Research at the Lab for Geoinformatics and Geovisualization (g2lab) is guided by the following propositions:
> 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.
