Hi Ian,

I have been maintaining the national seashore boundary on cape code
using the new MassGIS parcel layer. The national seashore boundary in
OSM is now more accurate than the official park boundary available
from the NPS. It is simply incorrect to say nobody is maintaining
these boundaries because they can't be improved after they have been
imported to OSM.

I don't see how this is any different than the national park
boundaries. We have established tags: boundary=protected_area with
14,000 instances, and boundary=national_park with 8,000 instances. We
render items with way less instances than these two tags.

Seems to me like this is already a settled issue.

Dan, if you wan to import those ~10 shapes, follow the import process.
Make a wiki project page, talk to the people that use OSM for marine
stuff to make sure the tags are correct, simplify, JOSM validate, post
OSM files for review before you upload, etc, etc, etc, etc, etc....

Also, you might want to look at some stuff I have written about imports.
