Research at the Lab for Geoinformatics and Geovisualization (g2lab) is guided by the following ideas:
.. visualizing spatio-temporal data enables understanding of complex problems and decision making
.. applying task-oriented approaches generates effective and efficient visualizations
.. modeling and communicating uncertainties makes decisions more certain
