Introduction

Multibeam data are imported by the command Import Multibeam Sonar Data. As a part of the import the make and vendor of the multibeam echosounder is registered. Vital information like the mount parametres are read from the datafiles and will be saved in a Vessel configuration file in the project. Multibeam files with different installation parameters will have reference to different vessel configuration setup.

The Vessel Configuration Manager is where the parameters for the multibeam survey lines can be verified. It is also possible to change the values from the survey to improve the processing result.

 

How to open the Vessel Configuration Manager

The Vessel Configuration Manager is opened from the Seafloor Main Menu. Click Edit and then click Vessel Configuration Manager.

 

It is also possible to open the Multibeam folder tools on the right click menu. From the menu select the Vessel Configuration Manager entry.


The Multibeam folder menu.


The content of the menu

The Vessel Configuration Manager dialog.

 

The Vessel Configuration Manager dialog is shown in the image above. The dialog is divided into the three parts:

  • Project
  • Vessel configurations
  • Survey lines

Each part will be discussed further in this section.

The Vessel Configuration Manager dialog is of type modal, which means that other functionality in Geocap is inactive until the dialog is closed by the OK or Cancel buttons.

 

The Project part

The pulldown menu after the text Project contains a list of open projects in Geocap. Normally only one project is open, but in Geocap it is possible to have several projects open at the same time. Each project can have one or more vessel configurations. The selection of project decides which vessel configurations which will be shown in the vessel configurations part. 

The Vessel configurations part


The right-click dialog in the Vessel configurations part.

The Vessel configurations part shows the configurations for the actual project. If the project contains data from one multibram echosounder only, normally one configuration is necessary.
When clicking the name of a vessel configuration the corresponding Survey lines are shown below.
During the import of multibeam survey data, the configuration parameters from the echosounder is checked against existing vessel configurations. All parameters are checked, like the type of echo sounder, number of transmitters and receivers (single head, dual head), the mounting parameters for the echosounder and the motion sensor (offsets and rotations), content of datagrams (depth, range), etc. If any setting is different a new vessel configuration is created. This means that the operator can check the configurations to see if there are any changes during a survey.

 

The Survey lines part

See the path to the survey line.


When clicking the name of a vessel configuration above the corresponding survey lines are shown in the list.
By holding the cursor over a survey line name a dialog shows in which folder the survey line is located in the project.
