<div class="moz-cite-prefix">I should re-phrase my comment, GPS
traces are important, but for small niche parts of the map or
brand new developments. I do use GPS, but the bulk of editing is
done from other sources, and I don't mean Bing, there are loads of
sources coming online every day.<br>
<br>
In Worcestershire, where the local council make available a TMS
service of the public rights of way and add to that overhead
imagery to confirm where people are actually walking across a
field and I've mapped a huge percentage of the PRoW around here
without leaving home. Yes some bits need an onsite verification
but the bulk is armchair.<br>
<br>
I'm not ashamed of armchair mapping and all power to those who
have the time and resources to go and survey on foot but the vast
percentage of my mapping time is spent online. If I do ground
survey it's when I'm somewhere for work.<br>

but are traces really that important now? They have some uses

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 moz-do-not-send="true"
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>
<br>
