Introduction

Maps is a MediaWiki extension that provides the ability to visualize geographic data with dynamic, JavaScript based, mapping API's such as Google Maps and OpenLayers in your wiki pages. It has built-in support for geocoding, displaying maps, displaying markers, adding pop-ups, and more. Maps allows extensive customization of your maps, either per map, or via a general setting affecting all maps on your wiki. It is used by the Semantic Maps extension. (Maps, retrieved Aug 2013.

Geocoding

Geocoding allows to work with addresses instead of coordinates, i.e. geocoding can convert something like 40 boulevard du Pont d'Arve, Geneva into coordinates.

Live example:

{{#geocode:40 bd du Pont-d'Arve, Genève}}
gives: 46° 11' 41.42" N, 6° 8' 24.91" E
{{#geocode:location=40 bd du Pont-d'Arve, Genève|format=float}}
gives: 46.194839 N, 6.140253 E
{{#geocode:location=40 bd du Pont-d'Arve, Genève|format=float|directional=no}}
gives: 46.194839, 6.140253

See more example in the official manual

Displaying Maps

In order to display map with one or more markers, you can either enter addresses that will be resolved by a geocoding service (see above) or coordinates.

One either can use a parser function or XML code.

Parser function:
{{#display_map:....}}
XML code:
<display_map>...</display_map>

Simple syntax example:

{{#display_map:<your location>|height=<some height>|service=<your service>|zoom=<zoom-level>}}

Read the official documentation, though there are new parameters which are not yet documented.

Parameters for #display_map

As of August 2013, parameters for #display_map version 3.0 are not yet officially documented, but look at Jeroen De Dauw list. Some Examples at semantic-mediawiki.org are broken.

Some extra parameters (to be tested...)

Simple examples

Most basic use example (result not shown):

{{#display_map:Genève}}
{{#display_map:}}

Below are some simple examples using height and width and zoom parameters.

{{#display_map:Geneva, Switzerland|height=200px|width=400px|zoom=6}}

{{#display_map:Geneva, Switzerland|width=400px|service=openlayers}}

Installation and configuration

Installation

In order to install a bleeding edge 3.0 alpha version, we did the following in this wiki:

  • Upgrade PHP to 5.3.10 (i.e. the default in Ubuntu 12.04)
  • Upgrade both the Wiki and all SMW extensions to developer (alpha) code
cd extensions:
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/DataValues.git
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/Validator.git
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/Maps.git

Configuration

You can use Maps out of the box. However, some services require API keys and according configuration settings in LocaSettings.php.
