Lost road

General talk
1

Please look at this link:
http://www.openstreetmap.org/edit?lat=37.932677&lon=23.739165&zoom=18
And compare with the same area in ‘View’. You can see that a semicircular road is missing from ‘View’ while exists in ‘Edit’.
I add that road a couple of years before and was there until the last few days. I observe the absence yesterday and initially i thought that somebody remove it and add it again, so i wait for one day to appear in ‘View’ but that not happened while other changes that i make are visible in ‘View’.
So what is it? some kind of bug or what?

Hmm… strange. I can’t find any problems with that way. There has been nobody else editing this way than you (http://www.openstreetmap.org/browse/way/5191858/history). Even “keep right” couldn’t find an error: http://keepright.ipax.at/report_map.php?lat=37.93268&lon=23.73916&zoom=18&layers=B0T
If the street won’t show up in the next days, I’d suggest to open a ticket (http://wiki.openstreetmap.org/wiki/Mapnik#Bugs_and_rendering_suggestions).

There is something strange about the way.

http://www.openstreetmap.org/browse/way/5191858/history shows only 7 nodes in the latest version, but
http://www.openstreetmap.org/browse/way/5191858 shows 8 nodes, the difference being this node:
http://www.openstreetmap.org/browse/node/36231873 which joins one end to the adjacent street.

I’d be tempted to revert the way to an earlier state to see if that helps, and if it doesn’t perhaps delete it and redraw it.

Thank you all for the responses.
I can delete it and redraw it, it is not a big deal, but i post this message out of curiosity.

I’ve just looked at the XML of the way history and it looks like there was a problem writing the information from Potlatch while you were editing

Note the two updates showing as:
“2009-03-08T09:52:25+00:00”
The first has some double tags, and the second (the later) has no nodes. I believe this occurs when changes queued up for the server are delayed and more get queued up for the same way, and that the API 0.6 changesets will probably help resolve this.

The later changes look OK to me, but the way still doesn’t seem to have been rerendered. I’ll see if manually requesting a rerender of the correct tile helps, which I think was 2318,1580
