a compilation of useful databases with download address, documentation and recommandations

Global databases


- Site GEBCO (gridone et GEBCO_08):

    Documentation GEBCO-08 (pdf)

    GEBCO-08 up-to-date version (2010) is available on srv-ecola

    gridone up-to-date version (2008) is available on srv-ecola

    Recommandations: quality is highly variable, most shelves are noisy


    - DBDB-V :

      Download is (presently) not available, some past extractions are available on srv-ecola


      - Smith & Sandwell:

        Documentation :

        The last versions (14.1, 15.1 and 16.1) are available on srv-ecola. Native format is img, it can be manipulated via GMT. To convert the full file into netcdf format::

        img2grd topo_15.1.img -T1 -Gtopo_15.1.grd -R-180/180/-80.738008628/80.738008628 -m1-D

        - Site NOAA:

          Documentation ETOPO-1 (pdf)

          Up-to-date version is available on srv-ecola



          Despite tremendous efforts from data centres, none of the global data set can be considered as being fully satisfactory, and accuracy is highly geographically dependent. From our past experiences, gebco_08 and Smith & Sandwell (release 14) are the most useful. gridone is generally much too smooth (and possibly out-dated), but it can be an advantage for modelers in some shallow areas where bumpy artefacts (quite ubiquitous in data set that contains gravitational or sea level anomalies inversion) can damage numerical flows. As far as we know, etopo-1 is rarely a good choice, except for US and japanese waters.


          Regional databases


            • US waters

          the NOAA distributes a set of coastal databases covering the US waters. NOAA site can be found at:
