Field boundaries can be traced from Bing? A lot of work though. Contours
can be done using the same method as Cycle Map.
I don't buy the (implied) 'we paid for it so it should be free to use'
argument by the way.

Although the OS has at last been forced into releasing some data we
have paid for, it is still withholding field boundaries (as per OS
1:25k). These are invaluable for footpath walkers in agricultural
areas (i.e. most of England and parts of Scotland and Wales) even
though inevitably out-of-date (and the poor registration between the
rights of way GIS layer and the base mapping can all too often leave
you backtracking after walking a few hundred metres on the wrong side
of the hedge!). Clearly most boundaries cannot readily be surveyed on
the ground by OSM workers (short of triangulation) although satellite
mapping is a big help where licence-free and clear enough. (Nick and
others - thanks for the great work). Sadly I still cannot really use
OSM for footpath walking away from conurbations. On a smart phone the
zoom limitations make the OS 1:25k mapping of limited use (although
Multimaps' OS version is better). Google satellite mapping is often
too dark to read out of doors (and tiles cannot be downloaded for
outdoor use because of Google's "fair usage" terms - as I have learned
the hard way after having my IP address blocked by Google for 24
hours!); Google Maps is of little use out of town. What is needed in
OSM for walkers - but how to do it? (thanks to Nick and others for
great work) is (a) contours and (b) field boundaries.
