With the various geographic shifts which have occoured, I wonder if GPS mapping will need to be tweeked in affected areas?
Shifts of several metres have been reported, and that may be enough to cause GPS mapping software with 'snap to road' functions to snap to the wrong road now.

Yes, someone on the news earlier this week said this was likley, and mentioned a movement of 10 feet IIRC.
I have been musing on a statement I heard or read that the earth's orbit has shifted. How much will this effect clocks? Will we need more/ less leap seconds?

The figure I saw was 1.8 microseconds (that a day is shorter).
So you will need to put your clocks forward 1 second, around 3500 AD/CE.
I don't think the ORBIT has shifted..but the meridian may have...
"Graham." gurgled happily, sounding much like they were saying:
It'd need a lot more than 10ft for this to be Ilkley.
Yeah, I'd have been rather scared, too.
Oh - SHIFTS...
It would however affect the more sophisticated units that receive additional correction information via a geostationary satellite.
