Scientists at Technical University of Munich (TUM) have unveiled GlobalBuildingAtlas, the first global, high-resolution 3D map of Earth’s man-made environment. The atlas covers about 2.75 billion buildings around the world, using satellite imagery from 2019 and offering a resolution roughly 30 times finer than previous global building maps.
Each structure is represented at a fine resolution of about 3 × 3 meters, enough to estimate building height, volume, and density. Around 97% of the buildings are modelled as simplified 3D LoD1 geometries, not highly detailed, but sufficient for large-scale computational modelling.
