Kurzfassung
Für die Erstellung des Katasters in Polen werden möglichst aktuelle Daten benötigt, die durch verschiedene Methoden gewonnen werden können. Unter anderem werden vielfach auch noch die Mappenblätter des Österreichischen Katasters verwendet, besonders in ländlichen Gegenden und Wäldern. Diese Mappenblätter stammen aus der Zeit, als sich Österreich noch über Teilgebiete des heutigen Polens erstreckte. Diese österreichischen Katasterdaten werden auch noch für andere Aufgaben gerne verwendet, wie etwa bei Grenzstreitigkeiten, aber auch für aktuelle Vermessungsaufgaben. Daraus lässt sich schließen, dass diese Daten aus historischen Zeiten auch in anderen Gebieten, die damals zu Österreich gehörten, verwendet werden könnten.

Abstract
The real estate cadastre in Poland is created step by step based on a modernization process of the grounds and buildings register. In order to create the real estate cadastre, accurate, reliable, and updated boundary data are requested. These data can be obtained by means of various methods and sources. One of these methods, frequently used in the context of crops and forests, is a cartographic method by using Austrian cadastral maps produced many years ago in the former Galizia, being a part of the southern-eastern Poland’s territory. These maps can also serve for other surveying tasks like delimitations, subdivisions, and regulation of the legal status of real estate. Note that the Austrian cadastral documentation is still used in the southern part of Poland for various surveying task. Using the former Austrian documentation needs some knowledge on cadastre and surveying and also particular experience of the surveyors. Frequently, surveyors get some doubts when they want to use the former Austrian cadastral maps. The reason for this is that the maps were prepared by graphic methods using plane table field surveying with low accuracy. Former Austrian cadastral documentation, especially the cadastral map, may be fully used for legal aspects, where real estate boundaries play a very important role. The usefulness of the cadastral map for various surveying tasks is evident [4]. Moreover, it offers a chance for the surveyor to avoid possible wrong steps. As described in the paper, the old Austrian cadastral documentation can still be used even in contemporary surveying; probably not only in Poland but also in those European countries which belonged to the Austrian Empire for many years.
