They appear to have been resolved on IRC last night, 4 days before the

Australia, with much of its community already lost, to me appears to be a
voice in the wilderness.  The focus seems to be exclusively on meeting time
commitments decided by the OSMF board to delete the non-compliant data.
While I appreciate the need to have a line in the sand, there have only
been a couple of months where the tools have been available for remapping.
This has clearly been hugely insufficient in an area like Sydney, with
hundreds of thousands of ways, I'd estimate less than a quarter not
impacted by the licence change.

The non-compliant data will still be available through the API, but its not
clear to me how the client software will handle it or access it, or what
the point is in having it there.  The full history file contains deleted
data, but that file is very hard to manipulate, and getting back
information from prior surveys I'm finding near impossible.  The undelete
it data<http://cleanmap.poole.ch/?zoom=13&lat=-33.87314&lon=151.13641&layers=000B>,
doesn't reflect that in 99% of cases ways are trimmed and moved, not
deleted.

The planet file, diffs, etc will not contain any non-compliant data.

Australia will be completely flooded, as much of coastline is still
non-compliant.  There are very few areas of Australia that will be
untouched.  Sydney in particular is going to be completely decimated in
parts.  Sydney's south is probably the least affected relatively, but
entire swathes of the west, inner south and north are going to disappear.
Some of it is splits and remapping dating to the nearmap imagery era,
roundabout obsessions, and crappy imports, and hopefully there is still
stuff we can do post-transition to recover some information pre-dating it.
However, in honesty, many of those suburbs were comprehensively and well
surveyed in 07-08 by some people who have now declined the CTs.

The issue of the coastline has been discussed, but no-one that I have seen
has suggested a resolution to the issue.  I'm reluctant to divert time from
remapping tasks I see as more of a priority.

I've done considerable work to make large sections the Sydney waterways
compliant, I've also done quite a few individual Sydney suburbs to full
compliance, and now I'm working on all the Sydney trunk roads and
motorways, which I'll probably finish to a basic level before the 1st.  I'm
was hoping to do the same for at least all the regional cycleways, but I
know I won't get there in time.

I'm also trying to save any compliant information, like names, from objects
that were created by CT decliners.  In general, if a non-highway object was
created by a CT decliner and doesn't have any information added by a CT
agreer, I'm deleting it.  They just get in the way at this point.

The railways also seem to be coming along nicely, thanks to MapStar.  Many
station names are going to still go, though, but they should be easy enough
to fill in the aftermath.

I'm happy to cooperate with any more coordinated re-mapping exercise.
