The topic of the master's thesis is related to the establishment of a multi-purpose cadastre, especially in terms of upgrading cadastral contents with the data on legal regimes on land. Based on the guidelines from abroad, as well as the specifics of the land cadastre and other spatial data in Slovenia, we have developed a method of linking and harmonising the data of the graphical subsystem of the land cadastre with the data about legal regimes on land. The method was tested in selected study areas with the so-called numerical cadastre (cadastral community 31 Kramarovci and cadastral community 108 Nemčavci), where the quality of the common graphical data layer of the land cadastre was first analysed, and then the graphical data layer of the land cadastre was linked to the graphical data layer on land use. Both data layers were joined by attributes at the level of the land parcel and boundary points of land parcels. As a result, we have shown the layer on land use directly in the land cadastre and compared the result with the international guidelines on a multi-purpose cadastre. In the conclusions, we analysed the possibilities of further development of the proposed method of linking graphical and attribute data on land from various data sources.
