The GEBCO_2014 Grid
The GEBCO_2014 Grid is classified as a historical Gebco dataset with a spatial resolution of 30 arc seconds.
Originally published in 2014, last updated in April 2015. The data set is largely based on a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. Where they improve on this model, data sets generated from other methods are included.
The grid is accompanied by a Source Identifier Grid (SID). This indicates if the corresponding cells in the GEBCO_2014 Grid are based on soundings, pre-generated grids or interpolation.
