Hydrographic Areas — Martinique 2004 — BD Carthage

The hydrographic division is l' all of the four hierarchical partitions of the French territory made according to decreasing hydrographic areas: — hydrographic region (1st order), — hydrographic sector (2nd order), — hydrographic subsector (3 rd order), — hydrographic area (4th order). A hydrographic region is divided according to a maximum of 10 sectors. The list of hydrographic regions was established in Circular No. 91-50 of 12 February 1991 but the determination of their boundaries is under the responsibility of the Water Agencies. The geometry is close to the BDTopo IGN which was used for its realisation.The BDCarthage Réunion is maintained by the DEAL Réunion.The BD Carthage Réunion is a version validated by the SIE but not by the \#x27;IGN and that therefore problems of incompatibility with IGN referentials can occur (and that#x27; an update &officialiseraquot; the Carthage comic with IGN validation). __Origin__ The Martinique BDCarthage is maintained by DEAL Martinique. __Partner organisations__ Ash, DEAL Martinique __Links annexes__ * [see documentation on Sandre website](http://www.sandre.eaufrance.fr/?urn=urn:sandre:dictionnaire:ETH::entite:ZoneHydro:ressource:latest:::html) * [see Dictionary & Hydrographic Reference (ETH)" on the Sandre website](http://www.sandre.eaufrance.fr/?urn=urn:sandre:notice:dictionnaire::theme:ETH:ressource:latest:::html) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/f18ab3f18a2c96b419d329060e6111cbf707138d)
