XTide downloads

Warning for Windows users

XTide was designed for Unix and X11, not Microsoft Windows.  If you want to try to use it under Windows anyway, there's a precompiled binary for the command-line client, and there are also some ports.  However, these are all supported by their respective maintainers.  Please route support questions accordingly.

Contents

Except for the contrib files that are external links, all of the following can be downloaded by anonymous FTP from ftp://ftp.flaterco.com/xtide/.

• Harmonics files
• libtcd
• XTide
• World Vector Shoreline data
• Contrib packages and patches
• Extras
• For experts only
• Miscellaneous government publications
• Old crap

Harmonics files

All data for the U.S. and associated locales available from the National Ocean Service web site as of 2007-02-07 have been imported.  Stations in Germany, Netherlands, and U.K. are also included.

Data for locations outside of the U.S. are for non-commercial use only!

• Legal notices (please read)
• List of included locations
• Quality assurance information
  • U.S.A.
  • U.K.
  • Germany

You can obtain legacy data for many more locations than are provided by the files above from Bob Kenney's web site.  However, the legacy data are old and their use is not recommended.

For users in the U.S., the only reason to use the legacy data would be to get currents.  Regrettably, harmonic constants for currents are not presently available from the National Ocean Service web site, so they are not included in the latest database.

libtcd source code distribution

• libtcd-2.2.4.tar.bz2, prerequisite for XTide 2.9, tideEditor, tcd-utils, et al.
• New libtcd documentation
• Old libtcd documentation:  Jan Depner, "Format for the Oceanographic and Atmospheric Master Library (OAML) Tide Constituent Database," rev. 2003-06-06
  • PDF format
  • OpenOffice format
  • Notes by DWF

XTide source code distribution

• xtide-2.10.tar.bz2, the current release of XTide.  Requires libtcd.  You also need a harmonics file; see above.

World Vector Shoreline data

World Vector Shoreline data for optional use with XTide 2.5 or newer.  37 MB.  If 37 megs is too much to download, you can download files individually and make do with the lower resolutions.  Find the individual files in ftp://ftp.flaterco.com/xtide/wvs_unpacked/.

These files were published on the National Geophysical Data Center (NGDC) 5-Minute Gridded Global Relief Data CD-ROM (ETOPO5), 1993, and are public domain.  They are available from NOAA at http://www.ngdc.noaa.gov/mgg/global/relief/ETOPO5/BOUNDARY/WVS.  Related information is available at http://www.ngdc.noaa.gov/mgg/fliers/93mgg01.html.  If the files are obtained from NOAA, the filenames must be changed to all lowercase letters to work with XTide.

Contrib packages and patches

• Binary packages:
  Alternative XTide icons contributed by Morten Kjeldgaard.
  Telephone interface:  From NerdVittles, a text-to-speech XTide bot for the Asterisk PBX (via PBX in a Flash) is available here or here.
  WordPress tide prediction plugin by Mir Rodríguez.
  HTML PHP front end to generate an enhanced tide calendar with Hawaiian L10n using a customized pcal 4.11.0 and XTide 2.9.5, by Eric Nichols.
  Joomla component to import tide data from XTide, also by Eric Nichols.
  GSHHS patch—test code to make XTide read Global Self-consistent Hierarchical High-resolution Shorelines instead of WVS files (DWF).

  Extras

  • tideEditor-1.4.1.tar.bz2, a GUI editor for Tide Constituent Database (TCD) files.  Requires libtcd and Qt 3.x.
  • tcd-utils-20080820.tar.bz2, command-line tools for converting Tide Constituent Database (TCD) files to and from other formats.  Requires libtcd.

  For experts only

  Software:

  • congen-1.6.tar.bz2.  The Congen package includes libcongen, a C++ library for generating the speeds, equilibrium arguments, and node factors of tidal constituents, and congen, a command-line program for generating the speeds, equilibrium arguments, and node factors of tidal constituents using text files for input and output.  This package requires a case-sensitive file system to build correctly.
    • README
    • libcongen header file
  • harmgen-3.1.tar.bz2, program to derive harmonic constants from water level observations.  Requires Congen 1.6 and Octave.
    • README
    • harmgen-extras-20080523.tar.bz2, data converters and stuff that are in a perpetual state of disrepair.
  • harmbase2-20071228.tar.bz2, harmonic constant management system.  Requires Postgres 8.2.3, Congen 1.6, libtcd and libdstr.

  Other materials:

  • seasonal_corrections.xls, a spreadsheet for approximating Sa and Ssa from Admiralty-style seasonal corrections.  Contributed by Art Najjar of NAVO.
  • NAVO.xls, spreadsheet of constituent definitions contributed by Art Najjar of NAVO.
  • congen_input.txt, input file for congen.  Last update 2004-08-16.

  See also the IHO list of constituents in the next section.

  Old crap

  • xtide-1.6.2.tar.gz, the final, frozen revision of XTide 1.  No longer supported.
  • I no longer support the Java applets for XTide.  There will be no Java support in XTide 2.  However, the unmaintained, unsupported Java applets can still be downloaded from xtide_java_jdk1.0.tar.gz.  The JDK 1.1 update, xtide_java_jdk1.1.tar.gz, was never finished.
  • harmbase_2004-08-09.tar.gz, old harmonic constant management system.  Requires Postgres (see README).
  • converters.tar.gz, software to convert (1) From Ed Wallner's TIDES 4 format to XTide's harmonics file format; (2) From XTide format to TIDES 4 format; (3) From the NOS data file format to XTide format.  These converters were obsoleted by Harmbase, which incorporates better conversions.  You also need to download the mapfile to use these.  Last revision 1997-08-09.
  • map.txt, map file for use with the preceding conversion software.  Last revision 2001-01-15.
