The IWR Tide Tool makes use of standard astronomical tidal prediction techniques and databases of tidal stations. The Tide Tool generates tidal height and current information for primary and secondary tidal stations as well as statistics on tidal availability, for example the cumulative distribution function of tidal availability at a location. A geographical interface making use of Google Earth™ allows for simple identification of tidal stations, and supports creation of secondary tidal stations for use in HarborSym. Output can be generated and saved in standard spreadsheet formats.
The latest release of the IWR Tide Tool, version 188.8.131.52, is available for download.
