The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

Limites des secteurs de la RDC. Le fichier est issu de la digitalisation par UNOCHA et UNDP de l’atlas de l’organisation administrative de la RDC réalisé par le père Léon de Saint Moulin. Lorsque les limites de secteurs sont définies par un cours d’eau, la géométrie a été partagée. La toponymie et la codification ont été validées par l’INS. Boundaries of sectors of the Democratic Republic of Congo (RDC). This dataset is a digitization of UNOCHA and UNDP of the administraive organization atlas for the RDC produced by leon de Saint Moulin. The boundaries of these sectors are defined by waterways, geometry and and subdivisions. The toponomy and codification were validated by the INS.

Aucune base de données ne disposait du positionnement numérique des ports. Les ports fluviaux correspondent à des noeuds des [axe_hydro]. Ils ont été positionnés par comparaison entre le fichier des localités transmis par la MONUC et, soit la carte des ports transmis par la RVF, soit le listing des ports transmis par la SNCC. En l’absence de ville ou de village portant le nom du port, le noeud a été créé en référence au PK transmis par la SNCC ou la RVF. Le positionnement des ports fluviaux a été fait au sein de l’agence UNJLC de Kinshasa en 2006. No database gives a numerical position of ports. The fluvial ports correspond to nodes on the hydrologic axes. They are positioned by comparisons between the local data...
