As always the Google oke's have a great support system.
4 Granted to answer your question :
At this time, Google Earth supports Windows only; however, we hope to support Mac and Linux OS soon. In the meantime, although it might be slower, some Mac users have had success running Google Earth with a PC emulator.
So try it mate.
126,7 your question re old data :
Google Earth acquires the best imagery available,
most of which is approximately one to two years old.
We recently launched our new Primary Database which includes:
- 15m imagery for the entire globe (EDIT : I think it is the non Green area's which is VERY good !)
- 90m terrain elevation mode data
- Updates to many US cities (
of course)
- Major international expansion including, but not limited to, all major Canadian and Australian cities, Santiago, Buenos Aires, Rome, Naples, London, Luxembourg, Paris, Toulouse, Valencia, Barcelona, Lisbon, and Athens.
(Africa .. who cares ...)
