Data Format
This is the latest version from 2025-01.
Our base data format is GeoJSON. This reads easily into many web applications as well as GIS software. Find out more about this standard format here geojson.org.

Geometry
Geographic projection id EPSG:4326 (WGS84).
GeometryCollection and MultiPolygon geometries are resolved to individual features.
Feature ID
ONEGEO building identifier. It can occur multiple times in order to connect building parts.
alphanumeric
Feature Attributes
| Attribute | Description |
|---|---|
| name | building name alphanumeric i.e. Chrysler Building |
| type | type of building alphanumeric i.e. commerce, residence |
| height | total building height, meters numeric |
| heightScore | quality index for height sources and precision numeric range: 0..1 |
| minHeight | height at which a building part starts vertically (floating), meters numeric |
| levels | total building levels numeric |
| minLevel | levels at which a building part starts vertically (floating) numeric |
| color | dominant color of building facade named colors, rgb() or #hex values alphanumeric |
| material | dominant material name alphanumeric i.e. concrete, glass |
| shape | building shape if unusual alphanumeric i.e. sphere, pyramid |
| roofShape | roof shape alphanumeric i.e. skillion, flat, dome |
| roofHeight | roof height (included in total height), meters numeric |
| roofLevels | roof levels (add to buildings levels) numeric |
| roofColor | dominant roof color alphanumeric named colors, rgb() or #hex values |
| roofMaterial | dominant roof material name alphanumeric i.e. tiles |
| roofDirection | direction where a roof is facing - clockwise in degrees from north numeric |
| date | date on which the feature was last edited numeric i.e. 202103 |
| built | date on which the feature was built numeric i.e. 196706 |
| 🛠️ area | beta, in development area of the building footprint, square meters (for total floor area multiply by levels) i.e. 152 |
| 🛠️ ele | beta, in development terrain elevation, meters i.e. 491 |
| ⚠️ buildingId | marked for deprecation - use feature IDs instead for complex buildings: used to connect building parts alphanumeric |
| heightSrc | use heightScore instead deprecated |
| origId | deprecated |
| partId | deprecated |
| roofAngle | use roofHeight + roofShape instead deprecated |
