Google Miniatur Wunderland works, in essence, as Google Street View, with the small, or very small difference, that here we are not touring the real world but the tiny world of a model. Specifically a gigantic railway model with 15 km of tracks from Miniatur Wunderland.
To perform this feat, the result of which you can see in the video you have here above, a miniature Google car has been made, which, like its namesake in the macro world, travels around every corner of the stage collecting images with its mini camera. Of course, this Google project in collaboration with the company Ubilabs, offers 360º perspectives.
Wunderland miniatur It is a model building in Hamburg on an H0 scale with a total area of 4000 m2. The exhibition contains 900 trains, 300,000 lights, 12,000 wagons, 200,000 trees and 200,000 human miniatures. As explained from Google:
Because we capture these images at the "street level" of Wunderland, in Street View you can see many tiny details that are not visible even to museum visitors: deep-sea divers at a county fair, farmers riding a stick Broom, a newly married couple on the steps of the Palace of Justice and a crowd dancing at an outdoor concert.
