In the master thesis, we analyse the possibility of introducing a 3D cadastre in Slovenia, focusing on the challenges of 3D building modelling. The thesis started with a thorough review of current research and trends at the international level in this field and a presentation of the situation and challenges in Slovenia. Based on the reviewed literature, we developed a more detailed methodology for the experimental part of the research. We propose the concept of building modelling in a 3D environment for the registration of rights and other attribute data related to real estate in the land administration system. For this purpose, we used the data from the building cadastre or the data that must be provided for registering a building in the building cadastre. For the selected cases, we developed 3D models of the buildings based on the concept of indoor spaces as spatial units for defining a real property unit, to which the attribute data stored in a geospatial database relates. 3D modelling can be provided with various software tools. In this thesis, a modelling approach is presented, in which we used the SketchUp and FME software environments for 3D modelling and 3D visualisation. The final result was saved in format 3D PDF. We found that in order to obtain a high-quality 3D model, it is necessary to acquire some additional data compared to the data we need for the current registration of a building in the building cadastre. However, this requirement does not require much additional effort, so we believe that the proposed approach can be applied in practice.
