Length scale with leaflet maps

[Tywyn]

I am using compound_query to display maps of different items:

{{#compound_query:
   [[Category:Metzgerei]]  ; ?Koordinaten
   | format=leaflet
   | cluster=on
   | height=600
   | width=1024
}}

Is there a way to display a length scale in a corner (e.g. lower right) so see, how far things are approximately from each other?
If there is a way, please recategorize this posting as a "question", otherwise I would like to ask for a feature request.

Cheers
Rainer

It does not have anything to do with the compound query. While Google maps automatically displays the scale on the map, leafleat maps don't do that (or it is not implemented in maps).
