Definition:

Tide - the periodic rise and fall of the surface of the sea, due principally to the gravitational interactio n between moon, sun and earth. (adopted from IHO Dictionary, S-32, 5th Edition, 5429)

Predicted tidal heights may be calculated using time and height differences with respect to a reference port (and associated tidal predictions).

Remarks:

The object 'tide - non-harmonic prediction' encodes information for use when predicting times and heights for high and low waters by non-harmonic methods.

The supplier of any parameters must be consulted on how to use data provided using this object class, and which calculation algorithms to use with the data.

Distinction: tide - harmonic prediction; tide - time series;
