3D Cadastral Data in The Process of Urban Planning

Abstract

Cadastral data are very important in the process of urban planning. Moreover, cadastral data present a spatial base for urban planning decisions. Over the last few decades, research on 3D cadastres have been performed raising worldwide awareness of the need for 3D cadastral systems. This was driven by the development of new technologies for the acquisition, storage, maintenance, and visualization of 3D data as well as by complex situations in urban areas that cannot be unequivocally registered in 2D based cadastral systems. This paper examines the 3D cadastral data and emphasizes the differences between traditional cadastral data and 3D cadastral data. An overview of 3D cadastral systems was provided, the basic description of 3D cadastre data, and examples of the real situations that traditional cadastral systems cannot handle and unequivocally register. The paper further presents what would be clear benefits for urban planning once the 3D cadastre system is implemented. It is emphasized how important is 3D geometry and data on ownership for underground constructions and utility networks. Conclusions were provided and what needs to be fulfilled to effectively use 3D cadastral data in the process of urban planning.
