Migrant boat mini challenge award: Analysis summary a geo-temporal analysis of the migrant boat dataset

The SPADAC team used various visual analytics tools and methods to find geo-temporal patterns of migration from a Caribbean island from 2005-2007. In this paper, we describe the tools and methods used in the analysis. These methods included generating temporal variograms, dendrograms, and proportionally weighted migration maps, using tools such as the R statistical software package and Signature Analysttrade. We found that there is a significant positive space-time correlation with the boat encounters (especially the landings), with a migratory shift further away from the point of departure over time.
