[OSM-dev] Multipolygons as members of a multipolygon

[Paul Norman]

I don’t believe anything supports nested multipolygons and I haven’t seen any in the database. As I read it, that page is only intended to apply to route relations.

 

Personally, I’d regard any multipolygons containing non-ways as being in error.

JOSM relation editor supports parent and child relations.

 

Thanks for the link. I have to admit the text is not an easy read, and it doesn't mention multipolygons in the context of super-relations.

For now, I'll assume the mentioned relationship just means "is within", without any additional geometric implications (like holes etc). In order words, I'll ignore it ;)
