Google Earth shows you images in actual time. High resolution satellites and commercial satellite companies such as DigitalGlobe operates hundred kilometers above the planet earth. It means that they see only a small part of planet earth with cameras as they track over. They go across the planet earth every 90 minutes. The imagery of the program Google earth is best when the sun is at a high angle and there are no clouds in the sky, the satellite goes over. Once the imagery is taken, it will take time for processing the data by a profitable provider before it is available for customers.
Google is one such of customer which evaluates the new images against the recent images to determine whether the new images are good than the recent. This process takes much time, when you think of amounts of land mass. For significant areas with large populations, this process involves people. Once an imager is chosen, it has to be processed into coordinate as well as format system of Google Earth’s databases. It also goes through quality control processes and before getting distributed to live Google Earth database serves, it also feeds in a processing system.
It is this reason why you do not find out images younger than about six months in the program Google Earth. Updates take place after every 60 days in Google Earth. Not all the images come from the satellite in Google Earth. Many images come from the aerial photographers in airplanes taking pictures with high resolution cameras. Some of the images come from aerial balloons and kites photography as well. Google get images from a wide variety of different providers. Google also obtains imagery from City or state Governments. As images come from different sources, the process to obtain the images in Google Earth is quite difficult and involves great deal of efforts and time as well.
