Re: [talk-au] suburb boundaries import
The Dept of Lands database was said to be 94% correct in 2007 and improving. Most of their errors relate to the house numbers on a street, and I would assume that their suburb boundaries are correct. This data should take precendence over ABS data. Regards, Narelle. 2009/3/8 Franc Carter franc.car...@gmail.com: I wonder if this is because the data is/was off when it was created(2006) or because the boundaries have changed?

Any thoughts on how to work out the real boundary when the ABS data disagrees with commonly known boundaries? I don't know why I didn't notice this when I previewed the data, but the ABS data shows the boundary for my suburb going right down the middle of my street (when I believe it to be one street over). This puts my house in the next suburb over. I suspect the ABS data is wrong, but any thoughts on how to find out for sure?

Re: [talk-au] suburb boundaries import
Hi. 2009/3/8 Franc Carter franc.car...@gmail.com I assumed it is copyrighted however, so not a valid source for OSM ;-( Yes I agree. Given the complicated nature of the boundary in this area (according to the Lands dept) I don't think copying their data without permission is a good idea (and their license would not allow this). The ABS boundary does actually disagree with the street signs though, so when the import is complete (it only has the relation for the suburb on one side of the boundary at present) I'll probably move it to be mid-way between the streets. This is a good approximation of the current local knowledge. - Ben Kelley. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
