Maybe there is a reason why the node is exactly on that position.
Since there is nothing to stop people MOVING a node later, that argument fails. The more I think about it, a SIMPLE rule that any uniquely identifiable POI on the ground should only have one set of tags becomes more attractive. As long as information contained within previous copies of that POI, be they nodes or previous instances of the area are maintained, then nothing need be lost. Any tool that ONLY looks at nodes and ignores areas has a problem anyway, since some POI's WILL only be areas? >> If a renderer doesn't want to use the relationship, they don't have >> to.

THAT was the way I was thinking originally, but in the general rule - since most POI type data can be defined as node or area - then requiring a second node entry for every area is wrong, so providing a fix INCASE an area also has a node is also wrong. -- Lester Caine - G8HFL ----------------------------- Contact - http://home.lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://home.lsces.co.uk MEDW - http://home.lsces.co.uk/ModelEngineersDigitalWorkshop/ Firebird - http://www.firebirdsql.org/index.php _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
