At least as far as I can see it's the trend to avoid "left:*" and "right:*" and rather have a relation for the entity inside. At least that's what http://wiki.openstreetmap.org/wiki/Relation:boundary suggests. > My plan: > 1. I have merged corine data with of the maaamet shoreline (taken from the > same admin info).

At least it doesn't match with international standards. At least up to admin_level=6 I'd rather use borders which include multiple islands ... otherwise the rendering looks awful. BTW: Lately I have added "official" Estonian maritime border to OSM ... so we should use it. :) > 6. tag new shoreline properly What do you mean by that? That's the rather simple part. > 7.

What about densely mapped areas (many nodes -> limit)? Which version of the script are you currently using? Andre -- Mieser Charakter, mieser Verlierer.
