It would be cool to see a comparison the other way round: testing the OS data for accuracy using OSM as a reference. In inner London I think there are about 5% of names missing from OS - mostly semi-private drives or estates, but nonetheless signposted and addressable - so I think they would score no higher than 95%. (OS Street View is a bit better, I'd say that only about 2% of roads that exist are missing from it, and the 'false positive rate' of Street View showing a road where nothing is on the ground is almost nil. It's not as easy to do automated comparisons however. These numbers are totally off the top of my head and apply to London only.) -- Ed Avis <e...@waniasset.com> _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
