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_2025 Grid in the form of a flat image layer 'GEBCO_2025_2' and as a shaded relief image layer, 'GEBCO_2025'. Layer 'GEBCO_2025_3' shows those pixels that are based on measured data (largely ship-track data). Areas based on interpolation are set to black. The layer 'GEBCO_2025_SUB_ICE_TOPO' provides shaded relief imagery for a version of the GEBCO Grid that includes under-ice topography/bathymetry information for Greenland and Antarctica. The layer 'GEBCO_2025_2_SUB_ICE_TOPO' provides a flat image layer for a version of the GEBCO Grid that includes under-ice topography/bathymetry information for Greenland and Antarctica. The GEBCO Grid is accompanied by a source data Type Identifier (TID) grid - this indicates the type of data that the corresponding cells in the GEBCO grid are based on. 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.
