Perhaps @dmeaux @qleroy or @tarraschk might have some insights here, as they've worked more closely with the French maps than I have :)

Hey @rusackas I'm okay to have a look and fix this in the data generation if you want. Just assign me to the issue if that's okay. Should be able to do that this week-end.
