do you think that you can update the data before we enter to the read only

Actually, in might be pretty simple in the first case. To the best of my

hate_osm_nitpickers) is known for mass downloading, erasing and
re-uploading the unmodified data under his name. In his case dropping all
his changesets in the area might be the solution.

My jxapi instance is lagged behind - it lost its state.txt file in a crash
and fell a couple days behind. Not knowing the age of the data, my
generation script refused to generate, as intended. My upload script ignored
the return code and tried to upload anyways, not as intended.

Also, a bug in cleanway was found. Cleanway ignores tags and queries WTFE
which does not consider odbl=clean, so cleanway does not consider
odbl=clean. I can fix this, but need to write some code.

Subject: [OSM-talk] ODbL-clean Coastlines



I have been running a nightly coastline generation on my server, using the
latest data from my jxapi server. Tonight I switched it over to filter out
data that WTFE reports as dirty. This is somewhat more aggressive than the
rebuild will be, but the results are worrisome.

A PNG showing the OSM coastline post-transition along with red dots for
where the coastcheck program found errors is at
http://maps.paulnorman.ca/coastlines24b.png
The red dots represent places where coastcheck found an error

A few things can be seen:
No continent will generate a satisfactory rendering. Australia, the US, 
most

of Africa and most of Eurasia from 50 degrees south will be completely
flooded.


Paul
thanks a lot for generating this, the situation is far worse than I had 
thought it was going to be.




There are 3471 points where coastcheck found errors. Normally I would 
expect

about 10.

The following areas are particularly bad:
The west coast of the US
The US coast of the Great Lakes
Australia
Antarctica (which has significant parts completely missing with no error
points since there's nothing left to even try to close)

When examining the data, I found most of the ODbL-dirty status was mainly
from the following accounts:
hasse_osm_korinthenkacker (Antarctica)
Kin (Antarctica)
Blars (US West coast)

I see a few ways for dealing with the coastlines:
- Remapping. Obviously this is the only option where the coastline was
actually created by the non-acceptor.


One advantage of remapping is the possibility that there are now better data 
sets available for import than the PGS data which was originally used.  I'm 
particularly thinking here of the US  Canada.



- Adopting changesets. Many of the dirty ways and nodes appear to be
imported. If the imported just imported PD data than they have no IP in 
the

ways and they can be retained.


Are you saying that it is impossible for data originally derived from PD to 
ever have IP in it, no matter what else is subsequently done to it?



- odbl=clean. It's generally easy to verify that a way is a coastline from
imagery



There is I think one other option.  Since a pretty much error free 
processed_p.shp file will be available just up to the licence switch over, 
then is it not legally possible to continue use this file in Mapnik combined 
with post switch over OSM data to create the maps.  The missing coastline in 
OSM can then be re-mapped on a more leisurely basis.


David


My coastline files are available in the usual location of
http://pnorman.dev.openstreetmap.org/coastlines/ but are named 
coastlinec_p
and processedc_p. processedc_p has not yet uploaded but will be complete 
in

about an hour.

Additional detail of some regions can be found at
http://maps.paulnorman.ca/coastlines-europe.png
http://maps.paulnorman.ca/coastlines-na-lakes.png
http://maps.paulnorman.ca/coastlines-na-west.png
http://maps.paulnorman.ca/coastlines-nz.png
http://maps.paulnorman.ca/coastlines-au.png

If opening processedc_p in QGIS be sure to make a spatial index or it will
crawl.

A refresher on coastlines for those who haven't tagged them in awhile:

Direction *matters*. Land on the left, water on the right.

Each end of each way should join with exactly one other natural=coastline
way

I am not sure when each processedc_p file will be completed. Cron starts 
the
job at 5 AM PST and I'd expect it to take about 5 hours, mainly depending 
on
WTFE server speed and my upload speed to errol. The coastlinec_p files 
will

be uploaded first so arrive at the server earlier.

Technical details:
The results of the jxapi way[natural=coastline] is filtered by cleanway to
remove any objects reported as severity=normal, leaving behind 0 or 1 node
ways if necessary. It then is passed to the coastcheck programs and the
results uploaded.

A CT-clean way to which a decliner added a tag other than 
natural=coastline

would be removed by this algorithm, but not by the rebuild.

