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
- 90m terrain elevation mode data
- Updates to many US cities
- 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.
This is my signature.
