When I created the relation (end of 2008), I was doing a mass tidyup of London Borough boundaries, I primarily created the relation so I could quickly pull up a neighbouring boundary relation in JOSM when I found another section of it. I was idly wondering if it could be turned into an is_in relation for some point for the Greater London region, even though it is implicit through the Greater London polygon (which may or may not be complete). Thanks for raising my attention to this, since I've now discovered that SteveC deleted the boundary relation for Tower Hamlets in Feb 09.... I think it's time for another tidyup session... -- Regards, Thomas Wood (Edgemaster) _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
