It's fake, but realistic looking. I think it would be better if fake data looked fake than looked realistic, but wasn't. That way people are more likely to spot that it needs fixing, and think about fixing it. Probably using something like a weighted average of the nearest data we do have, so that large voids turn into over-smooth areas would be as good a compromise as any. > Secondly is hydrographic-model approach, which is what I believe the > GGIAR guys do, and it's how voids are traditionally filled by the > professionals (generally manually or at least labour-intensively, not > like us upstarts who just think on a fully automated, global basis ;-) > ). I thought that the point of open street map was that we have lots of labour available from volunteers. :-) Robert (Jamie) Munro -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkjPzU4ACgkQz+aYVHdncI00wwCgzsumaK+a6SEla8yNw3XVfzc4 v30AoNP8J2a2sIq46jjzNCegHT01knyb =/G7O -----END PGP SIGNATURE----- _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
