Hi 2012/9/18 Ian Sergeant inas66+...@gmail.com If I understand correctly, the differences should only correspond to the amount that our coastline differs from the low water mark? Are we missing parts of the true coastline, is our coastline just inaccurate do you think? Well, to me there

It has also been pointed out that having the two inner poly's of the NSW relation (ACT and Jervis Bay Territory) while having the outer border of the poly incomplete is causing mapnik and nominatim to think that both territories are in NSW. I'm presuming the algorithm being used has difficulty

Hey Michael, Thanks - that made for interesting reading on a subject I knew so little about. And I agree with you, that the best course of action is to obtain the data officially. But in the event of failure/refusal, I'm happy to help out. BTW, in QGIS it's Vector / Geoprocessing Tools /
