Hydrographic nodes — Guadeloupe 2009 — BD Carthage

A hydrographic node is a change in water flow. It is always located at the end of an elementary hydrographic section. The hydrographic node class managed by the IGN includes: — confluences, diffluences, springs, mouths and losses of watercourses; — containment dams; — dams over the water; — locks (for passage or refit); — sources and waterfalls of tourist interest. A hydrographic node is located by a geometric top. Some nodes correspond to an outlet of a hydrographic area. The BDCarthage Guadeloupe is maintained by DEAL Guadeloupe. The structure of the database is identical to the metropolitan format.The Carthage Guadeloupe BD is a version validated by the EIS but not by the IGN and therefore problems of incompatibility with IGN referentials can occur (and that an update “officialise” the Carthage BD with IGN validation).
