[Talk-GB] Fences & Hedges

[Michael Collinson]

Yes, I do exactly as Brian does have in a personal project to map all 
the field boundaries in Upper Wharfedale.

IMHO the point of mapping the type of barrier is 1) character - give an 
impression of what an area is like in map form. Here it does not really 
matter whether each specific stretch is squeakily correct. 2) 
Navigation. So the most obvious; which is typically the hedge.

I'll also be cheeky and promote one more thing: Mapping from aerial 
imagery is normally needed to systematically map an area, at least to 
start. It is not always possible to distinguish so I have used the 
non-standard barrier=yes to to be safe. I think it would a useful addition.
