Map of All the Buildings in the World (gizmodo.com)

A research team at the Technical University of Munich has unveiled the GlobalBuildingAtlas, a groundbreaking high-resolution 3D map that encompasses 2.75 billion buildings worldwide, sourced from satellite images since 2019. This new dataset vastly surpasses the previous global compilation of 1.7 billion buildings, offering a resolution about 30 times better than existing databases. The project not only provides a stunning visual representation of urban landscapes but is also a significant tool for socioeconomic and environmental research, enabling analyses of urbanization footprints and poverty metrics across often-overlooked regions. The map features critical metrics such as building height, volume, and spatial relationships, supporting various applications from urban planning to disaster risk assessments. By emphasizing areas like Africa and South America, the researchers aimed to highlight social disparities through metrics like building volume per capita. The dataset can inform climate change studies by mapping energy demand and carbon emissions more accurately, making it a vital resource for policymakers and researchers alike. The interactive map is publicly accessible, allowing users to explore building data globally, reinforcing the importance of tech-driven solutions in addressing urban challenges.
