2017-10-26 Thread Dave F
(Split to a separate thread) The woods/forest problem is one of the worst tagging cock-ups in OSM. It's bad enough when alternate values are used to differentiate what is actually the same object, but in this case it's also the key! I think you'd be hard pressed to find any area of trees whic
