[Talk-GB] Definitive Paths Map Source

[martyn]

In Hertfordshire, East Herts publish maps that are drawn on top of an OS 
layer.  But for each parish, they also publish a text description of 
each numbered right of way, last updated in 2006.  Useful as not all 
real-world physical signs have the number.  So using that with the NPE 
layer in Potlatch it should be possible to check and reconstruct the 
present ROWs.

Anyone see any problems with this method?
