Once it's been aligned against a few GPS traces, yes. Until that's been
done a wall mapped just from Bing imagery might be a few meters out.
However, even if a wall is mapped a few meters wrong, the position
relative to other features will still be useful - although once GPS
traces are added it'll need to be realigned, of course.
Cheers,
Andy
