FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package laravel-geo
Geo Laravel
This is a fork from elevenlab/laravel-geo with some modifications for compatibility with Laravel 5.4+
Note: In this version you can use either geometry or geography column type for PostGIS with SRID.
Features
- GeoSpatial integration on Laravel 5.4+:
- Create geospatial columns using Schema and migrations
- Save and retrieve geospatial attributes using directly OpenGeoConsortium Spatial Objects (this package depends from PHP-OGC)
- Build spatial query directly with the laravel fluent query builder
- Supported types: Point, MultiPoint, Linestring, MultiLinestring, Polygon, MultiPolygon, GeometryCollection
- Supported drivers:
- Postgres: Posgis extension Extensions (geometry types)
- MySql: Extension for Spatial Data (geometry types)
Thanks to laravel-postgis for its original work.
Installation & Configuration

Install using composer
- Replace under the Service Providers section ('providers' array) in
config/app.phpthis line
with this one:
- If you need it, under the Alias section ('aliases' array) in config/app.php add this line:
Quick Documentation
Create table with spatial references
To add a geospatial field to your migration you can use these methods:
- point, multipoint linestring, multilinestring, polygon, multipolygon, geometrycollection
Example (NB: the schema is over-simplified):
Add spatial attributes to a Model
In order to handle dynamically geospatial attributes during CRUD operations, you need to:
- substitute the Eloquent Model abstract object with a custom Model
- define which attribute belongs to which geospatial type, defining the
$geometriesattribute (you can find here the available types)
Manipulate spatial attributes of a Model
Builds queries
There are two different groups of methods that are available, one to use the underlying database engine to perform spatial operations on existing objects, and another to build fluent queries and perform operations on database-resident data.
Given two OGCObjects, you can perform those operations:
-
intersection
-
difference
-
contains
-
intersects
-
touches
-
overlaps
-
centroid
-
distance
- equals
Given an illuminate Query Builder object, you can use:
-
whereEquals
-
whereNotEquals
-
orWhereEquals
-
orWhereNotEquals
-
whereContains
-
whereNotContains
-
orWhereContains
-
orWhereNotContains
-
whereIntersects
-
whereNotIntersects
-
orWhereIntersects
-
orWhereNotIntersects
-
whereTouches
-
whereNotTouches
-
orWhereTouches
-
orWhereNotTouches
-
whereOverlaps
-
whereNotOverlaps
-
orWhereOverlaps
- orWhereNotOverlaps
ToDo
- improve documentation
- add examples for "Build queries" section
- add manual installation guide
- add missing ST_functions
