It's what lat/lon should be uploaded to OSM so it's consistent world wide, you don't need to support all sorts of weird and wonderful local datums, even if there is drift due to continental drift etc. Australia is moving NNE about 7cm per year on average, but different parts of the country are moving at different rates. Then there was a quake in New Zealand last year and the southern part moved 30cm closer to Australia, but the northern part hardly moved. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
