| | # GlobalBuildingAtlas: An Open Global and Complete Dataset of Building Polygons, Heights, and LoD1 3D Models |
| |
|
| | [Paper](https://essd.copernicus.org/preprints/essd-2025-327/) |
| |
|
| | ## 1. Overview |
| |
|
| | **GlobalBuildingAtlas** is a dataset providing global and complete coverage of building polygons (**GBA.Polygon**), heights (**GBA.Height**), and Level of Detail 1 (LoD1) 3D building models (**GBA.LoD1**). |
| |
|
| | It is the first open dataset to offer high-quality, consistent, and complete building data in 2D and 3D at the individual building level on a global scale. |
| |
|
| | > ⚠️ **Note:** |
| | > This repository contains **only building polygons delivered under Open Database License (ODbL)** (*GBA.Polygon*) of the GlobalBuildingAtlas dataset. |
| | > These building polygons are from [**OpenStreetMap**](https://www.openstreetmap.org/) and [**Microsoft**](https://github.com/microsoft/GlobalMLBuildingFootprints). |
| | > Consequently, this repository (*GBA.ODbLPolygon*) is distributed under the **ODbL license** as well. |
| | > For the complete dataset, please refer to [mediaTUM](https://mediatum.ub.tum.de/1782307). |
