Right to roam in England and Wales exists only on Open Access Land - which is most unlikely to be cropped. Elsewhere our rights are only on public highways (which include public rights of way) or by permission. Where a public right of way crosses a crop it is likely to be a trespass too go around the crop (off the right of way) but there is a legal right to walk through the crop (and a legal duty on the tenant or landowner to reinstate the right of way through the crop). It would be great to get the field boundary data as in farmed rural areas this is the most useful means of navigation (other than a GPS!), the greatest use I make in the field of OS 1:25k mapping and - for me - the greatest lacuna in OSM! Beyond actual surveying by bearings from points where I have the right to be (which is always going to be a slow, laborious and incomplete process) I cannot see a practical solution other than open-source aerial/satellite photography. OS one-inch (or 1:50k) mapping does not show field boundaries. But is anyone working on out-of-copyright 1:25k (or larger scale) mapping? Mike Harris

It would be nice to route people to the nearest gate. We do have the right to roam but those of who live in the countryside have always had that option we just used our common sense by not walking down the middle of crops. I keep thinking there must be a way to get the field data from the farmers if only it was to sit down and draw from a walking street map.

Has anyone asked? As for adding field boundaries by doing ground surveys, I think this is too impossibly enormous a task, even for enthusiastic OSM mappers. Perhaps we could install GPS devices on every tractor in the country and over a couple of years record ploughing patterns, which would let you deduce the shape of arable fields... -- Ed Avis <e...@waniasset.com> _______________________________________________ talk mailing list talk@openstreetmap.org http:/...
