The order in which the data got inserted was quite conservative (low risk). It inserted data form nodes up - nodes for the ways for the relations and didn't really do much grouping to keep the number of transactions low -- Franc ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

That's not difficult, especially since I'd suggest a dry run or two before hand, you can find all the data via XAPI and then use JOSM to send a delete and then send up new boundary data soon after. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

I think you are right about a re-import, we have learnt a bunch of things since the first import which will hopefully make a fresh one better. I can think of ways around most of the issues with a delete/rebuild - one issue that doesn't jump out with a solution is how to minimise the amount of time that no data exists and hence we have gone backwards a bit. cheers > > ___ > Talk-au mailing list > Talk-au@openstreetmap.org > http://lists.openstreetmap.org/listinfo/talk-au > -- Franc ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

The ABS boundaries seem to be approximations, I'm overly familiar with one postcode delivery area and the ABS boundary doesn't match. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
