Anyway, one of the core elements that make Google Maps are tons of images, and to source them, the search giant does what not?
It now covers 98% of the world’s population
Google sources HD satellite images from various providers. So far, around 36 million square miles of satellite imagery has been added to Google Earth. Now, here’s the interesting part: these images cover the areas where almost 98% of the earth’s total population lives.Then there is Street View that gives us an idea of how different places look like in real life. To capture these, Google uses special camera rigs called Trekkers that are fitted on cars, humans, boats, and even camels and flocks of sheep. All of this is to add Street View images of areas where cars can’t go.
After creating a mountainous pile of digital photos, Google uses a technique called photogrammetry to stitch the images together to create a seamless experience for the users.
Google’s added refinements and use of billions of images make it a unique approach.
Google says it has managed to capture around 10 million miles of Street View imagery so far. That is enough to circle the earth more than 400 times.
