Hi Kwan, re: topography/bathymetry AREA files on SSEC web site > I just came across the site for the first time and have not given it a try > yet. OK. re: > But I noticed that the world maps posted there do not show any ocean > topography. So I suppose the McIDAS files do not contain bathymetry data? The description for the Land Elevation topo.gz file indicates that they do contain bathymetry information: "The RAW values are as follows: 0-8752 Height above sea-level 55537 Ocean >55537 Height below sea-level = (RAW - 65536)" Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
