2D Bathymetric Maps

Here the "isobathe" mode configuration is selected to display the depth values and the "Depth Surface" mode configuration is selected to display the "Roughness" data.

Note: the isobathes are drawn in black to distinguish them in "Depth surface" mode.

Only one type of representation ( "Isobathe" display mode, "Depth surface" display mode) is applied to only one type of data value chosen between the depth,E1, E2 or seabed class data.

Creating Route From 2D Contour Line

Your MaxSea version has the 2D module, you can easily create a route by follow-up a selected 2D contour line on the chart.

1.Display 2D view in selected Isobathe Mode in your navigation zone area (See related topic to learn more on 2D Display Configuration)

2.Use the Right-click menu on a drawing 2D contour line to select it

3.Choose and click on "Create Route From Contour".

4.The route will be created along the 2D Contour Line with limits defined inside the zone area display as shown in Fig.1. The Waypoint Route number depends on the scale chosen during action.

(1)- View of selected zone area before creating route

(2)- left-hand corner where the waypoint route is created in the selected zone area limit display

(3)- right-hand corner where the waypoint route is created in the selected zone area limit display

(4)- routes created from following contour lines

All new routes are automatically added in the Routes Center and appear with each name beginning by " "CTR xxx" (xxx is a serial number of new creating route)

How to Import Data To MaxSea 3D Database

Hardware configuration

Hard disk

As the database is to be stored on the hard disk, we strongly recommend you to choose a fast hard disk (ATA-100 or better if possible ) with a large capacity (20 gigabytes or more) formatted on a single FAT 32 partition.

Video card

In order to obtain the best 3D display results, you should choose a video card with 3D capabilities and a minimum of 16MB of video memory.

The best performance will be reached if you have the possibility to display the 2D and 3D windows on two different screens. To do that, you will have to equip each screen with a 16 Mb video card (or a dual video card).

Memory

Under Windows 98 SE we recommend a minimum of 128 Mo of SRAM memory (PC100).

Under Windows 2000 PRO or XP, we recommend a minimum of 256 Mo of SRAM memory (PC100).

Operating system

3D Database Import

Import data to MaxSea 3D database

You can import your own data using the files you have previously recorded or and also miscelously data .

You can also import data

From a version 8.1 DataBase (Be careful and don’t use this option if the version 8.1 database contains DEM grid data)

From vector chart Data

From files

1.From User Data

2.From ASCII file

3.From D.E.M. ("Mapmedia" 3D charts and MaxSea "3D charts world database")

To import data, select [Import to 3D data base] from the [File] menu

Then select the type of data you wish to import:

243

MaxSea Operator Manual version 12.6

By choosing in the first zone area to import your previous database:

1.Check corresponding box it is a MaxSea database previous version (between User Data or Vector Chart Data).

2.Search and select previous Database.

3.To import Vector charts database

4.To import data from User data (file PTF file, PBG on), ASCII (xyz file), D.E.M. (Digital Elevation Model, *.GRD, *.G03)

5.The path zone file import data

6.Use "Add data files" button to select a new data file

7.Use "Clear selection" button to clear a data file from the list before importing

Note : if the import takes too much time, you can cancel by clicking on the "Cancel" button.

7.Use "Clear selection" button to clear a data file from the list before importing

Note : if the import takes too much time, you can cancel by clicking on the "Cancel" button.

Import data from a previous Database

There are two ways to import data from an 8.1 Database

1 - The most secure way to import the 3D data from version 8 is to follow these steps:

245

MaxSea Operator Manual version 12.6

Import depth value upon the fishing area from the grid files:

•Check D.E.M. box (Digital Elevation Model)

•Click Add files to select 3D data files

•An "Open file" dialog box appears that allows you to select the file you wish to import. Import depth value upon the fishing area from the Cmap93Ed2 CDs, :

•Select [Open chart…] from [File] menu (the CMAP chart must be open before the import)

•Check the "C-Map" box to select the chart from the CD.

Import the "User data" in the 3D database version 8:

•Check the "User Data" box

•Click on the "Choose database folder" button to import old user data from an exiting database.

2 - An option available to automatically import his Vector Charts depth data from the version 8 3D database.

IMPORTANT

Be careful when using this feature.

This method can be used ONLY if the user has not imported DEM data (in such a case the accuracy could be significantly decreased).

All data is imported with the old parameters (you can't, for example, modify Tide parameters).

Only version 8 User Data from fishing plan or from a PBG tracking file can be exported and included in the 3D database.

Import "User data"

To import depth information from User data :

Check "User data (*.ptf)",

Click the "Add files" button and the Windows Open file dialog will appear.

Search and select a "PTF" file you wish to open.

246

3D Bathymetric database

Click on "Open" and the file path will appear as it is shown in the following window.

Click on Add Files again to add simultaneously several User data files.

If you want to delete a selected file, click the file to select it and click the Clear Selection button to delete It. Click "OK" to validate and start the import User Data process.

Before importing data into the 3D database, you may adjust several parameters.

For more details see related topic: How to configure 3D data Import

Note: all data with null depth value will not be imported.

Inserting lines and points

If you wish, you can plot your own bathymetric data on an existing point or line and then import it into your 3D database:

247

MaxSea Operator Manual version 12.6

Create or display the point or line,

Double click on the point with the Select tool to display its Properties dialog box.

Enter in a depth value in the corresponding text area

Validate by clicking OK.

Note: if you want to modify all the depth value for a line, click on the "All the line" button.

You can add this new information to your database by importing the ptf file. (You must save the pft file before importing data from it.) For more information see Import "User data").

Before importing "ASCII (*.xyz)" files

The MaxSea data format:

1.Latitude and Longitude are in decimal degree.

2.The depth is in meters,

3.By default the scale of import is 1/10000.

The standard lines of this basic format will be: X Y Z.

Each data field must be separated by a space.

Note: you can change import data parameters, to do this you have to add information in the ASCII file header.
