Fs2004 Srtm Global Terrain Map
Global ocean & land terrain modelsGEBCO’s gridded bathymetric data set, the GEBCO2019 grid, is a global terrain model for ocean and land at 15 arc-second intervals. More.The Grid is available to download:. as a global file in netCDF format. for user-defined areas in: netCDF, Esri ASCII raster or GeoTiff formatsDownload the global grid files.

Add your selection to the basket and repeat the process as required. Once you are happy with your selection(s) view the basket and checkout your request to start file preparation. You will be directed to the British Oceanographic Data Centre's (BODC) web site for the data download procedure.

You can return to GEBCO's web site once this procedure is complete.Please note that the map display layers are based on the previous GEBCO grid, GEBCO2014. It is intended to update these layers in the near future.Use the '+' button in the top right-hand corner of the map to select to display the GEBCO Source Identifier (SID) Grid. It is best viewed at a zoomed in level to appreciate the detail in the data set.
Depending on the size of your area selection, or during busy periods, data preparation may take a while. Our file generator service will email you when the data are ready for collection. Dataset errataAlthough every care is taken during the development of the GEBCO bathymetric grids, errors are occasionally reported. Reported issues can be viewed on our. Note on vertical datum and GEBCO's gridsGEBCO's global elevation models are generated by the assimilation of heterogeneous data types assuming all of them to be referred to mean sea level. However, in some shallow water areas, the grids include data from sources having a vertical datum other than mean sea level.
We are working to understand how best to fully assimilate these data. Find out more.
