Geometry
Geographic projection id EPSG:4326 (WGS84).
GeometryCollection and MultiPolygon geometries are resolved to individual features.
Feature ID
Building Identifier. It can occur multiple times in order to relate building parts.
Original ids are used with a prefix.
Feature Attributes
| Attribute | Description |
|---|---|
| name | building name i.e. Chrysler Building |
| type | type of building i.e. commerce, residence |
| partId | for complex buildings: id of a building's part |
| height | total building height - in meters |
| heightSrc |
source type for height attribute, possible values are: unknown manual ai photogrammetry lidar |
| minHeight | height at which a building part starts vertically (floating) - in meters |
