OpenBuildingMap

The original dataset is archived at GFZ Data Services (DOI: 10.5880/GFZ.LKUT.2025.002). The data can be downloaded via the OpenBuildingMap download portal. This data publication provides the OpenBuildingMap dataset, organized per zoom-level 6 Quadkey. The dataset provides information about the occupancy and height of individual buildings. The main purpose of this data collection is risk assessment for natural hazards, but it can be used by anyone in need of a building exposure dataset. Buildings play a critical role in understanding human settlement patterns and are essential for applications such as crisis management, urban planning, energy efficiency, and multi-hazard risk assessment. This dataset contains 2.7 billion building footprints enriched with structured attributes such as occupancy type and height information classified using the GEM Building Taxonomy. It is derived from the integration of the AI-derived Open Buildings and the Global ML Building Footprints datasets and the crowdsourced OpenStreetMap, creating the most detailed and extensive building dataset to date. Data quality has been assessed using intrinsic quality checks and external reference datasets, including cadaster data and the Global Human Settlement Layer. The dataset is provided as GeoPackage files for easy accessibility.
