2D Bathymetric Maps
2D Bathy Maps
With the 2D module installed and a connection to your depth sounder, you can generate your own bathymetric database in real-time and display it in 2D.
You can select the characteristics of the display: minimum and maximum depth displayed, step between isolines, etc.
A choice of several displays (isolines, plain colors, etc…) allows for quick assessment of the sea floor configuration.
To display data in 2D, click the 2D button
located in the Chart palette. The 2D bathy config palette appears and allows you to configure the 2D bathymetric data that you want to display in the current window. Clicking on the button again turns off the 2D display.
This section provides all the features that allow you to find and display bathymetric data on the chart. You will learn on:
1.How to use the 2D Bathy config palette
2.Displaying type and presence of imported data
3.Setting up the 2D display configuration
4.Choosing a 2D color gradient for the display
5.Choosing a 2D display mode
6.Displaying simultaneous different layers
7.All the bathymetric data are stored in a database, you will also learn in this section how to import different types of data and how to manage this database.

2D Bathy Config Palette
The 2D Bathy config palette can be represented in 2 different ways.
229
MaxSea Operator Manual version 12.6
To switch from the "reduced
Palette" mode to the "full
Palette" mode and vice
versa, click the special Full Palette button :
Reduced Palette
Caution: The " reduced Palette" or " full Palette " mode is not remembered when you leave MaxSea.
The palette is always in " full Palette " mode when you start MaxSea.
"Reduced Palette" description
•Upper left-hand the bathymetric color scale is displayed.
•Below the "2D display mode choice" buttons and pop-up
Button to display / mask isolines.
Button to display / mask depth surface.
Button to display / mask the presence and the type data imported to the 3D data base.
230
2D Bathymetric Maps
MaxSea displays the depth by default, when available the pop-up gives you the possibility to display the ground discrimination track and access the ground discrimination function.
(for more information refer you to the Ground Discrimination chapter)
NB: the Depth option contains DEM, Cmap or User data depth values.
The values Min and Max is reminded, in fact, in the bathymetric color scale. It allows you to know these values even in "reduced Palette" mode.
In the example, one sees according to the palette that the shown isolines is 600 , 800,1000,1200,1400 and 1600m.
"Full Palette" description
Upper right-hand of the Bathy Config palette, there are 3 small pop-up menus to select the interval of the depths on which the display will be based.
However you can directly keyboard the data.
IMPORTANT
if more than 100 isolines is selected to display, a warning is displayed. Otherwise, MaxSea may start to slow down, displaying Hundreds of isolines.

Show/Hide 2D Bathymetric Data on the Chart
Use the 
button to show / hide the 2D bathymetric data displayed on the chart and find quickly where data are localized.
1.Before selecting the button you have to configure parameters for choosing which data you want to display. (see MaxSea options chapter to display the details of your data import)
2.The "Use data type" displayed on chart, depends on which options you have selected.
Example :
Display all Use data type
Display only DEM data
Display only Vector chart data
232
2D Bathymetric Maps
Display only User data
IMPORTANT
If occasional problems may occur when displaying the bathymetric data on the chart, an up-to- date list of common display problems can be found in the Troubleshooting section.
Note: if you forget to select the Use DataType button, the data will not be displayed.
2D Display Configuration
Depth choice
Min = Minimum depth
Max = Maximum depth
Step = Distance in meters between 2 isobathes.
Automatically
The Auto Config button automatically applies optimal display parameters based on the current chart data. Use this button to get an instant 2D view relevant to your current screen display. It is then easy to manually adjust the display to your own preferences.
Manually
For example, if you navigate between 10 and 500 meters, you may wish to view isobathes every 20 meters.
You can use the values suggested in the pop-up or adjust them directly.
233
MaxSea Operator Manual version 12.6
•Configure the "Bathy palette config" like in the example
•Click on the Apply button to see the new display.
The Apply button will activate once you change the parameters. (Your parameter settings will be discarded if you choose not to click the Apply button.)
Note: MaxSea accepts decimal numbers for the depth values (.2, .3, etc.).
2D Color Gradient
There may be times when you want to change the 2D color gradient - for example when there isn't enough contrast between the 2D display and ship track (which is red by default).
To change colors, double-click on the upper left-hand color scale of the 2D palette. The following dialog box appears and gives you five color gradient choices, select one and click on OK.
234
2D Bathymetric Maps
The configuration is simultaneously applied in the 2D palette and in the chart window.
Examples:
Example(1): the 2D color gradient is from blue to red and in this example the ship track is not clearly visible.
Example(2): in this example the ship track appears clearly after you have chosen the blue gradient color.
2D Display Mode Choices
There are three available display modes:
•Isobathes only: to follow a fault line,
235
MaxSea Operator Manual version 12.6
•Depth surface only
•Isobathes and depth surface: for a composite view
236
2D Bathymetric Maps
Overlaying simultaneously several types of data
If a ground discrimination system is connected to MaxSea and the Hardness (E1) or the Roughness (E2) data values are recorded, MaxSea can show the depth data values (in "Isobathes") and the roughness data (in "Depth surface") simultaneously:
This example shows two ways to simultaneously display multiple data types.
237
MaxSea Operator Manual version 12.6
Here the "depth surface" mode is selected to display the depth values and the "Isobathe" mode configuration is selected to display the "Roughness" data.
