摘      要：There are different processes in 3D urban land administration in which spatial analysis plays an underpinning *** 3D data models,Industry Foundation Class(IFC)provides the potential capabilities for modelling legal and physical dimensions of urban ***,performing spatial analysis using IFC files cannot address the on-demand spatial analysis requirements of 3D urban land *** response to this limitation,3D data needs to be stored in a spatial database to enable spatial analyses required by different ***,in this paper,by considering spatial analysis requirements in 3D-enabled urban land administration,an IFC-based database schema is ***,a methodology for transforming Building Information Modelling(BIM)data into the proposed schema is *** methodology includes seven steps:designing the architectural model and adding legal data,georeferencing,IFC data validation and cleaning,mapping process,database data validation and cleaning,spatial analysis,and *** demonstrate the feasibility of the proposed database,three datasets are implemented in the ***,a new method for modelling legal spaces with oblique structures and two applications of spatial analysis in 3D urban land administration are provided.
