Yep, quite true. That said, given the complete failure of the most other government agencies to release the real gazetted boundaries under a free license, having the ABS data I think is better than nothing, unless you can obtain more fine grain data from on the ground surveys. Licensing aside (as that has been discussed in length in other threads), is anyone planning to mass import the ABS 2011 suburb/postcode boundaries? _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
