Recently, I wanted to fix a few local islands and public parks in
coastal Maine, where I have local knowledge. But much to my dismay,
the local area was pretty thoroughly broken:
* The county lines along the coast are based on a really old (and
incorrect) data set.
* There's some confusion between towns (admin_level=8) and sub-town
boundaries (admin_level=?).
* Most towns are marked with nothing more than GNIS points.
As a result, the local maps are incorrect, ugly (thanks to the bad
county lines everywhere) and incompatible with Nominatim.
I've prepared a more detailed explanation of what's wrong, with
pictures, examples, and a couple of possible ways to improve things:

Personally, I'd be interested in tackling 4 small towns and maybe the
Lincoln county boundary. But it looks like a large portion of the
Maine coast suffers from similar problems. If anybody feels qualified
to address the larger problems, I'd be grateful—and happy to help out.
Thank you for your feedback and suggestions!
you can get 2014 boundary data for Maine from TIGER and it should be
pretty good.
i have some extracts from it in GeoJSON in github if you want to look it
over.
Maine GIS has data online but their current licensing is extremely
incompatible with
the ODbL
