[Talk-GB] VectorMap District: Completely crazy idea, maybe, but...

The lack of public right of way information is disappointing - but it
is within OSM's capabilities to walk and map it. However, the lack of
field boundary information is a serious deficiency as these are
invaluable in practice to walkers attempting to plan, navigate, record
and publish walks - especially in the more lowland and more farmed
areas. Without the OS's right to enter onto private land without any
advance permission, OSM mappers will remain seriously hampered in any
attempt to map field boundaries. Hedges may be visible in good quality
satellite or aerial photography but fences (and especially electric
fences) will be very difficult.
Having said that, Nick's idea sounds good - probably "as good as it
gets" with the present availability of data. I don't have the relevant
IT skills but certainly support the concept!
