Google Earth is a fascinating tool that allows users to explore the world from the comfort of their own home. Since its launch in 2001, Google Earth has become an invaluable tool for everything from vacation planning to scientific research. But how often is Google Earth updated? Let’s take a closer look.

Google Earth updates its database of satellite imagery on a regular basis, although the frequency of these updates can vary depending on location. In some areas of the world, Google Earth is updated as often as once per week, while in other areas it may be several years before new imagery is added.

According to Google, much of the satellite imagery used in Google Earth is acquired by the company’s own fleet of satellites. However, they also rely on data from other sources, including government agencies, commercial providers, and even volunteers who contribute their own aerial photography.

The frequency of updates for Google Earth also depends on the type of imagery being updated. For example, updates to road networks and points of interest are generally made more frequently than updates to satellite imagery. This is because satellite imagery is more difficult and time-consuming to process and stitch together into a cohesive image.

Additionally, Google Earth also employs a technology called “historical imagery,” which allows users to view past versions of the same location. This can be useful for tracking changes to the landscape over time, such as the construction of a new building or the effects of natural disasters.
