RASTER FILES
Access to raster data files only on actual CD-ROM
There are four types of raster files available on this CD-ROM. Associated with each raster file type are three different resolution grid files; these include 3 arc-second, 9 arc-second and 30 arc-second. The one exception is that there is no ASCII XYZ 3 arc-second file due to size limitations. Latitudes are geodetic latitudes according to WGS-84.
To download the GMT/NetCDF files directly to your hard drive first set the MIME type to application/netcdf, the file suffix to grd, and click on save to disk. Please refer to your browser's documentation for help on how to do this. For the other three file types hold your mouse button down on the link and choose the save link as option.
