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
The following list represents all potential attributes. Only populated fields are returned (no null values).
Availability varies based on regional data sources and quality.
| 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 |
| orient | orientation of a building (longest side) - clockwise in degrees from north numeric |
| 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 | area of the building footprint in square meters (multiply by levels for total floor area) |
| volume | volume of the building body in cubic meters |
| ele | terrain elevation in meters |
| buildingId | deprecated use feature.id instead |
| heightSrc | deprecated use heightScore instead |
