Laravel Builder Mysql Spatial Extension

Laravel Builder extensions to calculate distances between two Spatial points using Mysql native function ST_Distance_Sphere.

ST_Distance_Sphere default unit to find distance is meters.

Installation

You can install the package via composer:

composer require magutti/magutti-spatial

Usage

Add in your Model

use Magutti\MaguttiSpatial\Builders\SpatialBuilder;

class Location extends Model
{
    .......
    // you can override the default longitude and latitude fields
    protected $spatialFields = [
        'lng',
        'lat'
    ];
   
    function newEloquentBuilder($query): SpatialBuilder
    {
        return new SpatialBuilder($query);
    }
    .......
}

Example of usage

Get all points where the distance from a given position are less than 1Km

Location::select(['id','lng','lat'])
           ->whitDistance([8.9246844, 45.4152695]) // return distance in meters (default)
           ->whereDistance([8.9246844, 45.4152695],1000)
           ->get()

where 8.9246844 (longitude), 45.4152695 (latitude) is your position and 1000 is the max distance in meters.

SELECT `id`,
       `lng`,
       `lat`,
       St_distance_sphere(Point(8.9246844, 45.4152695), Point(lng, lat)) * 1 AS
       distance
FROM   `locations`
WHERE  St_distance_sphere(Point(8.9246844, 45.4152695), Point(lng, lat)) < 1000 

Using Miles

Location::select(['id','lat','lng'])
           ->whitDistanceInMiles([8.9246844, 45.4152695]) // return distance in Miles
           ->whereDistance([8.9246844, 45.4152695],10,'mi')
           ->get()

Find the closest point to you in Km

Location::select(['id','lat','lng'])
           ->whitDistanceInKm([8.9246844, 45.4152695]) 
           ->whereDistance([8.9246844, 45.4152695],10,'km')
           ->closest()

Helpers

The package provide some pre-built methods to calculate distance in Km, Miles or Feet.

whitDistanceInKm(array $point)    -> return distance in Km;
whitDistanceInMiles(array $point) -> return distance in Miles (mi);
whitDistanceInFeet(array $point)  -> return distance in Feet (ft);

and for filtering by distance

whereDistanceInKm(array $point, float $distance)     -> filter point by a given distance in Km
whereDistanceInMiles(array $point, float $distance)  -> filter point by a given distance in Miles
whereDistanceInFeet(array $point, float $distance)   -> filter point by a given distance in Miles
