# 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).
