Australia Has Moved 1.5 Metres, So It's Updating Its Location For Self-Driving Cars (cnet.com)

Posted by msmash on from the changing-world dept.

An anonymous reader shares a CNET report: Australia is changing from "down under" to "down under and across a bit". The country is shifting its longitude and latitude to fix a discrepancy with global satellite navigation systems. Government body Geoscience Australia is updating the Geocentric Datum of Australia, the country's national coordinate system, to bring it in line with international data. The reason Australia is slightly out of whack with global systems is that the country moves about 7 centimetres (2.75 inches) per year due to the shifting of tectonic plates. Since 1994, when the data was last recorded, that's added up to a misalignment of about a metre and a half. While that might not seem like much, various new technology requires location data to be pinpoint accurate. Self-driving cars, for example, must have infinitesimally precise location data to avoid accidents. Drones used for package delivery and driverless farming vehicles also require spot-on information.ABC has more details.

    Somehow I suspect it's a matter of centimeters rather than nanometers. Need less hyperbole and more accuracy!

      Good collar, Pedant Police, but move over now. I'm with the Pedant FBI. I'm taking charge of this investigation.

      Nanometers may be small, but they're not infinitely small, which is what infinitesimal means. They're barely even any closer to infinitely small than centimeters. Also, we wanted to be more precise here, not less, so what you'd really want in this situation is infinite precision, not infinitesimal precision.

      Let's keep it pedantic out there, citizens.

    If it was the case we would be in deep trouble considering the typical error in GPS. That is the reason why other sensors like LIDAR and cameras are also used. GPS is for having a general clue where you are, and 1,5 m accuracy would be plenty for that.

    Does this mean that Apple Maps is now correct? I'm tired of seeing so many Kangaroo's drive off into the Ocean because they relied too heavily on the Maps app.
