Abstrakt EN: The paper has explored 3D data management from multiple perspective. The focus of the data management issue in this paper has not been restricted to 3D Cadastre, but rather to a broader 3D GIS to ensure that all capabilities and issues that exist in different related fields will assist and affect in the data management of 3D cadastral data. In functional requirements for 3D cadastral data management, the categorisation of 3D parcels at an increasing level of complexity is discussed. This lead to a discussion on options for storing 3D cadastral data in an existing 2D cadastral database that traditionally exists in current jurisdictions. The issues related to adding the time dimension in a 4D cadastre from a database point of view was discussed. A discussion of 3D geometric models based on current research on standards, solid geometry and LADM schema, which in turn led to 3D topological models. The LADM provides a data model that recognises and describes the relationships of a 3D spatial unit to other levels of encodings.
