The purpose of this research was to theoretically and empirically explore the success factors in cadastral parcel boundary settlements. Our focus was to study the role of landowners in boundary settlements and dispute management. The issue of landowners’ involvement is highly topical and complex, as the number of disputes stemming from indeterminate landowners’ roles in managing cadastral boundaries and indeterminate roles of the land surveyor as the mediator are considerable. These disputes can be a heavy burden for the country and society as a whole. Our basic research question was very widely set so that the model of success factors of boundary settlements following land cadastre data would go beyond the geodetic and legal framework and would also cover socio-psychological factors. In the literature, this topic is still not addressed, although there are several scientific questions related to it, the focus being on the integration of sociological and psychological factors into the field of spatial management. Based on the opinions of authorised land surveyors, we found for the case of Slovenia that the success of boundary settlement is, along with engineering and property aspects, also influenced by socio-psychological factors. The following factors were found to be essential: previously marked boundaries, preliminary analysis, clear explanation, surveyor’s expertise and communication skills, neighbourly relations between landowners, (psychological) attachment to land, and other personality traits of landowners. Generally, it was found that the surveying procedure and the land surveyor are the most important factors of success in boundary settlements, closely followed by the landowner, while the land data (cadastral data) is the least important factor. We also found that the land surveyor influences the landowner and how the factors related to the landowner will reflect upon the success of the boundary settlement this confirmed that the land surveyor and the landowner are the most important factors of success in cadastral parcel boundary settlements.

he paper focuses on approaches to the registration of real property rights in the case of underground or subwaytunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, andSweden. The authors conducted analysis on the registration of rights to subway tunnels in the chosen countries,including its effectiveness in ensuring appropriate property rights to construct and exploit tunnels. Special at-tention was given to limitations related to the lack of legal provisions vertically dividing space, i.e. into layers,and referring to the ownership right to the layers. Benefits which might be achieved by the introduction of a 3Dreal property subdivision were pointed out. The analysis of the available data concerning the geometry ofsubway tunnels in particular countries was presented. The authors tried to answer the question whether theaccessible data concerning the geometry of subway tunnels allows to generate a 3D geospatial model of aconstructed object, and to specify the space which should be determined as a 3D parcel in the 3D real propertycadastre, for the purpose of registering property rights for the object (the tunne The paper focuses on approaches to the registration of real property rights in the case of underground or subway tunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, and Sweden.

Despite the rapid development of indoor spatial data acquisition technology, there are currently no solutions that enable large-scale indoor spatial data acquisition due to several limiting factors that characterize the indoor space. This fact, together with the rapidly growing need for indoor models, is the main motivation for our research. The focus is on the study of the appropriateness of existing cadastral data for 3D indoor modelling. Within the study, a framework for 3D indoor modelling has been developed, comprising a chain of processes, starting from initial cadastral data and ending with the OGC IndoorGML compliant document. The process chain is divided into three parts, which are described individually and supported by UML activity diagrams. The Slovenian Building Cadastre data represents the basis for the framework design and data assessment. The IndoorGML standard is used for final outputs, as it provides a standardized data model for the representation and exchange of indoor spatial information designed for indoor navigation and location-based services. The data storage options using a spatially enabled database are presented for storing 2D and 3D geometries. The stored data enables fully automatic IndoorGML document generation on request, while also taking advantage of all spatial database functionalities. The proposed approach is software independent and can be implemented with various spatially enabled software packages. In addition to 3D indoor data modelling, the framework represents a comprehensive method for assessing the usability of input data for the purpose of 3D indoor modelling. The assessment is done for the case of the Slovenian Building Cadastre. The assessment of the cadastral data suitability for 3D indoor modelling can be used for decisions regarding future steps towards a multi-purpose 3D real property cadastre. The presented concept can be applied in many countries worldwide that have a similar condominium registration system.
