What is the GlobalBuildingAtlas?

The GlobalBuildingAtlas is a 3D map created by German researchers that charts the location and size of 2.75 billion buildings globally using satellite data and AI.

How did researchers create the 3D building map?

Scientists combined nearly 800,000 satellite images from 2019 with an AI algorithm to predict the size and location of buildings worldwide.

What is building volume per capita?

Building volume per capita is a new metric used to measure socioeconomic development, suggesting that more building space per person indicates a higher level of well-being.

3D Map Reveals Earth's 2.75 Billion Buildings

Researchers from the Technical University of Munich have unveiled the GlobalBuildingAtlas, an unprecedented 3D map charting the location and size of 2.75 billion buildings across the globe. Leveraging nearly 800,000 satellite images from 2019 and an AI algorithm, the map provides a detailed representation of urbanization, offering insights into living conditions that traditional 2D maps cannot match. The resolution in urban areas is exceptionally high, approximately 30 times finer than existing databases.

The creation of such a detailed global building map was historically challenging due to the need for specialized laser-scanning satellites. The German team's innovative approach combined existing laser-scan data with AI to predict and map buildings where data was sparse. This has resulted in a powerful tool for studying development, planning urban growth, and preparing for disasters. The map covers diverse locations, from historic structures to dense cityscapes and remote settlements.
