3d Cadastre – A Motivation and Recent Developments of Technical Aspects

Abstract

The paper gives motivation for considering a 3D cadastre based on the registration of 3D spatial units, i.e. the (bounded) amount of space to which a person is entitled by means of real right. This approach gives a better insight into the registration of rights and restrictions. In 2012 the international standard ISO 19152 Land Administration Domain Model (LADM) was approved. The LADM is a conceptual model, its purpose is not to replace the existing systems, but rather to provide a formal language for describing them, so that their similarities and differences can be better understood and it also offers the concepts for the modelling of 3D spatial units. Based on the LADM, country profiles can then be defined and extended. The paper further explores the technical aspects of a 3D cadastre, especially summarizing the main findings and challenges in 3D information modelling and 3D spatial databases for a 3D cadastre.

Transformation of 3D geospatial data into CityGML – a case of Prague

“…Figure 15 displays the information about owner of the selected 3D object; in this case, it was Charles Bridge. The proposed solution could be used, for example, for building the 3D cadastre (Janečka, 2018).…”
