[Talk-us-massachusetts] Fwd: Target Traill

[Lars Ahlzen]

I looked at some of this a few years ago when mapping Cranberry Pond 
conservation land and the Holbrook State Forest on the south shore, 
around here: http://osm.org/go/ZefVSu5rM-

Some trails here have individual names and others are de-facto named 
after their blaze color, e.g. "Red trail". In the former case, I tagged 
them with the blaze color and symbol (shape), e.g:

highway=path
name=Wiggin
colour=red
symbol=square

While color and symbol isn't rendered on the default OSM layer, I've 
used this data on my own maps.

Something like the above seems like the cleanest solution to me, 
although Joe's suggestion, name="Wiggin (red)", may be an acceptable 
compromise.

For unofficial trails, I'm inclined to map them as any other trail (i.e. 
what's on the ground) with all other relevant attributes (surface, 
width, trail_visibility). I agree with Joe that it's better to 
differentiate between official and unofficial trails with access tags, 
such as access=yes vs access=permissive (or access=private if 
applicable) rather than noting it in the name tag.
