but are traces really that important now? They have some uses but
the bulk of sources now and going forward are from other methods?

If "other methods" means "copying from other data sources rather
than actually going out and surveying" then you're never going to
get "the best map", only "a map that is in some areas almost as good
as some others".<br>
<br>
For example, yesterday I was here:<br>
<a href="http://www.openstreetmap.org/#map=15/53.2346/-0.3269"><br>
http://www.openstreetmap.org/#map=15/53.2346/-0.3269</a><br>
<br>
Without going there you'd be able to guess at the exent of the
woodland (depending on the age of the Bing imagery) and you'd think
(based on what OS OpenData says) that it's called "Stanfield Wood".<br>
<br>
If you go and have a look you can see the correct name ("Stainfield
Wood" - which matches the village to the north), who runs it, and
the fact that it's not open to the public. The actual GPS trace is
useful for helping to spot places where Bing is offset from reality
(although here in flat Lincolnshire it's only a 4-5m at a guess).<br>
