Data Format

Data format is GeoJSON.


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.
