| A department of the U.S. Roads WikiProject | ||
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 do
|
726 |
| road articles need maps (). | |
 |
775 |
| road articles need KML files (). | |
- 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
Standards
Try to stick to the following standards when creating maps:
| Type | Stroke | Colorimetry |
|---|---|---|
| Road highlighted | 3 | #cc0000 R:204 G:0 B:0 |
| Toll highways Business routes |
3 | #008000 R:0 G:160 B:0 |

KML files
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.
GeoJSON
Wikipedia utilizes the Kartographer extension to display interactive maps using OpenStreetMap as a background. We can display map data on these maps by converting KML data to the GeoJSON format using User:Evad37/kmlToJson.js to do the conversion. Converted code can be used locally on pages such as Wikipedia:Map data/Wikipedia KML/Oklahoma State Highway 82 or at Commons at Data:Oklahoma State Highway 82.map.
Commons maps
Here is how to create a GeoJSON map on Commons. In the edit notice on any KML page, there is a link to the GeoJSON page here on enwiki and also the corresponding map page at Commons (Wikipedia:Map data/Wikipedia KML/Oklahoma State Highway 82 and Data:Oklahoma State Highway 82.map). When you click on the Commons link for the first time, you should be presented with content like this in the edit window. Edit the description, sources (optional), license (just remove // before your option), zoom, and coordinates accordingly. Then copy the GeoJSON code from the KML page (after conversion, of course) or the Map data page like Wikipedia:Map data/Wikipedia KML/Oklahoma State Highway 82. Then you can simply paste everything in the data field and overwrite { ... GeoJSON ... }. When you click save, an error will pop up, but that will only clear if you remove of the commented-out lines (those starting with //) in the code.
