SUMMARY

From national economic point of view, the uniform land registration system operating in Hungary is one of the most important databases of the country. This system has been keeping and maintaining all descriptive (legal) and geometric data, also information on ownership and other rights (e.g. mortgage), land use and land protection relating to all landed properties and other real estates in Hungary in an authorized way and continuously updated status. The cadastral maps integrated into the uniform land registration system show spatial relations and references of rights, facts and other information appearing on the property sheets, serving as a basis of engineering planning for the national economy. The national spatial data infrastructure can be built on this uniform, authorized and public land registration system, in small partial modules, following the EU INSPIRE Directive. The latest development idea is to organize the data into one database (data warehouse) synchronized with the central land office database, and in another one, which serves for the data market and data mining. Consequently, data maintenance and data supply will be separated. This way, through organized centralisation of data, a „round-the-clock ” land office information service can be realized, which will strengthen the data security in Hungary. This will be accessible for citizens through the Central Clients ’ Gate on the Governmental Portal. In the first phase of the long-term “Digital Land Office ” development plan, the central system will only supply data, but it is also the basis of the future electronic case management procedure supported by countrywide uniform forms.
