The boundary representation (B-Rep) method is used to describe the geometry of city objects (Groeger and Pluemer 2012). B-Rep is one of the common surface models with several structures, such as triangular irregular networks and tetrahedronised irregular networks which consist of 2D and 3D ...
Keywords: CityGML, ADE, 3D GIS, 3D city modelling Introduction The CityGML standard [1] of the Open Geospatial Con- sortium (OGC) is the staple open data model and format for the storage and exchange of semantic 3D city models. It is used in several countries around the world for a ...

If you fall into a situation whereby you cannot boot the system and are forced to format the disk on which the operating system is installed (in most cases, this is where malware infections hide), you will lose all data stored within that drive. This is the advantage of having multiple ...
It extends the bldg:Room feature, which is available only in LOD4, doubling as an example of an ADE that is dependent on the LOD. UtilityNetworkADE [28–30] enables modelling utility networks in CityGML. It tailors the data model including the utilities (e.g. freshwater and electricity) ...
One such virtual 3D city model, particularly the Open Geospatial Consortium (OGC) standardised and open data format of City Geographical Markup Language (CityGML) [16,64], has provided a significant boost in the development and visualisation of urban energy data [65]. 2.4. CityGML CityGML, ...

Even the most relevant standard, IndoorGML, only focuses on modelling indoor space for lightweight navigation purposes, required for the components of navigation networks. These existing standards lack the means to express the most basic indoor location information. Indoor location information constitutes ...
