How often does Google Earth update its images?
The images in Google Earth are updated on a continuous basis. It’s hard to say exactly because some areas may be updated more frequently than others (just because that data is more readily available). While most images are no more than 3-5 years old, you may occasionally see an older image. Keep in mind that sometimes older images are actually of better quality than new images (i.e. there might be a huge cloud over a certain area which encourages using the older, clearer image).
