资源简介：
The GEBCO world map shows the shape and depth of the global ocean floor as a shaded relief map. This is the third release of the map and now includes the names of features on the sea floor from the IHO-IOC GEBCO Gazetteer of Undersea Feature Names. The map is based upon bathymetry data from the GEBCO_08 Grid, version 20100927, a global bathymetric grid with 30 arc-second spacing. 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.
