The Maps Department creates and maintains system and route maps for use on road-transportation-related articles. The department is responsible for creating and maintaining a standard appearance for road-related maps. Any state is welcome here.

The department is also tasked with creating Keyhole Markup Language (KML) files for articles. The KML file specifies a set of features (place marks, images, polygons, textual descriptions, etc.) for display in Google Earth, online mapping services, or any other geospatial software. On Wikipedia, these files are used in two places. By converting KML to the GeoJSON format, we are able to create interactive maps for the infobox. The file also draws these lines on the popup WikiMiniAtlas that appears through the -icon in the top right corner of articles once a KML file is created and added using {{Attached KML}}.

A tutorial on how to make maps or KML files can be found here.

To doEdit

road articles need maps (update).
road articles need KML files (update).
  • Identify articles about routes that lack maps
  • Identify articles that need updated maps or maps more specific to a previous time period
  • Identify and categorize existing historical road maps
  • Tag existing maps to state they were created using open-source GIS data. (Important as copyright issues have been raised at image reviews)
  • Identify articles about routes that lack KML


Try to stick to the following standards when creating maps:


  • Upload all maps in PNG or SVG format. Preference is given to SVGs as they are easier to update when conditions change.


  • Use of the existing Interstate SVG shields (as well as state highway SVG shields, if available) is highly advised.
  • If you choose to use other shields, use the Roadgeek 2005 Fonts.

Map sizeEdit

  • Maps for infoboxes should be with a ratio of around 1.7:1 though a few pixels off isn't a big deal. PNG bitmaps should be about 290x172. SVG vector files should be set with a size of around 1450x860. Wikimedia is able to scale them down automatically and clicking on it will expand it to the nominal size.
  • Maps outside the infobox are fair game as far as size would be concerned.


  • Maps will use an implied legend of the above; if there is any deviation, a legend should be included on the map to prevent confusion.

KML filesEdit

In addition to maps, road articles can also contain a link to a KML file. KML files provide a series of coordinates that help locate the absolute position of the road in question. KML data can be reused outside of Wikipedia; it can be imported to geographic software, including GIS programs, and overlaid onto mapping services like Google Maps and Bing Maps.

Because KML files can be generated by the same data that is used when making maps, the Maps Task Force is also responsible for maintenance of the KML data that is attached to articles. For a tutorial on how to create KML files, see the /Tutorial.

KML data should be pasted into a subpage of Template:Attached KML that is named identically to the article. (For example, the KML of Oklahoma State Highway 82 is located at Template:Attached KML/Oklahoma State Highway 82. The article should then have {{Attached KML}} added to the external links section of the article, which provides links to both the raw KML data and also Google Maps and Bing Maps with the KML file overlaid.
