WMS The General Bathymetric Chart of the Oceans (GEBCO) consists of an international group of experts who work on the development of a range of bathymetric data sets and products. GEBCO operates under the joint auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. See our web site for more information about GEBCO at https://www.gebco.net/. This service provides access to the GEBCO_2014, in the form of shaded relief imagery as layer 'GEBCO_2014'. It also provides access to imagery based on the Source Identifier (SID) Grid that accompanies the GEBCO_2014 Grid as GEBCO_2014_SID. Please note that GEBCO_2014 Grid has now been superseded, see GEBCO's web site for further information about the latetst release of the GECO grid: www.gebco.net. The GEBCO_2014 Grid is a global grid of elevation data at 30 arc-second intervals. This data set is available as a Web Map Service (WMS) for use as imagery in your applications. The bathymetric portion of the grid was largely generated from a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. However, in areas where they improve on the existing GEBCO Grid, data sets generated by other methods have been included. Further information about the data sets included in the grid can be found in the documentation that accompanies the data set and is available from https://www.gebco.net/data_and_products/historical_data_sets/. Within the GEBCO grid land elevation data is largely taken from the 30 arc-second version of the Shuttle Radar Topography Mission data set (SRTM30). Further details can be found in the data set's documentation. The imagery for land areas in this WMS, north of 60 degrees south, is largely taken from the NASA Blue Marble: Next Generation data set, produced by Reto Stockli, NASA Earth Observatory, the NASA Goddard Space Flight Center (http://earthobservatory.nasa.gov/Features/BlueMarble). For land areas south of 60 degrees south, coastline and ice shelf information is taken from the Scientific Committee on Antarctic Research (SCAR) Antarctic Digital Database coastline dataset (http://www.add.scar.org). The GEBCO_2014 global grid is accompanied by a Source Identifier (SID) grid - this indicates which of the corresponding cells in the GEBCO grid are based on soundings or existing grids and which are interpolated. The SID grid accompanying the GEBCO_2014 Grid is available as a layer in this WMS, GEBCO_2014_SID. GEBCO's first gloabl 30 arc-second interval terrain model was the GEBCO_08 Grid, published in January 2009. The WMS layer generated for the 2010 version of the GEBCO_08 Grid is included as a layer, 'GEBCO_08', within this WMS for users of this existing WMS layer. Information on how to download the GEBCO's grids can be found at https://www.gebco.net/. Please note that GEBCO's grids are mainly deeper water data sets and do not contain detailed bathymetry in shallower water areas. This WMS has been developed by the British Oceanographic Data Centre (BODC) on behalf of the GEBCO community. If imagery from this WMS is included in web sites, reports and digital and printed imagery then we request that the source of the dataset is acknowledged and be of the form 'Imagery reproduced from the GEBCO Grid, version xxxxx, www.gebco.net'. Where 'version xxxxxx' is the appropriate version number of the GEBCO Grid, given in the layer information below.
