Attribute table
The table below describes the semantics of each field in the EEZ dataset attribute table.
| Attribute name | Description | ||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| MRGID MRGID_EEZ | Marine Regions Geographic Identifier of the polygon feature. Unique, persistent and resolvable identifier used in the Marine Regions gazetteer. |
||||||||||||||||
| GEONAME | Name of the polygon feature. | ||||||||||||||||
| POL_TYPE | Type of polygon area. Possible values: ‘200NM’, ‘Joint regime’, ‘Overlapping claim’. |
||||||||||||||||
| TERRITORY1 | Specific land area which directly relates to the polygon. For example: for EEZs bordering a country, the territory is the country. For EEZs surrounding an island, the territory is the island itself (e.g. Portuguese Exclusive Economic Zone (Madeira)). |
||||||||||||||||
| MRGID_TER1 | MRGID for the territory | ||||||||||||||||
| ISO_TER1 | ISO3 code for the territory | ||||||||||||||||
| UN_TER1 | UN code (M49 Country code) for the territory | ||||||||||||||||
| SOVEREIGN1 | State that has jurisdiction over the territory. For example: for Madeira this is Portugal. |
||||||||||||||||
| MRGID_SOV1 | MRGID for the sovereign | ||||||||||||||||
| ISO_SOV1 | ISO3 code for the sovereign | ||||||||||||||||
| UN_SOV1 | UN code (M49 Country code) for the sovereign | ||||||||||||||||
| TERRITORY2 SOVEREIGN2 TERRITORY3 SOVEREIGN3 |
For joint regimes and overlapping claims, multiple states can claim a territory (and associated EEZ) or sea area. In this case, the different territories and their sovereign state are listed in the attribute table. For disputed islands/rocks, the territories refer to the islands/rocks/land that are claimed, so in this case the attribute values for TERRITORY1 and TERRITORY2 (and TERRITORY3) will be identical. For example (Overlapping claim Falkland / Malvinas Islands: UK / Argentina):
For sea areas, the territories are the territories that claim the EEZ. For example (Overlapping claim: Puerto Rico / Dominican Republic):
Exception: Overlapping claim South China Sea, as there are more than three states claiming this area, not all claiming parties are included in the attribute table. |

| AREA_KM2 | Area of polygon in square kilometers, calculated in PostGIS by casting the geometry to geography | ||||||||||||||||
| X_1 | Centroid longitude of polygon, calculated in PostGIS (EPSG:4326) | ||||||||||||||||
| Y_1 | Centroid latitude of polygon, calculated in PostGIS (EPSG:4326) |
