My suggested solution:
Create a brand new collection of nodes with the position of "all 
fantom nodes", and sending'them to the Tech tem of OSM. They'll be 
able to run a query into the
'OldNode' and 'OldWay' tables and switch the "visible" status from 
'true' to 'false'.


Don't do this. The rendering database doesn't have OldNode or OldWay 
tables or a visible status. For that matter, the master apidb database 
doesn't have those tables either, it has ways and currentways tables.


This is normally where I'd give a solution, but I don't have one. It's 
an osm2pgsql bug, not a DB bug, but without a reproducible testcase and 
verification that the bug happens on recent versions, it becomes a 
significant effort to get anywhere.

The tile's rendering seems to be OK : I'v addes some items (trees) and they
appear on tiles.

I've also created ans deleted one driveway and the regeneration of new tile
keeps the "fantom driveway" anyway.

Any others ideas/suggestions?

The techs seem to have too many tiles to revise.  I dirtied the tile (addding 
suffix /dirty) and not corrected 
yet.http://c.tile.openstreetmap.org/19/174624/186164.png

Hello,
      I have done extensive editing with Potlatch2 for the Cape Breton 
University campus in Sydney, NS.  My son is a student at CBU and I have visited 
the campus several times.  The Bing imagery appears to be fairly recent and 
good quality.  The edits were completed more than one week ago, maybe two weeks 
but some of the map tiles still don't appear to match the vector data.  Here 
are some examples: * Shannon School of Business building - it should be 
rectangular - http://www.openstreetmap.org/#map=19/46.16997/-60.09532 * 
Technology Centre building - shape does not match Potlatch2 vectors - 
http://www.openstreetmap.org/#map=19/46.17119/-60.09294 * Library building - 
there appears to be extra lines that could be ghosts of the previous vectors - 
http://www.openstreetmap.org/#map=19/46.17009/-60.09120
      99% of the edits I made in this area are reflected in the OpenStreetMap 
tiles but the above items are a few examples where the map tiles do not match 
the vectors that I can see with Potlatch 2.  I am certain I have waited long 
enough for the OSM servers to update the tiles.  Does anybody have an idea why 
the tiles do not match the vectors?

Thanks,Bernie.--

[Talk-ca] Map rendering errors

2015-10-30 Thread Bernie Connors 
Hello,

  I have done extensive editing with Potlatch2 for the Cape Breton
University campus in Sydney, NS.  My son is a student at CBU and I have
visited the campus several times.  The Bing imagery appears to be fairly
recent and good quality.  The edits were completed more than one week ago,
maybe two weeks but some of the map tiles still don't appear to match the
vector data.  Here are some examples:
 * Shannon School of Business building - it should be rectangular -
http://www.openstreetmap.org/#map=19/46.16997/-60.09532
 * Technology Centre building - shape does not match Potlatch2 vectors -
http://www.openstreetmap.org/#map=19/46.17119/-60.09294
 * Library building - there appears to be extra lines that could be ghosts
of the previous vectors -
http://www.openstreetmap.org/#map=19/46.17009/-60.09120

  99% of the edits I made in this area are reflected in the
OpenStreetMap tiles but the above items are a few examples where the map
tiles do not match the vectors that I can see with Potlatch 2.  I am
certain I have waited long enough for the OSM servers to update the tiles.
Does anybody have an idea why the tiles do not match the vectors?

Thanks,
Bernie.
