Global

Bathymetry and Elevation

The General Bathymetric Chart of the Oceans (GEBCO) Digital Atlas (GDA) contains global bathymetric data sets, consisting of the latest versions of GEBCO’s global gridded bathymetric data sets; global bathymetric contour and accompanying trackline control data sets; bathymetric contours and coastlines from the First Edition of the International Bathymetric Chart of the Mediterranean (IBCM); a set of digital global coastlines based on the World Vector Shoreline data set (coastlines south of 60S have been removed) at a range of scales from 1:43 million to 1:250,000; the SCAR coastline of Antarctica (version 3.0) at a range of scales from 1:30 million to 1:250,000; and a digital set of geographically referenced feature names including the International Hydrographic Organization (IHO)/Intergovernmental Oceanographic Commission (IOC) Gazetteer of Geographic Names of Undersea Features. The GEBCO dataset has global coverage and was first released in 1994. The contents of the GDA are updated periodically to include new versions of GEBCO’s bathymetric grids. The GDA is distributed on DVD and includes full documentation and a software interface for viewing and accessing the data sets.
