Description
The hydrographic division is the set of four hierarchical partitions of the French territory made according to decreasing hydrographic areas:
- hydrographic region (1st order),
- hydrographic sector (2nd order),
- hydrographic subsector (3rd order),
- hydrographic zone (4th order).
A sector shall be divided into a maximum of 10 sub-sectors and a sub-sector shall be divided into a maximum of 10 hydrographic zones.
The geometry is close to the BDTopo IGN that was used for its realization.The BDCarthage Mayotte is maintained by the DEAL Mayotte.The BD Carthage Mayotte is a version validated by the SIE but not by the IGN and that therefore problems of incompatibility with IGN referentials can occur (and that an update will "officialize" the BD Carthage with the IGN validation).