I was just going to suggest this, while it limits you to  CC_by-SA 2.0
as a licence for tiles (or similar), there is no reason that you
couldn't use a pre-licence change coastline for rendering (in the case
of the main OSM site, the tiles are going to remain CC-by-SA 2.0 anyway).

I guess there are at least two problems.

Firstly the PGS import script had a simplification factor variable, which 
the person running the import could change.  I know that prior to doing my 
imports I played around with a number of different values for this 
variable to strike what I thought  was an acceptable trade off between 
number of nodes created, and the complexity of the resulting ways. 
Therefore what was uploaded to OSM was not simply PGS data, but was PGS data 
as amended by my decision making process.  I guess you would have to know if 
the user who did the imports in question made any similar changes.


Secondly you could use the PGS import script in two ways.  Either (i) run 
the script against the PGS data and let the script directly upload to OSM ; 
or (ii)  use script to create an OSM file, which could then be edited in 
JOSM, and then use JOSM to upload the data.  If choosing method (ii) you 
were then able to look at the data in JOSM and make corrections to it before 
uploading to OSM.  Although when doing my imports I started using (i) I 
later switched to method (ii) because that way what I uploaded to OSM was 
more error free. Had I now been a CT decliner I see no legal difference 
between the resulting data in this instance and data which If it was 
subsequently edited by a decliner, well, that's different.

They are not anonymous. You just can't see their nickname.
If they log in and agree to the contributor terms their edits will be

Here is a list of changesets of agreeing users still listed as anonymous

Copyright applies when you author something, regardless of if you state your
name on it. As OSMF is the party wanting to do something not allowed by the
(implied) license of the contributer, they have to seek permission. If the
copyright holder decides not to reply, OSMF doesn't have permission to

You think that OSMF could claim that distributing contributions that it

could be fair use?

Also remember that these people are not anonymous to the OSMF. They've got
registration information on them just like they do on every other user. It's

thought you were distributing under fair use, you delete the offending
data, and life goes on. In other words, the worst a lawsuit is going
to cost the OSMF is THE HARM IT'S VOLUNTARILY DOING TO ITSELF.



Your worse case sounds so harmless.  Of course it's possible to sketch an 
alternative worse case scenario:


At some time in the future after being asked to delete the offending data, 
the data is deleted and ... ...


a) all those contributors who had  made edits to that data after 1 April 
2012 get very annoyed because they see the results of their work deleted., 
and when they query this they are told hey, its a risk we thought we'd 
take, and by the way we may have to delete a load more data in the future, 
so be careful what bits of OSM you edit.


b) users of OSM data get very annoyed because having seen masses of data 
disappear once, they suddenly see masses of data disappear again, and when 
they query this they are told hey, its a risk we thought we'd take, and by 
the way we may have to delete a load more data in the future, so be careful 
which bits of OSM data you use.

  The argument hey,  we understand we don't know if we have any right to use 
  this data, buts lets leave it in and hope no one complains doesn't sound a 
  particularly moral one to me.  It also seems to set a rather dangerous 
  precedent.

Copyright isn't property. It's a bargain. We agree not to copy a work
for a period of time, unless the copying is not for profit, is
educational, is limited in quantity and/or a number of other nuances
that don't fit into not particularly moral.

You are describing the current case, more or less. We had to kill OSM
to save it. We already are finding that swathes of data are
contaminated and will be deleted, e.g. most of the west coast of the
U.S. and most of the Great Lakes, which also means going up a fair
ways into the continent because the larger rivers are considered
coastline. That was a gotcha for me. The Racquette, the Grass, and the
Oswegatchie were all going to be deleted because they were coastline,
public domain data imported by a user we cannot ask to sign onto the
CT, but who supposedly might sue us even though they can't even be
bothered to decline. I'm FINE with preserving the anonymity, and I'm
even FINE with allowing anonymous users to decline.

I'm NOT FINE with allowing unnamed people to hold a copyright without
bothering to decline. There's a REASON why copyright notices have to
contain the name of the copyright holder.

This situation has just gotten ridiculous. The OSMF is saying that it
cannot use:

  o public domain data,
  o which may have been edited, but which shows no signs of having been,
  o which has been modified until it is not recognizable as the original.
  o imported by a user whom nobody can contact,
  o who has not bothered to decline acceptance of the OdBL,
  o a license nearly identical to the existing license.

And people are trying to defend this, against all logic, because they
think copyright is inviolate, and that judges are just computers,
executing the law as if their JUDGEment cannot come into play.
