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...

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...

Use of geographic classification/coding systems
Alternatively, a dataset may be geo-referenced using a reference geographic classification and coding system (e.g. FAO Major area codes, grid cell codes).

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...

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...
