Does anyone know how long images are "aged" prior to being made

projects, is about 4 years.


Using the same criteria with Google Maps for the Richland, Wa, area,
it's less than two years, maybe even one. But, maybe the update cycle is
4 years, even if it's a relatively new image when it is updated.

I still think it's amazing I can see which way my motorhome is pointing
(can't be sure about the glider trailer, though).


Looking at it more carefully, I realize it's the zoomed in (8 highest
magnification levels) images that are the newest. As I zoom out, the
image changes to an older one from (I'm guessing) NASA satellites.
