Using a diverse array of datasets, a team at the Technical University of Munich released GlobalBuildingAtlas, the first high-resolution mapping model featuring every structure in the world at a given point in time. However, the open-source project isn’t about bragging rights. With over 2.75 billion buildings detailed in the map, the endeavor will help create accurate analyses of urban structures, volume calculations, and infrastructure planning around the planet. “3D building information provides a much more accurate picture of urbanization and poverty than traditional 2D maps,” research lead Xiaoxiang Zhu said in a statement. “With 3D models, we see not...
