Maritime Boundaries Geodatabase: Exclusive Economic Zones (200NM), version 11This dataset builds on previous versions of the world's EEZ. In version 9, the 200 nautical miles outer limit was completely recalculated using a higher resolution coastline as a normal baseline (ESRI Countries 2014) and straight baselines, where available. This dataset consists of two shapefiles: polylines that represent the maritime boundaries of the world's countries, the other one is a polygon layer representing the Exclusive Economic Zone of countries. This dataset also contains digital information about treaties, joint regime, and disputed boundaries.
