Part 3/9:

How does Google accumulate data to fill this digital quilt? Through an all-terrain operation. Street View cars, equipped with nine high-resolution cameras and laser sensors, capture 360° images, while boats, snowmobiles, and even camels map hard-to-reach terrains. Each method contributes to building a comprehensive geographical database.

Mixing creativity with technology, Google employs photogrammetry to stitch billions of images into cohesive 3D models. The structure from motion technique ensures the images are properly aligned, while aerial and satellite imagery fills the gaps where ground support can't reach.
