“Interactive visual analytics of large, heterogeneous time-dependent, geo-referenced data is still a challenging problem. On the one hand, visual analytics methods are not yet established in science context such as climate research. On the other hand, the combined application of interactive methods provided by visualization and geographic information systems and of automated mining methods is still hampered for non-expert users. As a solution, this paper presents an interactive tool for the analysis of extreme events in heterogeneous climate data sets. To support extreme event detection and comparison, it provides interactive extreme definition and parallel calculation, an interactive map linked with a sortable table of extreme events with their properties and a variety of mapping opportunities. The tool integrates ensemble data of different grid types and time scales and is adaptable to different user groups and computing resources.”
