How often is Google Earth updated?

All images in Google Earth are updated anywhere from seconds to two years. The images take time, and they are continuously collecting them from all over the world, so it is a bit hard to find out which location will have newer, most updated or even highest-resolution images.

The images on Google Earth are always updated as they try to provide users with the highest-resolution images possible of the different locations available. Working on the update of the images involves checking for previous images and new acquisitions, which tends to be a very slow and detailed process even for experts.
