[Talk-GB] This one is driving me potty

[Gregory Williams]

I've managed to remove the kink from the road with this changeset:

 

http://www.openstreetmap.org/browse/changeset/13247989

 

I loaded the data in JOSM and showed the Mapnik rendering as the background.
I then checked the history of the nodes near to the kink and found that the
then penultimate location of node 31790851 was at the point of the old kink
in the road that was still being rendered. Deleting that node from the road,
which to my eye doesn't really alter its geometry visually, has fixed the
issue.

 

I guess that for some reason or another the previous version of the node, or
at least the line geometry for the road which used it, was still stored in
the backing Postgres database used for rendering. Hence it was being
rendered based upon stale data.

Delete and redraw? I've tweaked it slightly and some things have
re-rendered. But it is a bit odd.

I'd be very grateful.

 

The data within OpenStreetMap appears correct, and had been correct for
several months. The map used on the OpenStreetMap main page to display the
data is not updating (redrawing) to show the changes.
Not sure why this is happening because this map (mapnik) usually updates
very quickly.

I guess someone else might be able to answer why the map is out-of-date.
