Laravel Spatial

This Laravel package allows you to easily work with spatial data types and functions.

• v2 supports Laravel 10+ and PHP 8.1+
• v1 supports Laravel 8,9 and PHP 8.1+

This package supports MySQL v8 or v5.7, and MariaDB v10.

Getting Started

Installing the Package

You can install the package via composer:

composer require asanikovich/laravel-spatial

Configuration

Default Configuration file includes geometry types mapping:

<?php

use ASanikovich\LaravelSpatial\Enums\GeometryType;
use ASanikovich\LaravelSpatial\Geometry;

return [
    GeometryType::POINT->value => Geometry\Point::class,
    GeometryType::POLYGON->value => Geometry\Polygon::class,
    /// ...
];

You can publish the config file with:

php artisan vendor:publish --tag="laravel-spatial-config"

If you want you can override custom geometry types mapping:

• globally by config file
• by custom $casts in your model (top priority)

Setting Up Your First Model

1. First, generate a new model along with a migration file by running:

   php artisan make:model {modelName} --migration

2. 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->point('location')->nullable();
               $table->polygon('area')->nullable();
               $table->timestamps();
           });
       }
   
       public function down(): void
       {
           Schema::dropIfExists('places');
       }
   }

3. Run the migration:

   php artisan migrate

4. In your new model, fill $casts arrays and use the HasSpatial trait (fill the $fillable - optional):

   namespace App\Models;
   
   use Illuminate\Database\Eloquent\Model;
   use ASanikovich\LaravelSpatial\Eloquent\HasSpatial;
   use ASanikovich\LaravelSpatial\Geometry\Point;
   use ASanikovich\LaravelSpatial\Geometry\Polygon;
   
   /**
    * @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 ASanikovich\LaravelSpatial\Geometry\Polygon;
use ASanikovich\LaravelSpatial\Geometry\LineString;
use ASanikovich\LaravelSpatial\Geometry\Point;
use ASanikovich\LaravelSpatial\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]]]}

Further Reading

For more comprehensive documentation on the API, please refer to the API page.

Create queries only with scopes methods:

Place::whereDistance(...); // This is IDE-friendly

Extension

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
