3D property research from a legal perspective

This article investigates and discusses 3D property research, as evidenced by conference papers and other publications written in English, to analyze the distribution of interest areas and the occurrence of legal aspects and trends within 3D property research occurring between 2001 and 2011. A total of 156 publications on 3D property were examined. The publications were classified in four different categories, which represent different aspects of 3D property: legal, technical, registration and organizational. More 3D property research has been conducted on technical aspects and registration than legal aspects. In the legal category, most studies addressed national legislation and the practical use of (national) legislation. The authors believe that further fundamental legal research on 3D property is needed. The quantity of research could be increased, for example, by promoting international discussion and increasing the number of comparative legal studies on 3D property rights. Additional and more focused attention should be given to international matters, such as comparative studies on the use of 3D property concepts, the development of (international) 3D property terminology and cooperation between 3D property unit owners.

Integration of Legal Aspects in 3D Cadastral Systems

This article continues a research on the feasibility of BIM for 3D cadastre in unified building models, presented in. It describes problems and solutions concerning interaction between BIM and the registration and visualisation of legal 3D property information. BIM and legal 3D property are two seemingly different domains, and there is a lack of BIM-3D property research in relation to technical and registration issues. The article therefore focuses on possibilities and difficulties of addressing legal interests i.e. rights, restrictions and responsibilities in land. A Swedish case study is used to describe the use of 3D property formation and registration in Sweden, and how it might be possible to achieve a more integrated, standard based registration of legal boundaries and physical buildings. The results emphasize how BIM and 3D property domains can interact to serve the needs for effective information handling by e.g. importing 3D cadastral boundaries into BIM as basis for decision-making or to use BIM as input in the 3D cadastral formation process.

Motives for Participation in Formal Standardisation Processes for Geographic Information: An Empirical Study in Sweden

The purpose of this article is to investigate the personal motives for participation in formal standardization processes for geographic information. The method involved interviewing members of technical committees at the Swedish Standards Institute, SIS. The results are that the majority of the interviewees are very motivated in their work and they think their participation is well-financed by their organizations allocating them to a technical committee. The main motives are to contribute to development of society and be at the forefront of development. However, this article also shows that several members participating in this study felt that they do not have sufficient time for working with tasks related to their technical committees. Their daily work in their respective organizations often has higher priority in relation to standardization work. This contrasts with the organizational goals of the participating organizations and may slow down the development of standards and other publications due to lack of resources.
