Australia's
adjusted national GPS coordinates were recalculated and adjusted
to keep pace with changing navigation technology. The continent
moves north by seven centimeters (2.76 inches) every year due to
its position on the world's fastest moving continental tectonic
plate, according to Geoscience Australia. The country's
coordinates were off by 1.5 meters (4.9 feet) due to years of
natural shifting.
Satellite navigation systems on smartphones align with digital map
information and autonomous vehicles could show you are in the
middle of the road or you are in another lane. The Geocentric
Datum of Australia, the nation's local coordinate system, was last
updated during 1994.
Incidentally, the Indian Subcontinent in the past was moving
towards Asia at a speed of about 6 inches per year. When they
collided, the Himalayas came into being. They are still growing,
but since then, India is only pushing into Asia proper at about
2 inches per year.
