    Cadastral system as the 'where' component of a property rights system is central to effective land markets, land use and sustainable development. The foundation of any cadastral system, the relationship between people and land, is constantly altering and cadastral systems as well have evolved over time in response to these changes. The focus of this dissertation is on understanding the cadastral system dynamism, and more specifically, the potential future changes of cadastral systems. Empirically the main focus is on the Finnish cadastral system that presents an example of a mature cadastral system with long traditions on registration of land related interests. This dissertation suggests that the future of cadastral systems should be approached from a holistic and systemic perspective and, therefore, integrates concepts and knowledge from the disciplines of futures studies and socio-technical transition studies. The dissertation adopts a mixed method approach with a greater emphasis on qualitative research methods. Literary sources, a Delphi questionnaire, interviews, and focus group meetings are used in data collection. This dissertation provides a refined and revised understanding of what drives change in the context of land administration and how the mature cadastral systems might develop in the future. Exploration of emerging issues of change reveals the increasing awareness of the multi-purpose role of cadastral systems, as the identified issues range from technology-oriented ones to political, economic, environmental, and social issues. Overall, the findings suggest that the future of cadastral systems is a complex issue that cannot be reduced to individual technologies or innovations. Rather, this dissertation argues that more emphasis should be put on the institutional foundations, i.e., on the elements that coordinate and stabilise the established systems when the goal is to detect distinctively alternative configurations for cadastral systems. The academic value of this thesis is in bridging the gap between land administration literature and futures studies and socio-technical transition studies, and in creating comprehensive understanding of cadastral system dynamism. The base of evidence obtained in this research also provides new and fresh insights to actors of land administration domain.

    Terrestrial, Earth-fixed, reference frames are fundamental, but often unnoticeable, components for modern societies. Today, regional terrestrial reference frames are created and maintained by the measurement of continuously operating Global Navigation Satellite System (GNSS) reference stations. In Fennoscandia, glacial isostatic adjustment (GIA) causes deformation, also known as postglacial rebound, decreasing the accuracy of national static reference frames referring to the European Terrestrial Reference System 1989 (ETRS89). Considering the deformation is thus a necessity to accurately transform coordinates from the International Terrestrial Reference Frame (ITRF) to national ETRS89 realisations such as EUREF-FIN in Finland. This dissertation focused on estimating densified reference frame realisations in the global reference frames for the Nordic and Baltic countries. The work was carried out in the GNSS Analysis Centre project of the Nordic Geodetic Commission (NKG). It builds on eight local analysis centres, one in each country, processing its sub-net. The emphasis of the dissertation was on developing methods for combination of the sub-nets, analysis of the time series, and estimating a multi-year position and velocity solution, including uncertainties of the station velocities. The results showed that the sub-net solutions were consistent with the combined solution within 1–2 mm. The distribution of the GNSS processing into local sub-nets thus strengthened the daily solutions due to the redundantly processed reference stations. The station-wise position time series were analysed for offsets both manually and with the developed automatic approach with a 74 % success rate in respect to the manual interpretation. Station velocities were estimated for approximately 270 stations from daily position solutions. The lengths of time series varied between 3 and 20 years. Uncertainty levels of 0.10, 0.10, and 0.25 mm/y for the north, east, and up components respectively were reached with 10 years of data for more than 90 % of stations. The detailed understanding of the GNSS time series in the Nordic and Baltic countries will enhance the quality of the European and global terrestrial reference frame realisations, because some of the stations contribute with the same data to those solutions. The densified reference frame solutions will be utilised in the maintenance of the national geodetic reference frames, including deformation modelling and the development of the accurate coordinate transformations. This will ultimately extend the lifetime of the national reference frames like EUREF-FIN.
