3D Cadastre Development in Hungary

Geometric part of the Unified Hungarian Land Registry (Cadastral maps) has been operating in standardized environment since 1996. MSZ 7772-1 Standard on Digital Base Map (developed by Institute of Geodesy Cartography and Remote Sensing, FÖMI) — based on the pre ISO and CEN standards on Geographic Information — defines a 3D relational database model for cadastral maps and linked attributes. Till now 3D capacity of Cadastral Map Databases has not been utilized. In Unified Hungarian Land Registry the seeds of 3D Cadastre have been planted since the establishment of the Unified System in 1972. This base was the registering of condominiums, and other special 3D objects. Main Acts, which strongly influence Land Registry, (Act on Surveying and Mapping Activities from 1996, and Act on Land Registry from 1997), have been elaborated for the Land Registry situations in the mid of 90’s. Technical and infrastructure developments during the last 15 years force the change on not only the technical, but on the legal environment, as well. The paper deals with the present situation, the proposed, new legislation and technical solutions in Unified Land Registry, which all of them points to a real 3D Cadastre in Hungary
