How often does Google Earth update their areal images?

Answer 1

Google Earth doesn not have a regular schedule for updating imagery, but updates the data as better data become available..

Google Earth says it uses the best available data, and most of the data are 1-3 years old.

Answer 2

They do it annualy. I wondered the same thing too. When they first developed it, the photos were from the 80's or something. Now they update them annualy. It takes them a year to gather footage of the world. They have millions of photography teams everywhere that send their footage to the development center where they update the program with the new footage.

I answered the same over here:

And here's what I said:

Google Earth updates from one to three years, as they say here:

However, some areas are updated more frequently that that, and news can be found here:
