Every building on Earth. All 2.75 billion of them. Mapped in 3D. For the first time ever. πποΈ
Scientists at the Technical University of Munich just released the GlobalBuildingAtlas β the most comprehensive digital map of human-made structures ever created.
Published December 1, 2025 β this is breaking news from just DAYS ago.
What makes this incredible:
This isn't just a flat map. It's a full 3D model of every single building visible in satellite imagery from 2019. Every house, apartment, skyscraper, warehouse, hut, and structure across the entire planet.
2.75 billion buildings
506.64 billion square meters of built-up area
2.85 trillion cubic meters of total building volume
3Γ3 meter resolution β 30 times finer than previous global maps
The previous largest dataset? 1.7 billion buildings. This new map adds over 1 billion more structures that were never digitally mapped before.
What's revolutionary about this:
For the first time, we have complete coverage of underrepresented regions β rural Africa, South America, Southeast Asia, remote villages, areas that have been invisible on global digital maps until now.
97% of the buildings (2.68 billion) are rendered as LoD1 3D models β simplified 3D representations showing the footprint, shape, and height of each structure.
The team used PlanetScope satellite imagery and advanced AI machine learning pipelines to detect building polygons, estimate heights, and construct 3D models from space.
Why this matters:
π Climate Research β Buildings account for 40% of global energy use and emissions. This map enables precise modeling of urban heat islands, energy demand, COβ emissions, and climate adaptation strategies
ποΈ Urban Planning β Cities can now identify overcrowded neighborhoods, plan housing, schools, hospitals, and infrastructure based on actual building volume per capita
β οΈ Disaster Management β Flood risk, earthquake vulnerability, and emergency response planning can now be assessed building-by-building globally
π Measuring Inequality β The map introduces "building volume per capita" as a global indicator β revealing social and economic disparities by showing how much living space people actually have
π± Sustainable Development β Directly supports UN Sustainable Development Goal 11 (inclusive, resilient cities) by providing the data needed to make cities more equitable
The Data is FREE:
The entire GlobalBuildingAtlas is open-source and freely available on GitHub, TUM's mediaTUM server, and Google Earth Engine. Anyone can download it, explore it, use it for research.
What the numbers show:
Asia: 1.22 billion buildings (largest concentration in eastern China)
North & South America: 560 million buildings
Africa: 540 million buildings
Europe: 400+ million buildings (densest in central Europe)
This is humanity's footprint.
Every home we've built. Every city we've constructed. Every structure that shelters, feeds, employs, or houses us β now visible, measurable, analyzable.
From megacities to remote villages. From skyscrapers to single-story homes. All mapped. All in 3D.
We can finally see ourselves from space β not just as people, but as builders. ποΈπ
