Google Maps has captured the world on a large scale. 98 percent of the world is documented, 16 million kilometers are photographed.
The routes that are photographed and visible in Google’s Street View are enough for 400 trips around the world. The photos show a total of around 16 million kilometers. Google Earth covers 98 percent of the world’s population with satellite photos, around 93 million square kilometers. The pictures come from different providers and are of different quality.
Google published these numbers in a blog post and explained that the photos would help Google depict a world that changes daily. Most of the pictures come from our own Street View vehicles. Each is equipped with nine cameras that are particularly heat and cold resistant. There are also sensors and lasers to measure distances. Corners of the world that are particularly difficult to reach are depicted using Street View trekkers. The equipment is carried by people, but also by sheep, camels, or they are attached to boats. Members of the Street View community are submitting additional photos.
Images As A Navigation Assist
Google uses a technique called photogrammetry to compose the images. The process dates back to the beginning of the 20th century and, according to the company, works like putting a puzzle together. If you navigate via Google Maps, the information is fed from all Google Maps data, including the images themselves. According to Google, GPS signals were not sufficient for this. Live-View even guides users via augmented reality.
In Brazil, Google has just mapped 60,000 kilometers of roads. Worldwide, more than a billion people are using Google Maps every month. For a long time, Apple Maps could not keep up with Google, but that should change according to Apple. They plan to spend billions on improving the map service.
