Automatic conversion of IFC datasets to geometrically and semantically correct CityGML LOD3 buildings
Although the international standard CityGML has five levels of detail (LODs), the vast
majority of available models are the coarse ones (up to LOD2, ie block‐shaped buildings …

New concepts for structuring 3D city models–an extended level of detail concept for CityGML buildings
We propose a new Level of Detail (LoD) concept for CityGML buildings that differentiates a
Geometrical Level of Detail (GLoD) and a Semantical Level of Detail (SLoD). These two LoD …
