Hydrographic regions — Guadeloupe 2009 — BD Carthage

The hydrographic breakdown is the four hierarchical partitions of the French territory carried out according to decreasing hydrographic areas: — hydrographic region (1st order), — hydrographic sector (2nd order), — hydrographic sub-sector (3nd order), — hydrographic area (4nd order). A hydrographic region is divided into a maximum of 10 sectors. The list of hydrographic regions was adopted in Circular No 91-50 of 12 February 1991 but the determination of their limits is the responsibility of the Water Agencies. The BDCarthage Guadeloupe is maintained by DEAL Guadeloupe. The structure of the database is identical to the metropole.The Carthage Guadeloupe BD is a version validated by the EDIS but not by the IGN and therefore problems of incompatibility with IGN REFERENTIELS may arise (and an update “will formalise” the Carthage BD with IGN validation).
