Reproducible Workflow for Cartography – Migrants Deaths in the Mediterranean

Abstract. As any scientific production, maps must be disputed and debated. The implementation of reproducible processes based on free software and open data is essential. In this paper, we demonstrate that this objective can be achieved in the R software ecosystem. In our demonstration, we propose a set of cartographic visualizations based on the example of dead and missing migrants in the Mediterranean over the period 2014–2018. Each representation focuses on one aspect of the phenomenon and the R code used is available. We argue that this multi-visualization contributes to bring new knowledge on the migration debate at European borders and aims at illustrating its geographical complexity.
