[OSM-talk] [OSM-dev] Polygons and Multipolygons

Hi,

True. What we had been looking for was a term for "polygons with  
holes"; it seemed unreasonable to create a relation "type=polygon" as  
plain polygons, without holes, don't require relations. But  
multipolygon is somewhat of a misnomer.

There are only 2788 in the database so it would not be too hard to  
change. I wanted to automatically add the "inner" and "outer" flags  
to the existing polygons anyway, although they're not strictly  
required they would make processing easier for some.

Bye
Frederik
