GEBCO Grid display
The GEBCO grid display software allows you to view and access data from GEBCO's gridded bathymetric data sets
- the GEBCO One Minute Grid — a global one arc-minute grid
- the GEBCO_08 Grid — a global 30 arc-second grid
The software is available to download under licence and can be used with either or both gridded data sets. Please note that the software is designed for use with the complete, global data files. It will not work with subsets of the full global data sets.
It provides the means for displaying the data and accessing the data in netCDF and also in simple ASCII formats, including one suitable for conversion to a raster file which can be used with ESRI ArcGIS products.
The software has been developed by BODC to run on a PC running Microsoft Windows 95 or later. It is controlled by a series of drop-down menus and toolbar buttons. The current version is 2.13 and was released in April 2010.

Reported bug on 31 July 2012
A bug has been reported in the GEBCO grid display software that affects the export of the GEBCO_08 Grid and GEBCO_08 SID grid. In some limited cases when the selected geographic region for export is defined as a fraction of a whole degree, then the exported data value at each grid point has been shifted (in longitude) by one grid cell, i.e. 30 arc-seconds, from its correct value.
We apologise for any inconvenience caused and are working to fix this bug. We will make a revised version of the software available as soon as possible.
In the meantime, we recommend that users of the GEBCO grid display software select geographic regions for export at whole degree intervals rather than as fractions of a degree.
