Hmm, perhaps then tracing it from out-of-copyright maps is not such a bad idea... Although most likely the one-inch maps currently emerging from copyright do not have the field boundaries. >That doesn't mean >they don't have some other more accurate data in a format not readily >reproduced on a printed map - maps such as this one: > >http://maps.nottinghamshire.gov.uk/ >NottsCC.InteractiveMapping.Web.Internet/ >?e=461177&n=360114&mpp=160&layers=SEA.PLA.FP.BR.RB.BOAT >/&hLayer=&hField=&hValue= > >suggest that they might. Hmm, where do you see field information on that? >In areas where there's complete public access (Open Access Land) Ah yes, Open Access... <http://www.naturalengland.org.uk/ourwork/enjoying/places/openaccess/> lets you see these areas superimposed on OS maps, but I didn't see a place to download the whole data set. 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://lists.openstreetmap.org/listinfo/talk
