If you want a nameless map of streets and natural features, just go straight to the source and use OS VectorMap District. It's complete, consistent, reliable, well plotted, and has a sane licence. There's absolutely no point involving OSM. I'm speaking from some experience here. Every month for our magazine I produce a set of maps from OS OpenData (in this case Meridian2 rather than VMD, because we're working at roughly 1:70,000 and Meridian2 is better suited for that). I did once experiment with using OSM data. It was really painful. OSM's strength is in its rich data. Mindless tracing from OS StreetView, as others have said, destroys the motivation of others to make the data rich. I've seen this in Worcester, where an excellent quality map advancing at moderate speed has now largely drawn to a halt after some thoughtless OS tracing. No-one gains from this. OSM gets a worse map in the medium (not even long) term. Prospective users of the map data don't gain because they could have used OS anyway. I guess the one use-case is short-term use in OSM-derived products (such as Garmin .img files), but if one-tenth the effort spent on tracing had been spent on a utility to intelligently merge OSM with A.N.Other source without uploading it, that'd be much more sane. OS StreetView is a useful tool in moderation, for checking your own surveying and for filling in little gaps here and there. To get back to the original point, I support efforts to make the Contributor Terms compatible with this and other attribution-only licences. But some of the mindless tracing really makes me weep. cheers Richard -- View this message in context: http://gis.638310.n2.nabble.com/OSM-legal-talk-OS-Opendata-the-new-license-tp5538273p5580714.html Sent from the Legal Talk mailing list archive at Nabble.com. _______________________________________________ legal-talk mailing list legal-t...@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
