Several of us on this list plan trips by blank areas on OSM and
non-blank areas on other maps, what we currently lack is a good
way/method to store information about non-existent roads.

In Qld this is somewhat simpler since we have access to property
boundaries and we can simply mark non-existent roads as non-existent
and line them up with the gaps between properties, however we can't
use this method any where else yet.

I've penned a few thoughts on what to do about this on the wiki, but
they all seem to be lacking for various reasons.

But yes, knowing the difference between non-existent and non-mapped is
very helpful, just ask Liz :)
