Re: [talk-au] Removing ABS data

Ben,

It appears that ABS data that is inland may connect to the coastline
but doesn't continue along it with the same way.

Therefore I'm pretty sure that if you are carefull not to actually click
on the coastline at all, then you will be quite safe.

Happy cleaning
Nick

 All good points, Nick.  Thanks.

Except for the childish dark side comments.

Nick, please accept that people have their reasons for declining the
CTs, just as you presumably have your reasons for accepting.

 Is it necessary to remove that data now, before the big change-over date?
   1. Is there not still a chance that people who have declined the new
 licence
  will change their minds, and accept?
   2. Surely there's some magic in the works, that is going to swiftly and
   completely remove the non-compliant data for us?

 Yes, I think it is necessary to delete this data now...

 Firstly, the importer of this data has moved over to the dark side and
 seems to be
 relishing in the possible data loss to the OSM project. So there isn't a
 chance in hell
 of him accepting the CT's.

 Even if he did, I'm not sure the ABS data would be allowed to be relicenced
 under Odbl.
 And even if it was, this data is woefully out of date and now almost
 useless anyway.

 Also the ABS data appear as red dots and lines in Fredricks tainted data
 display and
 this masks out other bad data that needs to be removed and either remapped
 or OSM mappers
 good data recovered from history - where available.

 Also the places where people have mixed the ABS data with otherwise good
 data need to be
 looked at individually, now, to try to save as much good data as possible.

All good points, Nick.  Thanks.

I guess I've been hoping that it doesn't come down to individually looking at
everything and manually fixing things... but it does (if we're to save as much
data as possible) and so I'm quite happy to get cracking with it...

:-)

I'm particularly worried about large slabs of coastline disappearing.


Ben,

I'm avoiding touching the coastline since it does not get in my way for
remapping roads and since I don't want
to flood all of australia :-).

I'll have a pretend delete session of ABS ways near coastlines tonight to
see if it is easy to avoid the
coastline. If not we'll have to split the way near the coast to isolate it
from the coast before deleting it.

I know for a fact that Frederick would love to be the one to finally get
rid of that coastline and put a
previous clean version in its place (which we could then improve from
imagery over time).

What I'm doing is deleting all the unedited ABS data (author is still
ABS_2006) from an area which I will soon
be cleaning. Then I wait for the OSM_inspector to remove their red
dots/lines then I'm ready to work on that
area.
Any boundary data left in the area I try to recover clean tags from
acceptors history and remap from imagery
if available.  If I can't then I just leave it for others or for the April
rinse down.

Cheers
Nick

PS don't worry about the broken boundary multipoligon relations, they can
be removed holus-bolus any time later.
