I agree with the outcome, but not the reasoning. I think its a mistake to justify tagging by the outcome of rendering. The introduction of Mapnik and the proliferation of the Osmarender have done a lot to encourage standards within tagging - but we need to look beyond rendering. If I want to select all of the ways that belong to the london underground system, its not particularly straightforward. >From this point of view, the values of k=v are not significant - its the real-world representation of the objects they represent that matters. > > Robert (Jamie) Munro > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.6 (Darwin) > Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org > > iD8DBQFG8aCHz+aYVHdncI0RArUkAKDV8/Jd/GJ3JROeENwHQQsEk5UmygCgsEP9 > onw2QTMn1y87QbUq8aTrKns= > =af84 > -----END PGP SIGNATURE----- > -- Nick Black -------------------------------- http://www.blacksworld.net _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk-gb
