Abstract [en]
The current three-dimensional (3D) property units are in most countries registered using two-dimensional (2D) documentation and textual descriptions. This approach has limitations of representing the actual extent of complicated 3D property units and also to provide an overview of the 3D cadastre in e.g. city centers. To improve the representation and visualization of the 3D cadastre we could utilize 3D digital models. To facilitate this several requirements needs to be considered such as organizations, legal rules, coordinate reference systems and height systems, data standards, geometry and users. In this study, we formulate these requirements and then develop a framework for integration of 3D cadastre and 3D digital models. The basic idea is that cadastral information (stored the in Land Administration Domain Model, LADM) are integrated with Building Information Modelling (BIM) on building level for accurate representation of legal boundaries and with Geographic Information System (GIS) on city level for visualization of 3D cadaster in urban environments. The framework is implemented and evaluated against the requirements in a practical case study in Sweden. The conclusion is that the integration of the cadastral information and BIM/GIS is possible on both conceptual level and data level which will facilitate that organizations dealing with cadastral information (cadastral units), BIM models (architecture, engineering and construction companies) and GIS (surveying units on e.g. municipality level) can exchange information; this facilitates better representation and visualization of 3D cadastral boundaries.
