Field boundaries can be traced in this way, with the caveat that 10 
years can be long time in terms of field boundaries (certainly what I've 
seen of the Bing data locally seems to derives from getmapping's 
"Millennium Map" and dates to the early 2000s.  Still often better than 
the OS though...

I've certainly used Bing to fill in field boundaries locally, based 
mostly on what I can see from footpaths and roads.  The sun angle of the 
coverage locally is quite low enabling you to tell hedges and fences 
apart in 90% of cases.

Cheers,
Andy
