The Time Factor in Determining How Often Google Earth is Updated

As I’ve referred to in the above paragraphs, the low level, high resolution imagery on Google Earth, such as that of cities and infrastructure is not done by satellites as many people believe. When you zoom in on Google Earth, to the point where you can see your car very clearly parked on your driveway, then that’s the work of aerial photography. If however, your house is a barely discernible brown blob amidst a landscape of psychedelic blurs, then that’s the work of a satellite suspended above the Equator.

Obviously, it takes time for these aircraft to run those photography update missions. They are also run by a number of private companies, not by Google itself, so getting all these images pieced together takes even more time. Finally, the databases cannot be updated until a new version of Google Earth is released which happens every few months. Thus, it takes more time.

On average, imagery of an area is updated every 1-3 years. Some areas are updated more regularly, others have never been updated. It all boils down to where you live and how important Google reckons it is that your area is given fresh images. Most urban areas will have been updated at least once since 2005.

I hope this helps :)

its usually about every 2-5 years sometimes its one as they don't have any set times for new ones. hope this helps.

In that case it must be more than six months.

i think they only update certin parts every year

I think (I could be wrong) once a year
