----------------------------Original message---------------------------- While we're on the subject of bathymetry, I'm looking for a digital product with decent shallow water bathymetry. Ideally, global, gridded every 30 arcsecs, down to 200 meters depth. My guess is that no such beast exists, but there has to be something better than the awful data in ETOPO5. Any thoughts? Also, has anyone seen a bathymetric chart of the Caspian Sea with more than two or three contours in it? Thanks in advance. -Frank E. Reed Clockwork Software, Inc. http://www.clockwk.com
