Kartographer is a MediaWiki extension that adds map capability See https://www.mediawiki.org/wiki/Extension:Kartographer

You will need to run your own map tile server, or use one that is available to you. See https://wiki.openstreetmap.org/wiki/Tile_servers

Developer info

Many parts of the JavaScript that builds the dynamic maps and provides the GeoJSON might be used by tools and Gadgets outside of the Wikimedia extension realm so dependencies and requirements on this interface may be hard to discover. Be extra careful changing these without notice if they're not explicitly marked private and especially if they are marked public.
