A comparative analysis of high-rise building models as a data source for multidimensional cadastre

The paper presents a problem related to the limitations of the current form of cadastre used in Poland – the two-dimensional cadastre, which is often insufficient for technological developments. The problem was presented by means of a comparative analysis of six selected high-rise buildings in Warsaw, which are characterised by complex solid geometry: Rondo 1, Skysawa, Złota 44, Central Tower, Forest and LIM Centre. The introduction discusses the limitations of the two-dimensional cadastre, as well as the opportunities presented by a multipurpose cadastre, which, thanks to integration with GIS systems and BIM technology, might be a revolution in the Polish cadastral system. In the analytical part, two models of each analysed high-rise building were created in Revit using the data available in the national Land and Building Register (EGiB) and the available data on the actual building to present the inaccuracies of the two-dimensional cadastre in more detail. The urban indicators calculated according to the Land and Building Register were also compared with the actual indicators, confirming that the cadastre in its current form is insufficient for a reliable depiction of reality.
