Currently, the Austrian system for property security of land is based on the land register and the cadastre. These systems are primarily intended to show private relationships and ownership. To ensure orderly development of land, the legislation takes up in the private real property more and more, and so the number of Public-Law Ownership Restrictions arise. For the owners themselves and those who are interested in specific properties, it is important to know the currently valid legal relationships at certain land. If Public-Law Ownership Restrictions should be announced in the land register or cadastre, with high binding and legal certainty, these existing systems do not offer the necessary conditions. In this thesis, the foundations for the realization of a cadastre of Public-Law Ownership restrictions are examined. It is the aim of this system to integrate Public-Law relationships. Here are the most important conditions that the content of the cadastre of Public-Law Ownership restrictions is up to date and complete and that the user gets a high level of legal certainty. For these reasons, legal and organizational foundations, which are necessary for the realization of the Cadastre in Austria, are discussed in this thesis. At the beginning the swiss cadastre of Public-Law Ownership restrictions is explained and it is tried to give a definition of Public-Law Ownership restrictions. Particular attention is also paid to the processes and data management of a future cadastre of Public-Law Ownership restrictions, because a close examination of these objects is essential for a possible future introduction of the cadastre system. At least, the Public-Law Ownership restrictions "Flächenwidmungsplan" and "Denkmalschutz" are examined in detail and a possible integration in the cadastre of Public-Law Ownership restrictions is discussed.
