 Total food supply: There are various ways of defining supply and, in fact, various concepts are in use. The elements involved are production, imports, exports and changes in stocks (increases or decreases). There is no doubt that production, imports and... More

 Population: Refers to the present-in-area de facto population, i.e. includes all persons physically present within the geographical boundaries of countries. In general, the population data used are three-year averages of the mid-year estimates published for each country by the Population... More

 Per capita supply: Data under this category indicate the per capita food fish supplies available for human consumption during a given reference period. It is derived by dividing total food supply by the population. More

 In the context of fisheries data, geographic coordinates will consist of pairs of (x,y) numerical values handled in the spatial reference system considered (refer spatial reference system). If needed, these pairs may be extended to include a third dimension with... More

 Geographic coordinates WKT format In Method 3 above, the recommended format for handling coordinates is the OGC Well-Known-Text format (WKT). Whatever the geometric shape, WKT provides a simple string representation of the geometry. In that way, a single column is... More

 Use of Degrees-Minutes-Seconds (DMS) In the case of handling geographic coordinates in official reports and publications, the geographic coordinates can be enumerated using the Degrees-Minutes-Seconds (DMS) notation. This notation is generally used in the legal context where the DMS appears to... More

 Geographic classification systems A geographic classification system can be defined as a way of grouping and organizing geographic references (reference points, lines or areas) to be used as reference data for geo-referencing statistical datasets. To facilitate its use, a geographic classification... More

  Grid classification systems: System defined by a regular geo-referenced grid characterized by a maximum geographic extent or scale (global, regional, local) a grid unit/cell shape (e.g. square, rectangle) a grid resolution (e.g. 1 x 1degree, 5 x 5... More
