Contribution of Existing Documentation in 3D Cadastre
Dimitrios Kitsakis & Efi Dimopoulou
Over the last decades, land exploitation is getting more intense in order to satisfy public and private needs of modern societies. The intensification of 3D space exploitation includes complicated rights, restrictions and responsibilities (RRRs) that need to be unambiguously registered. In this direction, the incorporation of 3D aspects of real property to cadastral systems may improve land administration systems, by reducing misinformation and clarifying complex property rights. To achieve this, current legislative and cadastral framework has to be adopted to the emerging needs, or 3D cadastral systems have to be introduced. During the course of time, each country has established a number of databases and registries for various purposes that maintain data describing 3D features of real property. Such data, although may not generate a full 3D cadastral system, can contribute, at some level, to 3D cadastral registration, clarifying complex real property situations. This paper investigates possibilities of extracting 3D property features from existing databases and registries, including availability, format and accuracy issues, taking into account national characteristics and international trends concerning harmonisation and interoperability issues. The investigation is implemented through two characteristic cases of complex property status in Greece that would greatly benefit from 3D representation, supported by existing documentation.
