Desperation with dumb tracers

Posted by daveemtb on 23 May 2009 in English (English)

Argh! After putting this junction right twice I've had to take desperate measures. (see map location and click edit)

I wish yahoo tracers wouldn't assume that other mappers are wrong when they haven't been to a location recently themselves. This roundabout was changed to a big crossroads more than a year ago!

Grrrr!

Location: Llandough, Dinas Powys, Vale of Glamorgan, Wales, CF64, United Kingdom

Perhaps you could try adding note=Yahoo! is out of date here. or something like that.

Have you let the users know? h in potlatch to find who did it!

I guess you'd have to be blind to change it back again now! But there must be plenty of places where Yahoo is now out of date. I can think of several. In addition, I can also think of areas where GPX traces are now out of date.

Some way of removing out of date GPX points would be good. Could be tricky to implement though.

I've also noticed that your junction has a set of unconnected nodes at the northernmost highway=traffic_signals node. Can I assume that these should be merged?

I had put an explanatory note on all the nodes the first time I mapped it correctly! Hence the rather silly writing all over it now!

I think the uncorrected nodes were an error in Potlatch when I reverted the ways. They need deleting.

Perhaps it would be cleaner to draw a small bounding box with a note explaining that Yahoo!'s imagery is out-of-date here. Much like http://www.openstreetmap.org/browse/way/32737099 only in reverse...

I'm sure it would be neater, but people weren't reading the annotations on the nodes of the junction. I'll clean it up eventually, but thought more unmissable "hint" would be useful effective the short term to discourage reversion.

I should add that my initial exasperated diary post was not a complaint at anyone who does Yahoo tracing - I do quite a lot myself. It's just important that people don't assume it's right and the existing mapping is wrong.
