Members of the programme group rewrote their freely available Relief Visualisation Toolbox into an open-source Python library and created a QGIS plugin and raster functions for ArcGIS Pro and ArcGIS online. RVT allows simple computations of advanced visualisation techniques of high-resolution elevation models. The toolbox and visualisation methods have been presented at several international scientific conferences with great success and are used in scientific institutions, universities and professional companies involved in lidar data interpretation throughout Europe and elsewhere, from the USA and Brazil to China and Australia. It is now used as a standard by heritage agencies and national survey offices. The relevance of the toolbox manifests itself in nearly 6000 downloads of the QGIS plugin alone in the first three months, in more than 360 references to the supporting paper (Zakšek et al. 2011), and in the encouraging feedback received by the authors. The implemented techniques, some of which were elaborated by the team (Kokalj and Hesse, 2017; Kokalj and Somrak, 2019), improve visual interpretation and help in automatic recognition of archaeological features. Many, if not most, studies dealing with machine learning in archaeology use RVT for data preprocessing, as evidenced by scientific citations. RVT and documentation are available at https://rvt-py.readthedocs.io/.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 44438829Societal and technological development, together with rapid urbanization, has contributed to the growing complexity of land use. The doctoral thesis focuses on the development of the real property cadasters, which represent one of the fundamental elements for the management of the territory. Traditional land cadastral systems, based on 2D-models of real property units, have limited capabilities for modelling and spatial delineations of rights, restrictions, and responsibilities (RRR). Particularly in an urban environment, there is an increasing requirement for the vertical delineation of the space and 3D modelling of real property units to which RRRs are related. First, the concept of a multipurpose 3D cadastral model was developed, following the LADM international standard for land administration domain and linked to standards for spatial data (IFC, CityGML, IndoorGML). This linking enables the usage of 3D-cadastral data in other domains. Based on the analysis of the existing 2D cadastral data on buildings, we assessed data usability for 3D modelling based on the developed concept. We developed the process for obtaining the indoor connectivity graph based on the extraction of topological relationships between 3D geometries of indoor spaces aiming to contribute to the multifunctionality of cadastral systems (e.g., for indoor navigation). The lack of 3D cadastral datasets is addressed by procedural modelling, which provides the simulation of large-scale 3D cadastral datasets. The simulated dataset allows the execution and evaluation of 3D spatial analyses. Our research has proved that properly structured 3D-cadastral data could be used for applications beyond the land administration domain.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 61788419Members of the research programme group are actively involved as members of the editorial board and as reviewers of the journal Geodetski vestnik, the main journal in the field of geodesy and geoinformatics in Slovenia. Anka Lisec has been editor-in-chief since 2014. Geodetski vestnik has been publishing continuously since 1956 and bringing together a wide range of papers on research, theory and professional practice in geodesy, surveying, geoinformatics, remote sensing and land management. It is an interdisciplinary journal concerned with technical, social, economic, political, legal, physical and planning aspects of geodesy, surveying, real estate management and spatial planning. By publishing the content of various but always high-quality contributions, the journal has exceeded its professional impact in the field of geodesy and is becoming more and more interesting for reading and publishing for other scientific and professional fields. Over the past decade, the international visibility of Geodetski vestnik has risen, thus becoming an important platform for publishing and sharing the latest research and professional achievements in the fields of geodesy, geoinformation, Earth observation and spatial planning.
C.04 Editorial board of an international magazine
COBISS.SI-ID: 5091842Within the invited three-month guest visit, a member of the program group, Anka Lisec, was actively involved in pedagogical and research work at the Technical University of Munich, Germany (germ. Technische Universität München (TUM), Ingenieurfakultät Bau Geo Umwelt, Munich, from 2019: Fakultät für Luftfahrt, Raumfahrt und Geodäsie). In addition to lectures (36 hours), she also participated in indirect pedagogical work and research activities. Among other things, she participated in the preparation of study materials for lectures and seminars, including e-learning materials, research in a group led by Prof. Dr. Walter de Vries (TU Munich, Germany) focusing in the fields of land administration, spatial data infrastructure and spatial data to support decision-making. In addition, she was involved in workshops and other activities of groups at the faculty working in the field of geoinformation and remote sensing, which has contributed to strengthening cooperation with researchers at TUM.
B.04 Guest lecture
COBISS.SI-ID: 43385859Krištof Oštir is the Slovenian delegate to the Data Operations Scientific and Technical Advisory Group (DOSTAG) of the European Space Agency. Within DOSTAG, he is working on defining technical solutions for the next generation of European Earth observation satellites, including those of the Copernicus programme. He co-decides on data storage, data access policy and data access policy. He influences short- and long-term strategic decisions on satellite observation, global and local initiatives and monitors the implementation of projects in this field. DOSTAG is the highest expert body of the Programme Board for Earth Observation (PB-EO), who coordinates European and national Earth observation activities and makes recommendations to the ESA Council on future programmes.
