According to techspot,In the past decade or so, the quality of satellite images included in Google's map products has greatly improved.It is easy to see this by using the timeline slider in Google Earth to view satellite images a few years ago. Most of the images captured over the past few years are easy to notice, while shots taken a decade or earlier are usually black and white and difficult to recognize.


Google has now managed to classify a large number of images to complement its various map services. Thomas Escobar, senior product manager, Google MapsBlog articlesThe street view survey car has now traveled more than 10 million miles, says Escobar. Escobar points out that this is equivalent to more than 400 circles around the earth.


Meanwhile, Google Earth now includes HD quality satellite images from a variety of providers, covering more than 36 million square miles. Google Earth now covers 98% of the world's population, according to Escobar.

The street view image set is more impressive. As you know, Google has a huge fleet that collects street level photos around the world. But did you know that Google also uses ships, sheep and even camels to help collect images in remote areas?

In addition to collecting images, the tech giant needs to use a process called photogrammetry to integrate everything to create an accurate picture of the real world. Google's approach is unique in that it uses images from multiple sources and is accurate to meters.
