The current three-dimensionally (3D) delimited property units are in most countries registered using two-dimensional (2D) documentation and textual descriptions. This approach has limitations if used for representing the actual extent of complicated 3D property units, in particular in city centers. 3D digital models such as building information model (BIM) and 3D geographic information system (GIS) could be utilized for accurate identification of property units, better representation of cadastral boundaries, and detailed visualization of complex buildings. To facilitate this, several requirements need to be identified considering organizational, legal, and technical aspects. In this study, we formulate these requirements and then develop a framework for integration of 3D cadastre and 3D digital models. The aim of this paper is that cadastral information stored based on the land administration domain model (LADM) are integrated with BIM on building level for accurate representation of legal boundaries and with GIS on city level for visualization of 3D cadastre in urban environments. The framework is implemented and evaluated against the requirements in a practical case study in Sweden. The conclusion is that the integration of the cadastral information and BIM/GIS is possible on both conceptual level and data level which will facilitate that organizations dealing with cadastral information (cadastral units), BIM models (architecture, engineering, and construction companies), and GIS (surveying units on e.g., municipality level) can exchange information; this facilitates better representation and visualization of 3D cadastral boundaries.

The concept of 3D cadastre is widespread internationally and part of many nations’ legal infrastructure. Since the publication of a literature survey on 3D cadastre research by Paulsson and Paasch in 2013, there has been a considerable amount of research output and activities in regard to 3D cadastre, which led us to believe that a new investigation of 3D cadastre publications could be of interest. The aim of this study is to analyze the development in 3D cadastre research during the years 2012–2020, focusing on the legal perspective of 3D property. A classification was made into main groups, legal, technical, registration and organizational, also investigating the occurrence of sub-themes such as visualization, BIM and standardization. The results of other literature studies on 3D cadastre research were compared with the outcome of this study. The number of identified publications during the analyzed years was 530. The study showed that the number of publications on legal topics has increased, but in relation to the other groups is still rather low. The 3D cadastre research community could benefit from the inclusion of the legal perspective in publications from other main groups, along with an increased focus on international comparative studies.

Land use, land resource demands, and landscape management practices are linked to many of the environmental, climatic, and socio-economic challenges faced by contemporary society. The study focuses on a comparative analysis of the experience of the land resource management (LRM); thus, the study aims respond to how the land-related resources are managed, what policy instruments support it, and what improvements would promote the sustainable management of these resources. Exploring LRM policies in selected countries, the experience of three Baltic countries and two other countries under the jurisdiction of continental Europe was analyzed, and their comparison was made based on qualitative research methodology. Based on the study’s results, the most important comparative characteristics of LRM policies are discussed. The findings of the study in selected countries provide recommendations for improving the institutional framework related to LRM. However, the outcome encourages a transfer of the research experience to other jurisdictions.
