DESCRIPTION                                                             
     Abstract:     
         The General Bathymetric Chart of the Oceans (GEBCO) is now available
     as the GEBCO Digital Atlas (GDA) on CD-ROM.  It is published by the
     British Oceanographic Data Centre (BODC) on behalf of the
     Intergovernmental Oceanographic Commission (IOC) of UNESCO and the
     International Hydrographic Organization (IHO).  It includes a
     seamless, global, digital set of the GEBCO basic contours (200m, 500m,
     and at 500m intervals thereafter) with contours at intermediate
     depths also included in some areas, where available.  The CD-ROM is
     accompanied by a floppy disk containing the GDA Software Interface and
     an extensive Supporting Volume describing the activites of GEBCO and
     providing a User Guide to the software.
     
     Contents of the CD-ROM:
     
      Digitized bathymetric contours, coastlines and trackline control
     from the GEBCO Fifth Edition published at a scale of 1:10 million
     
      Digitized bathymetric contours and coastlines from the First
     Edition of the International Bathymetric Chart of the Mediterranean
     published at a scale of 1:1 million
     
      A set of digital global coastlines, based on the US Defense Mapping
     Agency's World Vector Shoreline, at a range of scales from 1:43
     million to 1:250,000
     
      A trackline inventory of the digital echo-sounding data held at the
     IHO Data Centre for Digital Bathymetry as of December 1993
     
      A digital set of geographically referenced feature names including
     the IHO/IOC Gazetteer of Geographical Names of Undersea Features and a
     specially prepared list of oceanic islands
     
      A digital version of the Third Edition of the Echo-sounding
     Correction Tables
     
     The GDA Software Interface:
     
     The GDA Software Interface provides a powerful and user friendly tool
     kit which includes facilities for selecting, interrogating,
     visualizing, overlaying and exporting data from the GDA.  It has a
     very low learning overhead enabling the user to zoom into any
     geographic area of interest at will.  Contours, coastlines and
     tracklines can be displayed using a choice of 5 projections, and the names
     of undersea features and oceanic islands can be queried interactively.
     Screen images can be directed to the user's printer or stored as a
     PCX or GEM image for use in desktop publishing software.  Selected
     contours, coastlines and tracklines can be exported in vector form as
     labelled streams of geographic coordinates, either in DXF format or as
     a simple flat ASCII file.
     
     To run the digital Atlas you will need:
     
     An IBM PC (or compatible) with a VGA color display, a CD-ROM drive, a
     3.5" floppy disk drive, and a hard disk with at least one Megabyte of
     free space in which to install and run the software.  The software is
     designed to run under DOS 3.0 or later, and requires about 500K of free
     RAM.  A mouse (Microsoft compatible) is highly desirable but not
     essential.  The contours, coastlines and tracklines (except for the
     World Vector Shoreline) are also stored on the CD-ROM in a simple
     ASCII file format directly accessible to the user without the need to
     use the interface software.
     
     The price of a single copy of the GEBCO Digital Atlas (including
     CD-ROM, software interface and supporting volume) is 230 British
     Pounds (plus 40.25 British Pounds VAT applicable to orders from the
     European Union).  A special discount price of 99 British Pounds (plus
     17.32 British Pounds VAT if applicable) may be claimed by
     organizations whose primary mission is academic research or education
     and by organizations routinely supplying their echo-sounding data to
     the IHO Data Centre for Digital Bathymetry.  Above prices include
     postage and packing.
