Rapid economic and social development over the last decade has led to many changes in the way space is managed. The dynamically developing cities, complex infrastructure, vertical spatial division, as well as overlapping ownership rights (in 2D terms) resulted in an increase in the demand for the creation of modern space management systems. The aim of the work is an attempt to answer the question concerning the possibility of using a modern real estate cadastre system. The research method used is case study. The method was supported by an analysis of the literature in the field of land and building records and the use of GIS tools in network analyses. The subject of research is the use of data on building interiors. The task was carried out using the available GIS tools. The method of utilising graphic data presented in this article goes beyond the current cadastre functions and can be used, for example, to find a way inside a building.
