Area

The Area table includes geographic names given for a specific area of investigations. Area names attribute to the CAMPAIGN and EVENT tables, the latter appears in the metaheader of a data set. To define an area, open the Area table in 4D and click on New. During the import of events, new area names used in the event list will automaticaly be added to the area list.

Names of areas and localities are not standardized yet and thus should be used for retrievals with care. Some standardization will be implemented in the future by using the Limits of oceans and seas as defined by the International Hydrographic Organization, Monaco (IHO). For continents above sea level, the names of all countries will be included. While importing new events, an algorithms will automaticaly set the relations to the area table by using the IHO-defined limits of seas and the borders of countries. This will allow retrievals of data in a specific area given as a countries name or an IHO definition of an ocean/sea.
