A lot of data were removed from the xtide-data package because some the UK Hydrographic Office complained that its data were being distributed, and the authors decided to closely examine all data licenses. Only the free ones are left on the xtide-data package, and only thus that can at least be freely distributed are left in the xtide-data-nonfree package. See http://www.flaterco.com/xtide/harmonics_boilerplate.txt I'm afraid that many Canada sites were removed because the Canadian Hydrographic Service (CHS) doesn't give a sufficiently free license (if it gives one at all). AFAIK, The Canadian sites that are left use harmonics independently calculated from freely available data. The harmonics are not from the CHS. I might be tempted to try to obtain from water level data and learn to generate harmonics for other Canadian sites, but my plate is pretty full right now. You can keep using the old xtide-data package from etch : http://packages.debian.org/etch/xtide-data but the XTide author advises that some of that data may have drifted from reality by now. Verify the output with other sources a few times before believing it. Let's downgrade this bug to wishlist for better documentation, okay? Disclaimer : The above details about Canadian data are from memory. I didn't look up the information to refresh my memory so some of the details can be wrong. I speak here as the Debian maintainer for xtide and not in any official capacity as an employee of the Dept. of Fisheies and Oceans. Thanks, -- Peter S.
