In Aqua Map you have access to the predictions of more than 6000 Tide and Tidal Current stations in North America and Oceania. Other than the typical graph display you can also see the tides and currents representation directly on the map.
You can enable/disable the T&C overlay on the map directly from the main Settings page.
Icons on map
If you enabled the function the T&C icons will be added (where present) to the map:
- for a realtime Tide prediction.
- for a realtime Tidal current prediction.
Tide icons
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:
- when the graph is on the right part of the icon it means is a rising tide,
- when the graph is on the left part of the icon it means is a falling tide,
and 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).
NOTE: sometime the number is red, that means it is a negative tide (below the Mean Low Sea Level).
Tidal current icons
On a tidal current icon you have:
- a number (eg 1.9) that represent the speed of the current (in the selected measure of unit: kts/kmh),
- the direction of the main arrow showing the actual current direction,
- 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 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).
Current 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).
Time simulation
current icon you will open a pop-up window like this:
Clicking on the left icon you will start a prediction simulation for all the tides and currents icons on the screen.
You will be able to simulate the prediction, along the selected day, moving the slider.
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.
Detail page
From the tide (or current) icon pop-up described above you can tap on the button and open the Detail page.
This page is divided in 5 sections, from top to bottom:
- the name of the station,
- 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),
- 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,
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 main station events, with their time, value and description,
- a bottom menu to allow to switch between a graphical or a textual representation of the prediction.
