Ein Forschungsteam aus München hat einen immensen Datensatz aller Bauwerke der Welt erstellt und freigegeben. Der soll etwa bei der Stadtplanung helfen.

Výzkumníci z Mnichova představili první veřejně dostupný GlobalBuildingAtlas. Jde o 3D mapu asi 97 % všech budov na světě. Je v ní 2,75 miliard budov v rozlišení 3 × 3 × 3 metry. Byla sestrojena na základě satelitních snímků a výška budov je odhadována pomocí strojového učení. To bylo trénováno na přesných datech z LiDARu ze 168 měst. Nejvíce budov a zároveň největší objem mají v Asii hlavně kvůli rozvoji v lidnaté Číně a Indii. Afrika má druhý nejvyšší počet budov, ale malý celkový objem. To odpovídá spíše malým budovám. Data naleznete na GitHubu a více detailů pak v článku. (zdroj: slashdot)

Researchers have produced the GlobalBuildingAtlas, which they say is the first high-resolution (3 x 3 m) 3D map of all buildings worldwide.

With the GlobalBuildingAtlas, a research team at TUM has created the first high-resolution 3D map of all buildings worldwide.

Abstract. We introduce GlobalBuildingAtlas, a publicly available dataset providing global and complete coverage of building polygons, heights and Level of Detail 1 (LoD1) 3D building models. This is t...

科学家绘制了全球 97% 建筑物的 3D 地图。地图 GlobalBuildingAtlas 发布在 GitHub 上，采用 MIT 许可证带公地条款限制（禁止商业出售）。数据集涵盖了 27.5 亿栋建筑物，以 3 米× 3 米的空间分辨率绘制了每栋建筑物的轮廓和高度，该地图可用于灾害风险评估、气候建模和城市规划。研究人员利用深度学习工具，基于 2019 年拍摄的约 80 万张卫星影像，创建了 3D 地图。研究发现，亚洲建筑物数量几乎占全球所有已测绘建筑物的一半，约 12.2 亿座。亚洲建筑物总体积也位居全球之首，达到 1.27 万亿立方米，这一结果反映了中国、印度和东南亚地区快速城市化和密集的都市区。非洲建筑物数量位居第二，达 5.4 亿座，但其总体积仅为 1170 亿立方米，以小型低层建筑为主。芬兰人均建筑物体积是希腊的六倍，尼日尔的人均建筑物体积为世界平均水平的 1/27。

Well, here's something you don't see every day: all 2.75 billion buildings of the world shown together in a single 3D map.

Longtime Slashdot reader Gilmoure shares a report from Nature: Scientists have produced the most detailed 3D map of almost all buildings in the world. The map, called GlobalBuildingAtlas, combines satellite imagery and machine learning to generate 3D models for 97% of buildings on Earth. The dataset, 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. Read more of this story at Slashdot.
