I just looked and it provides tide data according to certain stations around the world. For your geographic coordinate, you'd have to find the nearest reporting station and calculate any differences (hours and minutes plus or minus from that station). The author indicates that some foreign tables may not be totally accurate and the U.S. stations are based on National Ocean Service documents. Available from: Edward P. Wallner 32 Barney Hill Rd. Wayland, MA 01778-3602 (508) 358-7938 * version 2.17 It would be helpful to hear from someone at the U.S. Naval Observatory (the Nautical Almanac) where I understand certain data bases are available. I would also recommend the British Admiralty Tide Tables; yes I know it's paper and not glitzy, but it's always worked for me. - Paul Leverenz Scripps Institution of Oceanography ----------------------------------------------------------------- : Tue, 15 Aug 1995 04:42:28 -0400 (EDT) : [log in to unmask] : Re: tides prediction software "Is anyone aware of a software program that, provided with latitude, longitude, date and time, will provide tide prediction for that given area? " There are a number of shareware packages that will do this. The online location with the largest selection that I am aware of is the Sailing Forum on Compuserve, but I am sure some of these are available at shareware FTP sites on the net. Incidentally, the prediction isn't exactly latitude-longitude based. Tides depend critically on ocean basins and coastlines so you have to select a city or other coastal point from a list of standard stations. But once that's done, it's easy to get reasonably accurate tide predictions for any date and time in the future. -FER ------------------------------------------------------------- : Tue, 15 Aug 1995 10:06:19 EDT : [log in to unmask] : RE: tides prediction software There is a freeware call "TIDES" available from Edward Wallner 32 Barney Hill Rd Wayland MA 3602 508- 358-7938 The date on the documentation was 1993 so it is reasonably current. I hope it does the job. ME Folkoff [log in to unmask]
