The pre-stored wave height data refers to the height of sea waves, and the pre-stored wave direction data refers to the direction of the sea waves, namely the phase position of the sea waves.
Step S102, receiving wave selection area data sent by a client, wherein the wave selection area data comprise the longitude and latitude of waves;
here, the user selects on a GIS (Geographic Information System) map of the client as required to obtain sea wave selection area data, where the sea wave selection area data includes the longitude and latitude of the sea wave, and the longitude and latitude of the sea wave are the longitude of the sea wave and the latitude of the sea wave.
