Analysis
The team pored through the sequential challenges that migrants face while travelling to and through Europe. These were rendered as a sinuous flow map atop an interactive 3D scene with descriptive annotations for each obstacle.
The static maps used elsewhere in the story illustrate the origin/destination nature of refugees in both diaspora maps and proportional symbol maps. These were rendered in ArcGIS Desktop.
ArcGIS Desktop was used to analyze satellite imagery captured at different dates, detecting human-made surfaces for an estimate of refugee camp growth over time.
