Maps is the MediaWiki extension to visualize and work with geographical information. It has been maintained since 2009 and is installed on 1000+ wikis.


  • Powerful #display_map parser hook for embedding highly customizable dynamic maps into wiki pages.
  • Support for multiple mapping services: Leaflet, Google Maps and OpenStreetMap.
  • Integration with Semantic MediaWiki via a coordinate datatype
    • Query your stored coordinates and visualize them on dynamic maps, as tables or as lists
    • Export your coordinates as KML or RDF
    • Combine coordinates with other structured data stored in your wiki
  • Geocoding via several supported services with the #geocode parser function.
  • GeoJson support including a basic visual editor
  • Coordinate formatting and format conversion via the #coordinates parser function.
  • Geospatial operations
    • Calculating the distance between two points with #geodistance
    • Finding a destination given a starting point, bearing and distance with #finddestination
  • Distance formatting and format conversion via the #distance parser function.
  • Visual map editor (Special:MapEditor) to edit #display_map wikitext (requires Google Maps).

Project status


Project structure

The src/ contains the PHP code and follows PSR-4 autoloading.

  • src/DataAccess - implementations of services that use the network, read from disk or persistence services
  • src/Elements - Value Objects representing geographical elements (should be devoid of MediaWiki binding)
  • src/MediaWiki - MediaWiki hook points, including API modules, special pages and MediaWiki hooks
  • src/Presentation - presentation layer code (all code dealing with HTML etc should be here)
  • src/SemanticMW - Semantic MediaWiki hook points, including result printers and value descriptions

JavaScript, CSS and other web resources go into resources/.

Tests for PHP go into tests/ where they are grouped by test type (ie unit, integration). Within those test type directories the tests should mirror the directory structure in src/.

Running the tests

As setup, run composer install inside of the Maps root directory.

You can run the MediaWiki independent tests by executing phpunit in the root directory of maps:


This is possible without having a MediaWiki installation or webserver. A clone of the Maps code suffices.

If you do not have PHPUnit installed, you can download the .phar into the root directory and execute it there:

wget -O phpunit.phar
php phpunit.phar

To run the tests with MediaWiki, change into tests/phpunit of your MediaWiki installation and run

php phpunit.php --wiki wiki -c ../../extensions/Maps/phpunit.xml.dist

Where you either update wiki to match your wikis name, or drop the parameter. The above command works without modification if you are using the MediaWiki Vagrant.

Beware that due to technical debt, some tests access the network.
