Ok, great to know this, tx I didn't realise.  ID also doesn't seem to
validate as the original buildings (parts of) where still there it seems.

Indeed, I think the biggest problem is realising there is a better
source and also skills to understand that some sat photo's aren't
looking at the earth in a 90 degree angle.  I'm sure you'll find houses
like that from my hand as well before AGIV came along.

I pretty much completed all I could, the remaining issues are usually
borderline problems, only a few mistakes or a place where the node is
way off (usually centralised in the middle of the property) but where
the house is way off.  I never use the meters option in the tool, I keep
the default behavior there.

But like this person made a second changeset where he popped number 110
into a row clearly in the 80's.  It's way off, he mentions the source
which is the website of Century 21 and funny enough, that site has got
the number wrong, hence they introduce errors.

I wish there was a way to let a mapper know the area has been
housenumbered against trusty sources.
