[OSM-talk] Ghost water rendering in mapnik & Leaky titles in osmarender

[Andrew Sawyer]

I have run into a problem (that can be observed in osmarender) with two
tiles found here:
http://www.openstreetmap.org/?lat=43.1289&lon=-70.7753&zoom=12&layers=0B00FTF

Mapnik appears to be rendering the old coastline data, dispite the fact that
there is no continuous way for the Piscataqua River (which runs from the
Atlantic Ocean between the Maine/NH borders) found in JOSM or Potlatch.

A little bit of the history of this area was that the tidal river used to be
tagged as a natural=coastline then I uploaded new data with
waterway=riverbank.  I caused some issues with the data, but ended up
cleaning the area up.  Unfortunately, there is still what appears to be two
tile leaks of water.  I isolated the area with the other waterways and can
not locate any ways/nodes that would be contributing to this error.

Is there some issue with the servers or the fact that it used to be a
coastline for why the waterway is still showing up? Could someone address
the apparent ghost data so I can go ahead and repair the current waterways,
so that they are rendered with the new data I replaced the old with (before
deleting to find the problem with the leaking titles).

Or is this a matter that is solely on the rendering side and nothing to do
with OSM?

Sincerely,

Andrew S. Sawyer
