[Tagging] How to put a name tag on an area with more than one type?

[Anders Torger]

Impressive work!

I had missed myself that the river flows through. To tie it together I 
would have made a multipolygon with two outers one on each side of the 
river, and I think I've already done that in some other wetland with the 
same issue. However that is not a fool-proof solution, as in some case 
you could have only bog on one side of the river and only marsh on the 
other, making it impossible to tie it together with a multipolygon.

The simple answer is that this naming concept is fundamentally broken, 
and that we need to have some other concept, such as fuzzy areas.

However I'll soon go through these edits again and then I will add 
multipolygon for the split, and if your renderer takes that into account 
we should end up with a single multipolygon. I think in the case of 
Muddus it will work in all cases, ie we won't hit the corner case 
described above which should be very rare. So I think this naming 
concept is okay as a stepping stone until we can move forward on this 
issue. I hope we can make a point though that this is not a acceptable 
as a long-term solution.

Your example also demonstrates the importance of having a reference 
renderer that actually renders correctly. I would not have discovered 
that I've forgot to tie the wetland together if it weren't for that your 
renderer actually implements the algorithm. A proper reference render 
gives better geodata, as it allows mappers to with their own eyes see 
what's correctly represented or not.
