Creation of the map
Work on the creation of the GEBCO world map began as a laboratory workshop project of the Nippon Foundation/GEBCO Training Project at the Center for Coastal and Ocean Mapping of the University of New Hampshire, USA.
The map is based upon bathymetry data from the GEBCO_08 Grid, version 20100927, a global bathymetric grid with 30 arc-second spacing. The grid is largely based upon a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. Where they improve on the existing grid, data sets developed by other methods have been included.
This release is an updated version of the 2013 world map (second release). It now includes the names of undersea features.
The land imagery is taken from the US National Aeronautics and Space Administration’s (NASA) Blue Marble data set. The coastline is taken from the World Vector Shoreline.
The first release of the GEBCO world map was published in 2007 and was based on bathymetry data from the GEBCO One Minute Grid.
