects\Point;
class ExtendedPoint extends Point
{
public function toCustomArray(): array
{
return 'coordinates' => [
'latitude' => $this->latitude,
'longitude' => $this->longitude
]
}
}
- Update the geometry class mapping in a service provider file.
use App\ValueObjects\ExtendedPoint;
use Illuminate\Support\ServiceProvider;
use MatanYadaev\EloquentSpatial\EloquentSpatial;
class AppServiceProvider extends ServiceProvider
{
public function boot(): void
{
EloquentSpatial::usePoint(ExtendedPoint::class);
}
}
- Update your model to use the custom geometry class in the
$casts
property orcasts()
method.
use App\ValueObjects\ExtendedPoint;
use Illuminate\Database\Eloquent\Model;
use MatanYadaev\EloquentSpatial\Traits\HasSpatial;
class Place extends Model
{
use HasSpatial;
protected $casts = [
'coordinates' => ExtendedPoint::class,
];
// Or:
protected function casts(): array
{
return [
'coordinates' => ExtendedPoint::class,
];
}
}
- Use the custom geometry class in your code.
use App\Models\Location;
use App\ValueObjects\ExtendedPoint;
$place = Place::create([
'name' => 'London Eye',
'coordinates' => new ExtendedPoint(51.5032973, -0.1217424),
]);
echo $place->coordinates->toCustomArray(); // ['longitude' => -0.1217424, 'latitude' => 51.5032973]
