WEB-BASED VISUAL EXPLORATION AND ERROR DETECTION IN LARGE DATA SETS: ANTARCTIC ICEBERG TRACKING DATA AS A CASE
Polar iceberg data are – amongst others – used by scientists who are interested in complex phenomena like global warming, climate change and changing habitats. Other main users of the data are organisations and individuals involved in navigation and engineering that need to take iceberg positions an...
