Hello Susanna,
1. On commons, neither NordNordWest (one of the best and leading DE
cartographer) nor Bourrichon (one of the best and leading FR cartographer)
used any machine-readable template for their recent GIS maps.[1][2][3] The
best they do is to use {location} to state the center of the maps. The
North, South, East, West borders and stretching are hard coded without
template.
This is indeed something needing change.
2. On local wikipedias, there are {location map COUNTRYNAME} templates to
display GIS maps which store these very same values in a machine-readable
way[4:wp] while the commons page have them hard coded[3:commons].
So technically, we may mass import these GIS based maps to a georeferenced
system.
