The research focusses on methods and techniques to integrate data from different sources and dimensions (2D, 3D, Time). The data are offered via a variety of map representations in multi-functional visual (online) environments that allow exploration and data analysis. To justify the solutions produced, usability research is an integral part of the activities.

Geographic data is characterized by a locational, attribute and temporal component. The time component can be a typical indicator of change of all sorts. For instance, movement data holds information about where the movement took place (the path), what was moving (the object), and especially when it was moving (the time frame). Examples are travel time between cities, the daily trips of commuters, or the possible average speed along a path etc.

Remote sensing image repositories are the fastest growing archives of spatio-temporal information. This leads to large time-series that geoscientists need to explore and understand. Effective exploratory tools are urgently needed to handle the large data sets efficiently. Common application areas that require such tools are, amongst others: climate change and environmental monitoring studies, hazard analysis, [...]
