Ways are IMHO somewhat mis-designed; at that point I agree with you. i must admit that I have not too much of a deep insight into some parts of the data model - due to being involved since just 4 weeks now. Moreover, IMHO ways are completely obsolete. Every kind of attribute you need can be represented within a node. And it can be represented _easier_ by just attributing the nodes. Think of the third world, where roads are often not covered with tarmac - - the surface changes every now and then. With OSM you have to split it up in several ways, each attributed accordingly. All you would need is an item or *tag* k='connect' v='<node_id>' So you could connect nodes to a way, and you could easily turn two nodes within a road into a bridge if it has not been set appropriately before. Any renderer has to use the nodes anyway to make up a "way" so it has to look at the nodes - WHY look at and interpret the ways additionally? Admittedly any software would need a fix on that. But the major part (dropping the ways and setting the connections) should be a matter of a simple script. Just my 2 cents on your thoughts - -- - -m*sh- ___________________________________________________ | harry w. graner |mail: hy [_at_] sha-mash [_dot_] de |--------------------------------------------------- [public gpg-key on request] take a look at my blogs: http://yMao4OSM.blog.de -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIbcEl+62Q1j2JM1YRAmZWAJ9iJAYD+zD86NqQc31WBXhDE0MsRACcCrfC qXcy9tuXsL8+2GzeXgvVjNU= =95dP -----END PGP SIGNATURE----- _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
