attribute NC_GLOBAL references String Information on the data set is available from the GEBCO project web pages: http://www.gebco.net/data_and_products/gridded_bathymetry_data/
attribute NC_GLOBAL source String The bathymetric portion of the GEBCO_2014 Grid was largely developed from a database of ship track soundings with interpolation between soundings guided by satellite-derived gravity data. In areas where they improve on this existing base grid, data sets developed by other methods are included. Recognising the importance of local expertise when building a global bathymetric model, GEBCO have been working with regional mapping groups to improve the existing GEBCO grid. Details about the development of the grid and the data sets included can be found in the documentation that accompanies the data set. With the exception of polar regions, land data are based on the 1-km averages of topography derived from version 2.0 of the US Geological Survey SRTM30 gridded digital elevation model data product, created with data from the US National Aeronautics and Space Administration (NASA) Shuttle Radar Topography Mission. For the Arctic region north of 64N the GEBCO grid is based on the International Bathymetric Chart of the Arctic Ocean (IBCAO) v3. This data set uses land data taken largely from the Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) data set. Over Greenland the approximately 2000 by 2000 m resolution Digital Elevation Model (DEM) published by Ekholm (1996) is used. For the Southern Ocean area, south of 60S, land data are taken from Bedmap2 data set as included in the International Bathymetric Chart of the Southern Ocean (IBCSO). The grid is accompanied by a Source Identifier grid, which identifies which grid cells are based on soundings or existing grids and which have been interpolated. The grid uses the convention that depths are negative.
