Hi,<br>
<br>
My guess is that advanced reverters are likely to be found on the
Dev list.<br>
<br>
Best wishes,<br>

Dear some-advanced-user-of-revert-scripts(?) -- or otherwise an
advanced reverter...
<div><br>
</div>
<div><b>Long story short: </b></div>
<div>I introduced <a moz-do-not-send="true"
href="http://www.openstreetmap.org/user/ALCE%20SamuelPaul">Samuel</a>
to fixing OSM data in Haiti and the whole Hispanola before the
license change bot runs over us. All things well in Haiti and in
Dominican Republic and he and we together have saved a lot of
roads... That is, all well until yesterday...</div>
<div>He ran into some memory problems with JOSM and (without going
into details) while trying to sort it out seems to have ended up
accidentally moving 30+ thousand nodes a tad over 8 meters +
applying inadvertently odbl=clean tag to a hundred or so
roads. ... And uploading these to the server, of course (in two
changesets). All this in the Santo Domingo area in DR=DO.</div>
<div><br>
</div>
<div><b>To the point:</b></div>
<div><b>Is there anyone who could try to revert these accidentally
messed up data = uploaded changesets?</b> .. It seems that the
only(?) solution would be to try to use the Perl Scripts that
Frederick Ramm has created -- but you possible advanced reverters
would already know this -- or know of possible better tools.</div>
<div><br>
</div>
<div>The changesets are <a moz-do-not-send="true"
href="http://www.openstreetmap.org/browse/changeset/12187570">http://www.openstreetmap.org/browse/changeset/12187570</a>
& <a moz-do-not-send="true"
href="http://www.openstreetmap.org/browse/changeset/12187477">http://www.openstreetmap.org/browse/changeset/12187477</a>
and it would be best to revert them completely.</div>
<div><br>
</div>
<div><b>Few problems articulated and background opened:</b></div>
<div>* Earlier attempts to revert:</div>
<div>I and Severin tried to revert these changesets yesterday as
soon as I heard of the problem. Didn't succeed as it seems that
the Reverter plugin of JOSM doesn't work with the new API.</div>
<div>I seeked help today from #OSM IRC and Daeron tried to revert
these (or actually just the latter 12187570) with Frederik's <a
moz-do-not-send="true"
href="http://wiki.openstreetmap.org/wiki/Revert_scripts">revert
scripts</a> but ran into dirty revert problem(s?) if I
understood correct.</div>
<div><br>
</div>
<div>* About the problem(s)</div>
<div>We first thought that the problem was only the addition of
odbl=clean tags en-masse. However, upon my detailed examination
this hadn't happened as Samuel thought it had.</div>
<div>I discovered however that there seems to be a consistent
8.13/8.38m move of all(?) of the nodes. .. Which technically has
shifted only the nodes -- but as there are over 30k of them
spanning most of Santo Domingo it means that practically
everything in the capital has shifted this 8+ meters. .. And this
is the reason that it seems to me that a revert would be the only
way to fix this properly.</div>
<div><br>
</div>
<div>* Dirty revert parts:</div>
<div>As far as I can see there are only three possible dirty reverts
causing changesets (currently):</div>
<div>1) My attempt to fix the problem: <a moz-do-not-send="true"
href="http://www.openstreetmap.org/browse/changeset/12222867">http://www.openstreetmap.org/browse/changeset/12222867</a></div>
<div>2) My fixing of another problem in the area: <a
moz-do-not-send="true"
href="http://www.openstreetmap.org/browse/changeset/12222818">http://www.openstreetmap.org/browse/changeset/12222818</a>
- I don't see how this would collide with the problematic
changesets but maybe it's better just to nuke this too -- it would
be very easy for me to redo what I did here. </div>
<div>3) a small changeset <a moz-do-not-send="true"
href="http://www.openstreetmap.org/browse/changeset/12207601">http://www.openstreetmap.org/browse/changeset/12207601</a> that
only has 4 nodes and 1 way with version >1 (visible on the top
of the lists).</div>
<div><br>
</div>
<div>I would be super-relieved if someone could figure out how to
revert these -- and would certainly take additional steps in
trying to see that this will not happen again (such as adding more
memory to all of the JOSM instances of our local mappers and going
through uploading procedures in case = when in any trouble like
JOSM memory or connection problems -- especially when dealing with
large chunks of data).</div>
<div><br>
</div>
<div>Needless to say that we will not touch the area until we either
hear that someone has reverted all needed changesets / edits
succesfully, adviced on how to try to use the scripts, or given a
definitive that it's not possible in which case we'd move into
figuring out solving this manually. (.. There's luckily decent
amount of GPS traces in/from/of the area.)</div>
<div><br>
</div>
<div>Also, if you know of some reverter-wiz, please don't hesitate
to pass on the request. .. And maybe it's a good idea that whoever
would (hopefully) take a crack at this would announce it here to
avoid further trouble..</div>
<div><br>
</div>
<div>Sorry for the mess from my part and crossing my fingers &
optimistically thankful in advance,</div>
