“Google satellite imagery, 98% of human settlements”

Google Maps and Google Earth have been improving for more than 10 years, but the foundation lies in collecting enormous map information data. So far, Google hasn’t mentioned this, but this time it has revealed the number of images that support map creation for the first time.

When it comes to Google Maps, anyone will think of a vehicle that collects Street View images while running through the streets. According to Google, over 16,033,440 km of Street View images were taken. This is equivalent to more than 400 rounds of the Earth.

Also Google Earth is collected over 36 million m ² HD satellite photos. This is a vast area that can cover as many as 98% of the real population of humans. Google uses photogrammetry to stitch together multiple photos. It is to collect detailed data such as detailed information on areas such as roads and lanes, buildings and rivers, and precise distances between objects without moving from the place.

Photogrammetry is not a different way. Its origins date back to the mid-19th century. But unlike in the past, Google can put together billions of images like a giant puzzle that spreads around the world. It is mentioned that the technology has been improved over the past 10 years since Google Maps was first created in 2004, and it is now possible to adjust in meters from multiple source images such as street view, aerial photography, and satellite imagery.

As Google’s eyes are reaching every corner of the world, it may not be unreasonable for consumer groups in the EU to be wary of Google’s collection of personal information. Related information can be found here .
