Google Earth is popular because it offers three dimensional view of real images captured from space!!!
One feature that captures the attention of each and every end user of the Google Earth software application is that it is a three dimensional representation of the Earth. The developers of the Google Earth software application have released the three dimensional buildings feature for the end users of the software application. What this feature does is that it enables the end user to not just view the terrain of the earth in the Google Earth software application in a three dimensional view but also the buildings in the cities in three dimensions. The buildings in the cities are created by the developers and the data is collated with the Google Earth software application to create a three dimensional imagery of the city.
However, not all of the earth is offered in three dimensions. Currently, the three dimensional view of the buildings and structures is restricted to some cities in the United States of America and Japan. While the developers are working fast on offering this feature for all other cities as well, the completion of the whole process will take time. However, despite the fact that the Google Earth software application does not offer three dimensional view of each and every city on the earth yet, it is still the most popular software application as far as mapping software applications are concerned. Why is this so??
The reason why the Google Earth software application is the most popular software application around despite the fact that it does not offer three dimensional view of each and every part of the earth is that the Google Earth software application offers a real view of the earth. While other mapping software applications make use of illustrated maps, the Google Earth software application makes use of actual images captured from satellites orbiting the earth in space. Hence, if you zoom into your city from outer space using the Google Earth software application, you will see your city and your home exactly as it was seen by the camera in the satellite in outer space. That is to say, the image that the end users view on the Google Earth software application is the real thing. It is not an artificial image created on the earth. Rather it is a real photograph of your city and your home captured by the satellite. The Google Earth software application makes use of millions of such images to create a mosaic that forms the Earth in the Google Earth software application. The high quality images occupy terabytes in term of memory. When any end user of the Google Earth software application accesses the software application, the Google Earth software application connects to the servers owned by Google to download the images and data that the end user of the software application wishes to view. The best part is that the end user does not access more than a few hundred megabytes of images at a single point of time. Hence, the end user is capable of using the Google Earth software application without having to actually download terabytes of data as images.
