Another great map from one of my favourite contemporary cartographers John Nelson. This time John took data from Anti-shipping Activity Messages database published by the National Geospatial-Intelligence Agency and mapped 8,000 incidents registered over the past 40 years.
The map is based on data aggregated to glorious hexagons showing a heat map of the nautical pirate activity. The high-level map allows us to quickly identify the highest risk areas around the coasts of Malaysia, Somalia and Nigeria. What I like about it is that it shows you a beautiful piece of cartography but in the web version of the map, the hexagons expand the individual incidents at closer scales, which makes it also a useful tool for more in-depth analysis. Really cool!
What’s even more awesome, John shared a tutorial on how he created the map using ArcGIS Pro! Check it out:
