Given there is probably no "right" way to do this I would adopt the same approach in this situation and keep it simple. Wall (the origin of the boundary) or fence the actual "barrier" at this time, it is up to you. My preference would be wall. Dudley Sent from my iPad On 3 Jan 2013, at 14:5

I hadn't looked at the South of Durham around Houghall before, that is fantastic. I had seen the centre was well mapped, but to go to the detail of individual trees.

I was inspired by "Strange but Untrue" mapping from Bowburn and South of Durham City. She did amazing detail with the footpaths, types of barriers, and gates. She also went on some interesting walks by the looks of it. Over a year ago, I did some tracing to make a line of barriers and landuse from

While I agree that high data density is an issue, I can't see why this is a strong argument for not tagging land use in rural areas, as even if we do draw big polygons to distinguish farmed land from woodland from moors from scree slopes etc, these areas are so big that it doesn't make rural data t
