The '''gis''' extension implements the [[Gis geo tag|''<geo>'' tag]], the [[Gis map sources|''Map sources'']] and the [[Gis neighbors|''Neighbors'']] function, in addition to supporting other map resources. |
|||
The map sources extension is the target of the <geo> tag wikilink, and provides a page of available Internet map resources, in a manner much like the ISBN resource page. The extension provides functionality to ''preload'' external URLs with coordinates, so that most maps are essentially one click away. |
|||
The extensions can be enabled individually, but the concept is certainly more powerful when they are all enabled. |
|||
There are currently 30 different built in replacement strings, supporting various form of specification of scaling and coordinates, such as UTM, OSGB36 and CH1903. |
|||
See also [[en:Wikipedia:WikiProject Geographical coordinates]] for more information. |
|||
There exists specialized versions of the map sources page for various regions (like US and GB). For the global version, there are at present preloaded pointers to around 20 different map engines. |
|||
== Status == |
|||
In addition to the maps, there is a pointer to http://GeoURL.org, which lists nearby resources on the Internet. |
|||
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. |
|||
There is also a direct link for the open source NASA World Wind software, allowing a new, interactive way of experiencing for aerial imagery and topological data. World Wind has a plug-in layer for Wikipedia articles that are tagged with a geographic coordinate. Note that this requires the <tt>worldwind</tt> URL tag to be enabled in Wikipedia. |
|||
The database extension has also been implemented, and is available. But it is likewise not yet enabled for any of the Wikipedias. |

The URL format is: |

Map sources
The map sources extension is the target of the <geo> tag wikilink, and provides a page of available Internet map resources, in a manner much like the ISBN resource page. The extension provides functionality to preload external URLs with coordinates, so that most maps are essentially one click away.
There are currently 30 different built in replacement strings, supporting various form of specification of scaling and coordinates, such as UTM, OSGB36 and CH1903.
There exists specialized versions of the map sources page for various regions (like US and GB). For the global version, there are at present preloaded pointers to around 20 different map engines.
In addition to the maps, there is a pointer to http://GeoURL.org, which lists nearby resources on the Internet.
There is also a direct link for the open source NASA World Wind software, allowing a new, interactive way of experiencing for aerial imagery and topological data. World Wind has a plug-in layer for Wikipedia articles that are tagged with a geographic coordinate. Note that this requires the worldwind URL tag to be enabled in Wikipedia.
The URL format is:
$mediawiki/extensions/gis/index.php?geo=GEOBODY
where GEOBODY has exactly the same format as the body of the geo tag.
The neighborhood function
Assuming the enabling of the gis database extension, there is also a function to display neighborhood articles in Wikipedia. It lists the articles with Wikilinks, and their distance and direction from the current point.
The URL format is:
$mediawiki/extensions/gis/index.php?near=GEOBODY&dist=DIST
where GEOBODY has exactly the same format as the body of the geo tag. If a type is specified, only points that use this particular type will be included. DIST is the max distance from the point in question, measured in kilometers.
