The List_of_pedestrian_zones would really be improved if it had Right? Unfortunately, It's not clear that it would be allowed. Even though OpenStreetMap identifies pedestrian streets for us, both drawing a polygon around them and calculating the area might be considered Original Research or Synthesis.
 * 1) Maps
 * 2) Some numerical measure of scale.

For now, I will keep these maps and numbers in this sandbox, but use them to rank the priority on what pedestrian zone information should be researched and added to the main article.

For additional notes on map technical issues, see below the table.

TODOs:
 * 1) Convert the map shapes from shaded to transparent. Stroke-color, fill-opacity, stroke-width, and other attributes are ignored when using "raw=" for inline GeoJSON.
 * 2) Standardize on Template:Maplink, convert Module:Mapframe entries.

The methodology used to create the polygons is to simply do the following:


 * 1) Query OpenStreetMap for "pedestrian ways".  This is done by going to http://overpass-turbo.eu and executing the following query:
 * 2) Draw a polygon that encloses contiguous pedestrian streets into a pedestrian zone.  If an edifice or space has an entrance on one of the pedestrian streets, the edifice is included.  If an edifice has an entrance on a non-pedestrian street, it is excluded.

Generating the polygons is easy. Introducing them to Wikipedia is far harder, though:
 * 1) There are policy issues, concerning Original Research or Synthesis.
 * 2) There are mechanical issues on storing map data.

With respect to the mechanical issues, there are at least four paths:


 * 1) Add Module:Mapframe tags or Template:Maplink templates to this page, and just inline the polygon.  The mechanical steps to do this are clear straight forward, but it is not a clean solution.
 * 2) Add the shape to WikiData.  The mechanical steps to do this are not well documented.  The citation requirements are vague, but it seems that one should be getting the shape data from a reliable, unrestricted publisher (for example, a government).
 * 3) Add the shape to WikiCommons.  The mechanical steps to do this are not well documented.  I have not found any citation requirements.
 * 4) Add the shape to OpenStreetMap, assign a QID, and just reference that QID from a maplink tag here.  (The "Het Funen" entry above uses this method, and an OpenStreetMap QID someone else has already created.)  The mechanical steps seem easier, but I'm not clear on the data source polices that are required by OpenStreetMap.
