==Introduction==
The '''gis''' extension implements the [[/geo tag|''<geo>'' tag]],  the [[/map sources|''Map sources'']] and the [[/neighbors|''Neighbors'']] function, in addition to [[/maparea|support of other map resources]].

The extensions can be [[/installation|enabled individually]], but the concept is certainly more powerful when they are all enabled.

See also [[:en:Wikipedia:WikiProject Geographical coordinates|Wikipedia:WikiProject Geographical coordinates]] for more information.

=== Status ===

Currently the geo and map sources extensions are quite well developed, and have been tested for a time on an external server. Additionally, a few thousand articles in the en: Wikipedia are marked with geographic coordinates using an interim solution with templates, as a proof-of-concept.  They will be converted to the geo tag if this extension gets enabled for the English Wikipedia. That will also solve the current problem with coordinates as arguments for infobox templates. Collection of data points have been done with an interim, external solution based on some Perl scripts.

The database extension has also been implemented, and is available. But it is likewise not yet enabled for any of the Wikipedias.

=== Acknowledgements ===
Magnus Manske has been extremely helpful in the work on integration with Wikimaps.
I would also like to give a big thank you to all participants in WikiProject Geographical coordinates who have helped immensely with suggestions and practical work, and to Brion Vibber and others on [[mail:wikitech-l]] for very good advice.
