Where they improve on the existing grid, data sets developed by other methods have been included. The grid is largely based upon a database of shiptrack soundings with interpolation between soundings guided by satellite-derived gravity data. The map is based upon bathymetry data from the GEBCO_08 Grid, version 20100927, a global bathymetric grid with 30 arc-second spacing. 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. "Image reproduced from the GEBCO world map 2014, Creation of the map If imagery is reproduced from the GEBCO world map then we suggest the following form of acknowledgement Please note that because of the size of the files we recommend that they are saved to disk rather than opened from the above links. in GeoTIFF format (445 Mbytes) for the region between 72°N and 72°S.This is the third release of the map and now includes the names of features on the seafloor. The GEBCO world map shows the bathymetry of the world's ocean floor in the form of a shaded relief colour map.
