Field boundaries can be traced from Bing? A lot of work though.
Contours can be done using the same method as Cycle Map.<br>

I don't buy the (implied) 'we paid for it so it should be free to
use' argument by the way.<br>

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Wales) even though inevitably out-of-date (and the poor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.<br>
