prof. Jaroslav HOFIERKA
Principal Investigator

Professor Jaroslav Hofierka provides strategic direction for the project. Within the project he is responsible for 3D data processing and development of new 3D spatial methods and implementation in open-source GIS. Currently, he also serves as a director of the Institute of Geography, Faculty of Science, Pavol Jozef Safarik University in Kosice. He specializes in geographic information science, spatial interpolation, digital terrain models and solar radiation modeling.



assoc. prof. Zdenko HOCHMUTH

Zdenko Hochmuth specilizes on karst and cave research. He graduated in Physical and Regional Geography at Commenius University in Bratislava. His research interests are karst geomorphology  and land cover in the karst areas. He was awarded Candidate of Science (equv. PhD degree) at the Slovak Academy of Sciences in Bratislava and the assistant-professor degree in Physical geography at Commenius University. Zdenko is a longtime active speleologist, he participated at many expeditions in Slovakia and in the world (Alps, Balkans, Venezuela, Mexico). He is currently working in the field of prolongational speleology, speleocartography, karst hydrography and speleoclimatology. He is the author of monographs focused on slovak caves and karst.





Dušan Barabas is focused on assessment of hydrological conditions of the research area in relation to climate change, water balance, river channel morphometry and morphology. He also works on landscape ecology issues. Dušan graduated in 1986 at the Comenius University in Bratislava, Slovakia with the Master of Science degree in Geography and Cartography. After that he worked on a doctoral project titled “The dynamics of hydrological processes in the depressed areas of the Eastern Slovakia lowlands ") at the same university where he was awarded the degree of Candidate of Science (equiv. PhD.) in 1994. Currently, Dušan works as a lecturer at the Institute of Geography, University of Pavol Jozef Safarik University in Košice, Slovakia.



Dr. Michal GALLAY

Michal Gallay specilizes in digital terrain modelling and analysis using various height data sources and methods of spatial prediction. Recently he focuses on acquisition and modelling with laser scanning data (LiDAR), therefore his main role in the SPATIAL3D project is to define the parameters of data collection and classification and to optimize the methods for deriving a digital surface model (cave, terrain). Michal achieved his BSc. in Geography and Cartography (2003) and MSc. in Physical Geography and Geoecology (2005) at Commenius University in Bratislava, Slovakia. He was awarded PhD. at the School of Geography, Archaeology and Palaeoecology at Queen's University Belfast, UK. Currently, Michal works as a lecturer of GIScience at the Institute of Geography, Pavol Jozef Šafárik University in Košice, Slovakia. He is also a deputy for research and foreign relations at the Institute.






His research interests are in 3-D geospatial information, 3-D data collection, processing and modelling 3-D landscape phenomena, and 3-D visualisation. He has graduated as a teacher of geography and physical education at the University of Prešov, Slovakia in 2006 and has obtained his PhD degree on ‘Modeling of solar distribution in urban landscape’ in 2009 at the University of Prešov, Slovakia. Currently, Ján works as an assistant-professor at Pavol Jozef Šafárik University in Košice (since 2011).
Within the project he participates on the data collection and processing from laser scanning, GNSS measurements as well as other measurements of the selected landscape components. He is responsible for 3D model development, visualizations, testing and validation of new 3D tools in GRASS GIS.




Alena Petrvalská specilizes in karst geomorphology, geomorphological mapping, caves and cave mapping and karst areas morphometry. Recently, she works in the field of karst springs geochemistry and karst hydrogeology in Slovak karst area. She studied geography and biology on the Natural Sciences Faculty at University of P.J. Šafárik in Košice (MSc, 2006) and dissertation at Comenius University in Bratislava with specialization on physical geography and geoecology (PhD, 2011) with thesis "Karst geomorphology of Jasov plateau".
Withing the project she is responsible of Čertova diera mapping and cave morphology research with  focus on discharge analyses of subsurface cave stream and cave climate data collecting.
