Geospatial data (GIS.*)

A set of codelists used to model a vessel flag / data reporting country (typically, referenced by ISO-3 code), as well as several different types of irregular Indian Ocean areas of relevance, such as the main IOTC convention sub-areas, various IO EEZ areas, and some irregular areas of statistical relevance at national or regional level (e.g., I.R. Iran coastal sub-areas, EU PS fleet statistical areas, YFT assessment areas etc.).
The center coordinates and the ocean area in KM2 of each irregular area or regular grid are calculated with respect to the fraction of the theoretical area (potentially overlapping with the mainland) that falls within the IOTC area of competence.
