No. In the datamodel, it's just a way between two nodes. The nodes are defined in lat, lon, effectively in spherical co-ordinates, hence them being angles. (ignoring not-quite-spherical deformities for now) If a tool says the length is 40,000km, the tool is incorrect. But the datamodel doesn't specify the length, just a sequence of nodes. Tom (assuming you mean -179.99, not -189.99. That would be different) _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
