Adjusting the 2D Hellenic cadastre to the complex 3D world : possibilities and constraints
Tsiliakou, Eva & Efi Dimopoulou
The Hellenic Cadastre (HC) collects information on property objects, in order to cover the entirety of the Greek territory and according to its action plan, this information is in reference with the land-parcel and is analyzed on the two dimensions of the real objects. However, according to Dimopoulou et al (2006), registering property objects in the three dimensional space has become an imperative need in order to optimally reflect all complex cases of the multilayer reality of property rights. Furthermore, according to Papaefthymiou et al (2004) the current developments in social, technological and economical aspects of modern life require Cadastral systems with 3D enabled geometrical and topological models for property registration. However, implementing the 3D concept in the present Cadastral system does not imply the establishment of an absolute three-dimensional registration system, which is not currently feasible. The hybrid Cadastre seems to be the optimal approach for the complex Greek reality, because it involves maintaining the current 2D Cadastre, while simultaneously incorporating the registration of three-dimensional cases and the integration of 3D data types.
