Punish, as far as I know they've done the elevation terrain mesh from the N. Sea to the Swiss border, but so far we've only seen detailed areas from around Verdun to Metz and part of the Somme.
This is just speculation on my part then, but I'd expect the areas for the squadron missions/campaigns to have received the most attention concerning actual building landmarks and such.
We'll have to wait and see on what kind of ground work they've laid.
