Geo Laravel Package
brick/geo
brick/geo is a PHP geometry library for working with points, lines, polygons, and other shapes. Provides common spatial operations, parsing/formatting, and robust value objects to model geo data cleanly in applications and services.
GIS geometry library for PHP
Frequently asked questions about Geo
- How do I install brick/geo in a Laravel project?
- Run `composer require brick/geo` in your project root. The package is dependency-free and integrates directly with PHP, so no additional setup is needed beyond requiring it in your `composer.json`. For Laravel-specific features like Eloquent spatial queries, pair it with a spatial database like PostGIS.
- Does brick/geo support Laravel Eloquent for geospatial queries?
- Yes, brick/geo works alongside Eloquent by providing value objects for spatial logic. For PostGIS, use Laravel’s query builder with `ST_Distance` or `ST_Intersects` functions. MySQL Spatial is supported but lacks advanced PostGIS features. Custom query scopes can bridge the gap for basic operations.
- What Laravel versions does brick/geo officially support?
- brick/geo is a PHP library with no Laravel-specific dependencies, so it works with any Laravel 8.x+ version. Test thoroughly with your target Laravel version, as some spatial database drivers (e.g., PostGIS) may have version-specific quirks. Check the package’s PHP version requirements (typically 8.0+) for compatibility.
- Can I use brick/geo without PostgreSQL/PostGIS?
- Yes, but with limitations. For pure PHP operations (e.g., distance calculations, basic geometry validation), no database is required. MySQL Spatial supports simple functions like `ST_Distance_Sphere`, but advanced features (e.g., polygon operations) may need PostGIS. Test performance for high-volume use cases.
- How accurate are distance calculations in brick/geo?
- Distance calculations use PHP’s `float` arithmetic, which can introduce precision errors for very large distances (e.g., antipodal coordinates). Validate results against known benchmarks or use PostGIS’s `ST_Distance` for higher accuracy. Cache frequent calculations in Redis to mitigate performance costs.
- Is brick/geo suitable for real-time geofencing in Laravel?
- Yes, but design carefully. Use brick/geo’s `Point` and `Polygon` objects to define geofences, then query PostGIS with `ST_Intersects` for real-time checks. For high-traffic apps, offload computations to a queue (e.g., Laravel Queues) and cache results to avoid database locks.
- How do I serialize brick/geo geometries to GeoJSON for frontend use?
- Use the `toGeoJson()` method on brick/geo objects (e.g., `Point`, `Polygon`) to generate GeoJSON strings. Pass this directly to JavaScript libraries like Leaflet or Mapbox. For APIs, return GeoJSON in responses with `response()->json()` or Laravel’s `JsonResponse`.
- Are there alternatives to brick/geo for Laravel geospatial needs?
- For PostGIS-heavy apps, consider `doctrine/dbal` for direct database queries. For pure PHP with simpler needs, `turf/turf-php` offers similar geometry operations but with a different API. Evaluate trade-offs: brick/geo excels in Laravel integration, while alternatives may offer broader GIS features.
- How do I handle invalid geometries (e.g., self-intersecting polygons) in brick/geo?
- Use brick/geo’s `isValid()` method to check geometries before operations. Invalid geometries throw exceptions during creation or validation. For user-uploaded data, implement a validation pipeline (e.g., Laravel Form Requests) to reject malformed inputs early.
- What’s the best way to test brick/geo in a Laravel app?
- Write unit tests with PestPHP or PHPUnit to verify geometry operations (e.g., `assertTrue($polygon->contains($point))`). Mock spatial database queries for Eloquent tests. Use `brick/geo`'s built-in assertions for validation. For integration tests, seed spatial data in a test PostGIS/MySQL database.
