VLIZ Marine Regions

Auxiliary shapes for some small-island countries use processed data from Flanders Marine Institute (VLIZ), “Maritime Boundaries and Exclusive Economic Zones (200NM), version 12” (2023, World EEZ v12).

The source dataset is licensed under Creative Commons Attribution 4.0 International. Pitatto Map processes the data into auxiliary puzzle shapes that make small countries easier to find and handle.
