Is it possible to use this in a infobox?
Topic on Help talk:Extension:Kartographer
We use it in https://el.wikipedia.org/wiki/Πρότυπο:Πληροφορίες_κτιρίου with coords from Wikidata.
How about in infobox road?
Yes, just use the frameless
option in the mapframe tag. It can also be done with templates/modules, like w:en:Template:Infobox mapframe.
Look:
{{Infobox road |name=Calabarzon road network |TAG HERE</nowiki>=<mapframe frameless text="Map of the Calabazon Region" width=500 height=500 zoom=8 latitude=14.1 longitude=121.5></mapframe> |country=PHL }}
On enwiki, there's a discussion and examples at w:en:Template talk:Infobox road#Mapframe_maps
