Due to its 200 years existence the Austrian land cadastre has become an Austrian cultural asset nowadays. Since the establishment of a stable cadastre in 1817 by the Land Tax Act, there is a more or less precisely documented evidence of the cadastre. In particular, attention was directed to document any change within the cadastre to keep it up to date. Therefore, it theoretically has to be possible to historically trace back the property boundaries and determine the ownership structure for any date. In the course of this diploma thesis an attempt is made to restore the original states / borders in the cadastre. For this purpose, sharing plans, site plans and other relevant technical documentation as well as old map sheets (deutsch: Mappenblätter) are used. The central questions to be answered in this thesis are the following: - Is such a reconstruction of boundaries possible and where may problems occur? - Do gaps between boundaries occur during recovery? What are their magnitude and causes? This work begins with a theoretical part, explaining the definition and the content of the Austrian land cadastre as well as its history. In particular, the evidence and the significant changes in the cadastral system are discussed. Furthermore, a separate chapter will deal with the Digital Cadastral Map as well as its development, goals, and content. Subsequently, the documentation of the changes in the Digital Cadastral Map will be described in detail, as it contains essential information for the practical part of this work. The final section of the theoretical part deals with the control point field (deutsch: Festpunktfeld) and discusses its development and changes. The practical part, which was conducted in a small test area in the cadastral community (deutsch: Katastralgemeinde) Strasserfeld in Lower Austria, covers the return of the borders for the last 20 years. The results show that such a return is possible in principle. However there have also been problems here and there, especially with graphical boundaries. Therefore there is an additional chapter, describing the challenges in the return process in detail and explaining the result of the comparison between the Digital Cadastral Map of 1997 and the returned boundaries. Finally, it is discussed which changes would have to be made in the documentation of the cadastre to enable a better evidence and an easier return of the borders.
