Laboratory of geographic information systems

The laboratory is dedicated for research and development of methods for acquisition, processing, analysis and visualisation of geospatial data, such as:

  • optimizing strategies for 3D data collection in high resolution,
  • integrating 3D geospatial data,
  • spatial interpolation for digital modelling of landscape surfaces,
  • modelling of spatially distributed natural phenomena, for example, solar irradiation, surface temperature, overland water flow, soil erosion;
  • optimizing geospatial methods by paralelization;
  • interactive modelling and visualisation by physical 3D model of landscape and image projection (Tangible landscape);
  • developing open-source tools GIS tools.

Researchers:

  • Dr. Michal Gallay
  • prof. Jaroslav Hofierka (leader)
  • Dr. Ján Kaňuk
  • prof. Vladimír Sedlák

Lab administrator: doc. RNDr. Ján Kaňuk, PhD.
