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.
