WTile terrain for 15 West to 15 East. So one of the principles of these terrain grids is that tiles and tile sides should be specified according to objective geographical criteria, not political considerations. So hex 4CG0 140, 512 should not be a sea hex as the majority of the hex is covered by land and we do not want the narrowest gap from England to France to be a whole hex. Given that it is a land hex by geoprhical area it must be assigned to France
