Fig. 3.45 CityFurniture database schema

The geometry of city furniture objects is represented either as a surface-based geometry object (LODx_BREP_ID, where 1 ≤ x ≤ 4) related to table SURFACE_GEOMETRY, as a point- or line-typed object (LODx_OTHER_GEOM, where 1 ≤ x ≤ 4) or as implicit geometry LODx_IMPLICIT_REP_ID, LODx_IMPLICIT_REF_POINT, LODx_IMPLICIT_TRANSFORMATION with 1 ≤ x ≤ 4). Optionally terrain intersection curves can be stored for city furniture objects.
