Visual Analysis of Spatio-Temporal Event Predictions: Investigating the Spread Dynamics of Invasive Species

Invasive species are a major cause of ecological damage and commercial losses. A current problem spreading in North America Europe is the vinegar fly Drosophila suzukii. Unlike other Drosophila, it infests non-rotting healthy fruits therefore concern to fruit growers, such as vintners. Consequently, large amounts data about occurrence D. suzukii have been collected recent years. However, there lack interactive methods investigate this data. We employ ensemble-based classification predict areas susceptible bring them into spatio-temporal context using maps glyph-based visualizations. Following information-seeking mantra, we provide visual analysis system Drosophigator for event predictions, enabling investigation spread dynamics invasive species. demonstrate usefulness our approach three use cases an evaluation with more than 30 domain experts.
