97% of Buildings On Earth 3D-Mapped (nature.com)

(Thursday December 11, 2025 @10:30PM (BeauHD) from the building-polygons dept.)


Longtime Slashdot reader [1]Gilmoure shares a report from Nature:

> Scientists have produced the [2]most detailed 3D map of almost all buildings in the world . The map, called [3]GlobalBuildingAtlas , combines satellite imagery and machine learning to generate 3D models for 97% of buildings on Earth. The dataset, [4]published in the open-access journal Earth System Science Data on December 1, covers 2.75 billion buildings, each mapped with footprints and heights at a spatial resolution of 3 meters by 3 meters. The 3D map opens new possibilities for disaster risk assessment, climate modeling and urban planning, according to study co-author Xiaoxiang Zhu, an Earth observation data scientist at the Technical University of Munich in Germany.

"Imagine a video game with the world's buildings already mapped in basic spatial dimensions!" writes Gilmoure.

Rats, as an architect I was hoping it might be useful to the general construction industry, but not at 3m accuracy.

True, but I figure it'll be built into the next version of Microsoft Flight Simulator.

I saw a video of a DJI drone with a [1]mounted LIDAR scanner [youtube.com] and it was mapping down to the power wires so that might just take another 10 years to get everything.

I'm wondering about that, because for years Google has had better resolution, but not 97% coverage.

Maybe that's the worst case, and it's better in areas with better satellite photographs available. I think Google uses aerial photography too, to get views from different angles.

It just scales the footprint of a building on a given plot into the 3rd dimension by giving it a height.

Everything, of course, turns into little skyscrapers.

Yup, it has no concept of extensions it seems.

My own house is two-storey but with a small single-storey extension (containing the kitchen). This dataset has the whole house at 2.3m high, which is just plain wrong - the majority is around 4.6m high, with the extension being 2.3.

I suspect there's several different versions of something like this, [1]only [gadgetreview.com] [2]with [futurism.com] [3]interior [theverge.com] [4]floorplans [technologyreview.com].

I mean, sure, the real estate industry. But I like to imagine high-tech cat burglars using them to plan their heists. More likely someone will turn it in to copware to sell to SWAT teams for planning drug busts.
