<http://www.raggedred.net/codepoint/> I see - so you can use your judgement to work out the area of a postcode based on its centroid and the streets and buildings nearby. Since this isn't using any kind of ground survey to check the data, I wonder if it would be a suitable task for a bot? A program making guesses about postcode areas might not be any more fallible than a human doing the same task. Of course it could only be done in areas that had already reached a high standard of completeness, ideally with buildings traced as well as streets. Or, perhaps, the robot could make suggestions which a human would then accept or reject, so that 95% of the area could be covered, with human assistance for the last few tricky bits. -- Ed Avis <e...@waniasset.com> _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
