Group of Geoinformation Systems
The main research trends are: creation of specialised geographical information systems and databases; use of satellite telemetry methods in ecological investigations; quantitative and qualitative analysis of the structure of Lithuanian land cover, and modelling of the landscape structure using aerial photos and digital elevation model; research on long-term land cover changes and variability of ecosystems; creation of unanimous ecological information system for the Baltic Region.
The group was founded in 2003.
In 2004, the group was confirmed GIS Coordination Centre (HELCOM/ICES) of the Baltic Region.
