[Talk-blr] admin-level для relation и way

[Aleś Bułojčyk]

Вітаю !

Думаў трохі пазьней пісаць, але сапраўды тут праблема.

На сёньня для абласных цэнтраў створаныя межы як relation з
type=boundary,boundary=administrative і з цэнтрам з роляй admin_center.
А для малых гарадоў і вёсак - relation з type=multipolygon і з цэнтрам з
роляй center. Калі мяжа пазначана way - тэгі такія самыя як для цэнтра.

Нешта надта дзіўна выглядае. Трэба было б неяк сыстэматызаваць.

WBR, Alex.
