**About the Editors**

**Rohan Bennett** is an Associate Professor in Information Systems with the Swinburne Business School, Melbourne, Australia; and a Geodetic Advisor with Netherlands Kadaster. He specializes in spatial information systems and land information management. He has previously held posts with the University of Twente (NL), Kadaster International (NL), and University of Melbourne (AU). He holds degrees in Science, Engineering, and a Ph.D. in Land Administration from the University of Melbourne. He led and worked on the Euro Commission H2020 project 'its4land' from 2016–17 and is currently involved with project work on the application of blockchain, UAVs, and auto feature extraction in land rights management.

**Peter van Oosterom** is a Professor of GIS Technology at the Faculty of Architecture and the Built Environment. The Chair concentrates on spatial information infrastructure. A central component is durable geoinformation that can be shared and re-used, based on joint definitions of data sets and services. Proceeding from technology and technology development, the Chair contributes to the realization of a spatial data infrastructure based on vario scale spatiotemporal 2D–5D models and processes for application areas like cadastre and real-time GIS. Van Oosterom has contributed to developments in 3D geometry and data modeling, the results of which are now part of the Oracle spatial Database Management System. Together with the Netherlands Cadastre, van Oosterom introduced a worldwide standard for the land administration domain model (ISO 19152).

**Christiaan Lemmen** is a Full Professor at ITC, the Faculty of Geo-information Science and Earth Observation, University of Twente, the Netherlands (part-time). He is also a Geodetic Advisor with Kadaster International, the international branch of the Netherlands Cadastre, Land Registry and Mapping Agency. Christiaan is an Editor of the International Standard for the Land Administration Domain Model (LADM), published as ISO – 19152. The second edition of LADM is under development since 2018. He is a Co-Chair of the Land Administration Domain Working Group of the Open GeoSpatial Consortium. Christiaan is the Director of the OICRF, which is the Office International du Cadastre et du Regime Foncier (the international Office for Cadastre and Land ´ Records), a documentation center for land administration, and a permanent institution of the International Federation of Surveyors (FIG). He holds a Ph.D. in Land Administration from Delft University of Technology, The Netherlands.

**Mila Koeva** is an Assistant Professor working in 3D Land Information. She holds a Ph.D. in 3D modeling in architectural photogrammetry from the University of Architecture, Civil Engineering and Geodesy in Sofia. She also holds MSc. degrees in Engineering (Geodesy) from the same institution, obtained in 2001. Her main areas of expertise include 3D modeling and visualization, 3D Cadastre, 3D Land Information, UAV, digital photogrammetry, image processing, producing large-scale topographic, and cadastral maps, GIS, application of satellite imagery for updating cadastral information among others. Currently, she is also a Co-chair of ISPRS WG IV/10 "Advanced Geospatial Applications for Smart Cities and Regions" and a Contributing Editor for GIM International. In 2017, she was ranked as one of the TOP 3 teachers of ITC 2016–2017. From 2017–2020, she was the Project Coordinator of its4land, a multidisciplinary European Commission Horizon 2020 project, involving 8 academic and private-sector partners and 6 countries in Europe and Africa.
