The maps project aims to build cartography technologies for all Wikimedia projects, at a scale sufficient for their widespread usage. Please leave your feedback and ideas to help guide future development.

Cartographical efforts consist of several sub-projects:
 * At its core, the maps project uses Kartotherian map tile service. Kartotherian makes OpenStreetMap data available as image tiles, the map on which other tools can draw useful information. See.
 * Geoshapes service, part of Kartotherian, makes OpenStreetMap shapes data, such as countries, cities outlines, or even building outlines available directly to the clients via Wikidata IDs.
 * Kartographer extension allows editors to insert an interactive map and add article specific data into wiki pages. See.
 * GeoData extension allows articles to specify geographical coordinates, and expose them via search API.

Kartographer extension
Kartographer extension allows editors to insert a map and add article specific data into wiki pages, such as shapes and points of interest. Kartographer also has a Visual Editor interface to make it easy to add maps. Kartographer extension have been enabled in Wikivoyage and a few Wikipedia languages.

Other maps users

 * The Wikipedia Android app shows all nearby articles on a map using the Maps service.
 * The Wikidata query service uses maps to visualize query results.
 * Geohack, used by Wikipedia to provide links to various mapping services, uses the map tile service for the Russian and Italian Wikipedias . English, and other wiki's are planned for the future.

Production maps cluster
The production maps cluster (See also on Wikitech) is in development by the WMF Discovery team. The implementation has various components including:
 * Kartotherian Github (primary) / Gerrit (mirror) - a server capable of providing map tiles in vector (pbf) or raster (png) formats, as well as static map snapshots of any size for a given location.
 * Tilerator Github (primary) / Gerrit (mirror) – a distributed backend tile generation service with a jobque
 * A flexible sources system to set up the needed storage and processing pipeline

A version of the tile server is now in operation at maps.wikimedia.org.
 * It serves tiles at URLs such as https://maps.wikimedia.org/osm-intl/11/327/791.png (bitmap) or …/791.json (OSM data – waterways, roads, place labels, etc.).
 * It can scale images for the high-DPI devices – e.g. 1.5x, 2x, etc …/791@1.3x.png
 * It can provide static maps with a given size and scaling, e.g. https://maps.wikimedia.org/img/osm-intl,6,44.8247,4.9981,1000x600.png
 * For now, maps.wikimedia.org only accepts requests from the domains in,  , or.
 * https://maps.wikimedia.org/ is a simple map server that serves the Leaflet JavaScript library and some static files to provide a pannable, zoomable map using the Production maps cluster.
 * Please adapt your own labs tools to use !  Set your tool's domain to.
