DCDB
In 1988, the U.S. National Geophysical Data Centre (NGDC) offered to host and operate a Worldwide digital oceanic bathymetry data center on behalf of the IHO Member States. This led to the official establishment (in June 1990) of the IHO Data Centre for Digital Bathymetry (DCDB). Data provided by the IHO Member States are available for download from the DCDB web site. It is possible to search, view or download all available data using the DCDB Web Map Server and GEODAS interfaces (please see below).
