Abstract
ABSTRACT Increasing population in urban areas and limitations of suitable lands for developing houses and urban infrastructure have led to the vertical development in cities. However, these developments are managed by a cadastral system which is mainly two-dimensional and cannot efficiently represent Rights, Restrictions, and Responsibilities (RRRs) in complex scenarios. In fact, a three-dimensional cadastre is required for efficiently registering and representing RRRs. In this paper, a 3D proximity analysis was proposed and implemented to determine RRRs and associated easement rights in non-topology-based data structures. This method can be used to investigate the surrounding spaces of a subject apartment unit or storage in a high-rise. The performance of the developed method was evaluated in a large complex high-rise in Tehran, Iran. The results confirmed that the proposed method can correctly identify the neighbor spaces in complex scenarios.
Highlights
Population growth and shortage of land are common challenges in urban areas that have led to increased development of high-rises and complex buildings above and below the ground surface
This study aimed to develop an innovative method for a 3D proximity analysis to detect neighbor Restrictions and Responsibilities (RRRs) in a 3D space in the domain of land adminis tration
This paper focuses on developing a method for 3D proximity analysis to identify neighbor RRRs around objects such as apart ment units and storages
Summary
Population growth and shortage of land are common challenges in urban areas that have led to increased development of high-rises and complex buildings above and below the ground surface. Mapping the 3D world into a 2D model causes various limitations and inefficiencies (Shojaei 2014; Zhao, Yan, and Zhang 2018). It is very hard for the public to understand their rights by looking at 2D cadastral plans. There can be restrictions or responsibilities between the property objects and the right-holder(s) (van Oosterom et al 2006). This emphasizes the importance of having an efficient system for recording Rights, Restrictions and Responsibilities (RRRs)
