[Talk-ko] South Korea top-level admin boundary creation complete

[Andrew Errington]

Hi Wesley,

Good work.

I haven't checked, but have you been making the boundaries using
relations, so that you can re-use common segments of the boundaries?

I agree with your choice of admin_level for -do.  I thought about this
carefully a while ago, and I have been waiting for a chance to discuss
it.  Here are my conclusions.

Admin levels:

1	N/A
2	National border (South Korea coastline and 38th parallel)
3	N/A
4	Province (-do), Metropolitan City (gwangyeok-si), Special City
(Seoul) (teukbyeol-si), Special Self-governing Province (Jeju)
(teukbyeol-jachido)
5	N/A
6	County (-gun), City (-si) or District (-gu)
7	N/A
8	Township (-myeon), Town (-eup), Neighbourhood (-dong)
9	N/A
10	Village (-ri), -tong or -ga

If you agree (or rather, if there is no disagreement for anyone) I
would be happy to edit the wiki and add an entry for Korea to the
list.

For classifying the size of places I came up with this:
Place (defined in Wiki)	Korean place (suggestion)
	
city 	100,000+ 		-si (including gwangyeok-si and teukbyeol-si)

town 	10,000 - 100,000 		-myeon -eup -dong

village 	<10,000 		-ri -tong -ga


Finally, do we need a district node if we have a district boundary?
The district node can be calculated as a centroid of the boundary.  I
think that's what the map renderer does when it places the label for a
region.

Best wishes,

Andrew
