Hi Brian,
Yes, I would especially second Jerry's good comments in the previous
discussion thread he started about sticking to a "strict" definition of
heath as being characterized by species of the Ericacea
(http://gis.19327.n8.nabble.com/natural-heath-td5888994.html). This is
also a quite common definition for heath on topographic maps in other
countries, e.g. here in the Netherlands where I live.

Hi everyone
Looks like a challenge. We have discussed this before and there were
lots of very thoughtful and knowledgeable opinions, but no decisions
on any actions. I kind of got the consensus that many were
uncomfortable with the spread of heathland landuse data but we never
decided to do anything about it. It would be great in my opinion if
we moved on as a community and actually decided to act on our discussions.
Regards
Brian

Hi David,
I know the opinions about the need to create multipolygons are as
diverse as there are political opinions. It was just one example
where these features cause issues. My main question is simply if
there are any plans or ideas by the British community of how to
deal with these features, or if there is any consensus whether
they are desired or not. If not, would the community oppose
someone else removing them?

That' a problem with the renderers. Multipolygons are difficult for
both (human) editors and (machine) renderers, so only be used where
strictly necessary.
