Attribute table
Exclusive Economic Zones
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) |
Extended Continental Shelves
The table below describes the semantics of each field in the ECS dataset attribute table.
| Attribute name | Description | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| MRGID MRGID_ECS | 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: ‘ECS CLCS Recommendation, ‘ECS CLCS Submission’, ‘ECS DOALOS Deposit’, ‘ECS Joint CLCS Recommendation’, ‘ECS Joint CLCS Submission’, ‘ECS Joint DOALOS Deposit’, ‘ECS Overlapping claim’, ‘ECS Non-UNCLOS Claim’. |
||||||||
| TERRITORY1 | Specific land area which directly relates to the polygon. For example: for ECSs bordering a country, the territory is the country. For ECSs surrounding an island, the territory is the island itself (e.g. French Extended Continental Shelf (Kerguelen) (CLCS Recommendation)). |
||||||||
| 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 TERRITORYn SOVEREIGNn |
For joint regimes and overlapping claims, multiple states can claim a territory (and associated ECS) or sea area. In this case, the different territories and their sovereign state are listed in the attribute table. For sea areas, the territories are the territories that claim the ECS. For example (Overlapping claim: Denmark (Faeroe) (CLCS Submission) / Ireland (CLCS Submission)):
