BaalChatzaf Posted January 25, 2017 Share Posted January 25, 2017 Australia is moving 2.7 inches northward per year and rotating clockwise. If driver-less cars become common their, their GPS based steering systems will have to be recalibrated several times a decade, because the error could cause driver-less cars to be on the wrong side of the road.

And I found this: Quote Driverless cars need Australia's latitude and longitude coordinates to be corrected By Emily Clark Updated 28 Jul 2016, 1:20am PHOTO: This picture shows approximately how far Australia will have moved from 1994 to 2020. (Aerometrex) RELATED STORY: Australia's coordinates out by more than a metre, scientists say MAP: Australia Driverless technology and other intelligent systems like satellite farming require Australia's longitude and latitude to be corrected, scientists say. Australia's coordinates are out by more than 1.5 metres and that could have major implications for new technologies that rely on global positioning systems (GPS). Dan Jaksa from Geoscience Australia is working with a team of scientists from national, state and territory governments to modernise Australia's coordinate system — the datum — to close the gap and avoid problems in the future. This has happened four times in the last 50 years. We're currently using GDA94 (Geocentric Datum Australia 1994) and will move to the GDA2020 next year. This time around, technology is playing a big role. Why do we need to update our coordinate system? Media player: "Space" to play, "M" to mute, "left" and "right" to seek. VIDEO: Australia is on the move by 7 centimetres each year(ABC News) "The cost of not doing this outweighs the cost of doing it," Mr Jaksa said. "At the moment they [smart devices] have to adjust everything because the information you have doesn't line up with the [physical] position. "With the applications that are coming in intelligent transport systems — like driverless cars — if you're 1.5m out then you're in another lane. "So the map information those systems use need to be coincident with the [navigation] system they're using which is GPS. "Quite frankly, we need to update the datum if they're going to become a reality." Mr Jaksa said other areas that will require the new coordinate system are precision agriculture — or satellite farming — and surveying. He did warn that the "dimensions of a property don't change though". "Unfortunately you don't own any of the property next door," he said. What will the new coordinate system actually do? Mark Deuter is the managing director of aerial mapping service Aerometrex. He said the new datum would have "no perceptible effect on people's everyday lives", because we live mostly in an environment that depends on relative measurements. "However there are now global positioning systems that we need to align with," he said. "Australia's — and our coordinate system's — position on the globe is changing. Also from the same media outfit down under, in an alarmish opinion piece: Quote For Australia, the Bureau of Meteorology described 2016 as a "year of extreme events" and the fourth hottest at 0.87 degrees Celsius above the 1961-1990 average. The warming trend is clear. INFOGRAPHIC: The BOM's key 2016 climate facts and events. (Supplied: BOM) Australia is already on average 8 degrees Celsius hotter than the average global land temperature, so further warming means our heat risk is far greater than for other industrialised countries.

Brant Gaede Posted January 28, 2017 Share Posted January 28, 2017 They already drive on the wrong side of the road. Therefore no corrective will be needed until they are driving on the right side of the road. --Brant they have more time than you think (think?!)
