BACKGROUND OF THE INVENTIONĮarly tide display devices did not have enough memory to store any significant amount of future tide information and therefore they were programmed to calculate the occurrence of high and low tides based on a mathematical algorithm. 20, 2004 incorporated herein by reference in its entirety.

a bottom menu to allow to switch between a graphical or a textual representation of the prediction.This application claims the benefit of U.S.the main station events, with their time, value and description,.NOTE: pay attention about the " Your time" and " Station time" switch that select to which Time Zone you would refer the prediction: the one where the device is set to or the Time Zone of the station. the date selected, where you can move backward (-24 hours) or forward (+24 hours) using the arrows or select a specific date tapping on the date label,.the graph, where you can see the overall tide (or current) behaviour you can move the slider to see the value at a specific time (the green vertical line means NOW),.This page is divided in 5 sections, from top to bottom: Detail pageįrom the tide (or current) icon pop-up described above you can tap on the button and open the Detail page. You can tap on the blue box arrows to move to the previous or next day, or you can tap on the date/time label to select a specific date/time. You will be able to simulate the prediction, along the selected day, moving the slider. Time simulationĬurrent icon you will open a pop-up window like this:Ĭlicking on the left icon you will start a prediction simulation for all the tides and currents icons on the screen. the dark blue and light blue sections of the arrow giving the percentage of the total tidal current (a completely dark blue arrow means Max Flood/Ebb and a completely light blue graph means Slack).Ĭurrent icons could be drawn with some transparency on the map, that means the current prediction is at a certain depth and not on surface (more the depth more the transparency).the small internal cyan icon showing if the current is increasing (pointing in the same direction than the main icon ) or decreasing (pointing to the back of the main arrow ),.the direction of the main arrow showing the actual current direction,.a number (eg 1.9) that represent the speed of the current (in the selected measure of unit: kts/kmh),.NOTE: sometime the number is red, that means it is a negative tide (below the Mean Low Sea Level). when the graph is on the left part of the icon it means is a falling tide,Īnd the dark blue and light blue sections of the graph give the percentage of the total tide (a completely dark blue graph means High tide and a completely light blue graph means Low tide).when the graph is on the right part of the icon it means is a rising tide,.On a tide icon you have a number (eg 0.3) that represent the value of the tide (in the selected unit of measure: feet or meters) and a synthetic representation of the Tide graph where you can see the phase of the tide: for a realtime Tidal current prediction.If you enabled the function the T&C icons will be added (where present) to the map: You can enable/disable the T&C overlay on the map directly from the main Settings page. Other than the typical graph display you can also see the tides and currents representation directly on the map. In Aqua Map you have access to the predictions of more than 6000 Tide and Tidal Current stations in North America and Oceania.
