Over the past decade or so, the quality of satellite images contained in Google’s maps products has improved dramatically, according to techspot, amedia outlet. It’s easy to see this when you use the timeline slider in Google Earth to look at satellite images from a few years ago. Most of the images captured over the past few years are easy to notice, while snapshots taken a decade or earlier are usually black and white and difficult to identify.
Google has now managed to categorize a large number of images to complement its various mapping services. Thomas Escobar, Google Maps senior product manager, said in a new blog post on the matter that the Street View vehicle has now traveled more than 10 million miles. Escobar points out that this is equivalent to more than 400 circles around the earth.
At the same time, Google Earth now contains high-definition satellite images from various providers covering more than 36 million square miles. According to Escobar, Google Earth now covers 98% of the world’s population.
The Street View image set is even more impressive. As you know, Google has a huge fleet of people that collect street-level photos around the world. But did you know that Google also uses boats, sheep and even camels to help collect images in remote areas?
In addition to collecting images, the tech giant uses a process called photogrammetry to integrate everything to create an accurate picture of the real world. Google’s approach is unique in that it leverages images from multiple sources and is accurate to meters.
