Re: [Maposmatic-dev] Problem with german city borders

Hello,

Thanks for bringing this issue to the list. We definitely need to find
a solution to this problem, so that all German cities can be rendered.

For example, Berlin is a Länder, so it has an administrative boundary
of level 4. But Berlin is also a city, so why doesn't it have an
administrative boundary of 8 ?

In France, Paris is both a departement (level 6) and a city (level 8).
Both administrative boundaries exist, because Paris exists at both
administrative level.

See:
 http://nominatim.openstreetmap.org/details.php?place_id=49962699 for
 the level 6 boundary of Paris (departement level)
 http://nominatim.openstreetmap.org/details.php?place_id=49949948 for
 the level 8 boundary of Paris (departement level)

IMO, since Berlin is both a city and a Länder, it should also have
several administrative boundaries of different levels, even if
geographicaly, the boundaries are the same.

What do you mean by "city landuse nodes" ?
