Automatic enhancement of CityGML LoD2 models with interiors and its usability for net internal area determination

Where Level of Detail (LoD) allow City Geography Markup Language (CityGML) models to be shared over different application domains, only one LoD defines building interiors. As there are potentially numerous applications with a need for building interiors (but not with all the details as defined in LoD4), in order to attain a larger applicability...

Automatic generation of CityGML LoD3 building models from IFC models

CityGML is a standardized data format used to store the semantic information and geometries of buildings and other object classes of 3D city models. The Level of Detail of current state of the art city models (LoD2) is not sufficient for accurate environmental simulations like noise, the solar potential of windows and other types of analyses. An...
