Abstract
A graphic tide indicator system in which time intervals between a plurality of corrective tides are stored, the temporal position in the current time interval is determined, and a visual display is employed to display the relative water depth.
Claims21
An animated graphic tidal indicator system, comprising:
- means for storing time intervals between a plurality of consecutive tides;
- means for determining a plurality of temporal positions, each indicative of a relative water depth, in a current time interval based on the actual time of day;
- and
- visual display means, responsive to said means for determining, for displaying a plurality of sequential animated scenes representing variations of said relative water depth between tidal extremes in said time interval.
1 more element
An animated graphic tidal indicator system, comprising:
- means for storing time intervals between a plurality of consecutive tidal events, for a plurality of different coastal locations;
- means for providing a choice between said different coastal locations, including a default coastal location if no choice is provided;
- means for determining the current date and time;
- and
- means for displaying a plurality of sequential animated scenes representing the current tidal state for the chosen or default coastal location.

An animated graphic tidal indicator system, comprising:
- means for storing time intervals between and heights of a plurality of consecutive tides;
- means for determining a current temporal position in a current time interval;
- means, responsive to said means for determining, and said means for storing, for calculating approximate current water depth;
- and
- means for displaying an animated scene depicting said calculated approximate water depth.
