|Ocean Mapping Projects
Bathymetric data are also used for the preparation of the General Bathymetric Chart of the Oceans (GEBCO), which comprises 18 separate map sheets, covering all oceanic areas. The GEBCO Series is produced jointly by the IHO and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. The 5th Edition of the GEBCO map series was completed in 1982, and its digital equivalent, the GEBCO Digital Atlas (GDA) is available on CD-ROM.
A primary aim of these regional ocean mapping programmes, is the development of a regional series of bathymetric maps at scale 1:1 million, followed by geological/geophysical series.
Regional bathymetric mapping is carried out under the following GEBCO "International Bathymetric Chart" (IBC) projects:
