Hi,
Looking at Tanzania relation on OSM, I see that it has several subarea linking to Zones - like Northern Zone. Looking at wikipedia, the first administrative subdivision seems to be 22 Regions, not 7 Zones.
So, here is the question: are these seven Tanzanian Zones official?
For a bit of context: I need stable OSM relations to generate smaller extracts for Osmose QA, as Tanzania is getting a bit too big now.
Thanks,
Jocelyn
