Imagine the headache in determining property lines, do you use the global coordinates or the local real coordinates and does your neighbor use the same coordinates? The http://www.forbes.com/sites/trevornace/2016/04/10/lies-beyond-sea-distant-land-looking-towards/#3e8d12bb4b01&apos ;">coordinate system was last updated in 1994 and is certainly due for a refresh.
This sort of reporting (by a geologist in this case=Trevor Nace is a geologist, Forbes contributor, and adventurer.) represents the misconception on anything to do with coordinates, satellites and latitudes and longitudes when it comes to cadastral boundaries here.
We just don't use coordinates as a definition of a boundary corner. Yes we coordinate all new property boundaries here but the coordinates don't define the corner nor the boundary.
One of the common questions I get asked now is in relation to the satellites and boundaries.
Previously it was the Trig (beacons) stations on hills that supposedly we based our start point on.
Interesting times.

Wouldn't the whole coordinate system simply translate to the new system leaving everything in situ?

Yes you're right. There's really nothing to this other than suitable mathematical formula to convert.
We went through similar with AGD66ã84 to GDA94.
That moved coordinates 212 metres (approx.) north easterly which was a noticeable leap and easily seen if misused when overlaid on an aerial image. (assuming that was GDA94 and not AGD66.)
I'm not sure what he meant by 'local real' as opposed to 'global' coordinates.
Cool, another article on Aus coordinates that will leave the reader stupider for having read it. We will need some more, closer to the date though. Some TV news reports for those who don't read
If you're interested here's http://www.icsm.gov.au/gda2020/gmiwg.html&apos ;">a link.
[INDENT]WOW, obviously ICSM has prepared for this. Didn't read all 48 pages, but enough to see y'all are "ready".[/INDENT]

NAD83 was a stroke of mathematically violent genius. It allowed countless Surveyors to enter the world of geodesy, without actually learning advanced geodesy.
With all of its trade-offs I consider it a perfect stepping stone to the 2022 rollout.
The downside now is to get us old guys to let go of the grotesque mutilations we hold near and dear, while not flushing a few hundred years of boundary establishment doctrines and law. We would do well to study the experiences of our friends down under.
This change is likely to be the greatest Rollercoaster ride of our generation in this Profession. We are now adding 'coordinates' to the order of calls wether we like it or not. This means cleaning up Statutes and protecting land owners from ignorance, both ours and theirs.
Ramble mode off...

For those Aussies that may be under the impression that the translation will effect the ground surface in a rapid motion:
