Ivan Razumović – Project Manager.
Ivan Razumović is an associate professor at the Chair of Analysis and Processing of Geodetic Measurements of the University of Zagreb Faculty of Geodesy. He received his PhD in 2014 with a dissertation entitled The analysis of high accuracy transformation as a basis for the transformation of height reference systems. The areas of his scientific research are largely related to the reference coordinate systems, transformation models and the coordinate transformation of high accuracy. He actively participated in the realization of several scientific and scientific-professional projects related to height reference systems and the transformation of height data.
Ivka Kljajić
Ivka Kljajić is an associate professor at the Chair of Geoinformation of the University of Zagreb Faculty of Geodesy. The areas of her scientific research are digital cartography and geoinformation systems, visualization of spatial data and analysis of cartographic representations from different periods. She actively participated in the realization of several scientific and scientific-professional projects.
Blaženka Bukač
Blaženka Bukač is a senior assistant at the Chair of Analysis and Processing of Geodetic Measurements of the University of Zagreb Faculty of Geodesy. Her scientific interest is primarily related to the height component of reference systems, computational data processing and the quality of geo-data. She received her PhD in 2025 with a dissertation dealing with the realization and analyses of the relationship between Croatian and European vertical reference systems and the creation of the corresponding transformation models.
Ivan Ljubičić
Ivan Ljubičić has been an assistant at the Chair of Land Surveying of the University of Zagreb Faculty of Geodesy since 2022. His activities in the implementation of the project are primarily related to the collection, preparation and analysis of available benchmark data and their transformation from the analogue to digital form.
