The Main View

The Main View contains the map and sonar views, along with controls to adjust the sonar view and play-back:



(1) Header

The header is displayed on top of the data panel when the mouse pointer is moved towards the top of the sonar viewer window. When the mouse pointer is moved away from the top of window, the header is removed from view.



1. Back to Load File View

Return to the Load File view, from where recent files or folders can be selected.


2. Mouse mode panel

Buttons within the mouse mode panel can be used to select the current mouse mode, which applies to both the map and sonar views. Available modes are; select, zoom, pan (move), drop waypoint and measure.


See Mouse Control.


3. Current loaded sonar file

The name of the currently loaded sonar file, including the full file path.


4. Window controls

Standard window controls for minimising, maximising and closing the application window.


(2) Data Panel

The Data Panel shows information for the current position in the sonar file. This information includes position, heading, course, speed and depth and is displayed in the units specified in the Load File View.

Note that the current position within the sonar viewer is defined as the most recently visible sonar return, For 2D displays this is the right edge of the sonar display and the top of the side-scan display.


(3) Map View

The Map View displays the sonar track over a base map that can be moved and zoomed. If the loaded sonar file contains side-scan, then the side-scan sonar is shown along the course of the track. Otherwise, track-points are shown that are colour coded according to depth.


See The Map View.


(4) Sonar View

The sonar view is a multi-channel sonar viewer with a separate window for each available sonar channel. Sonar can be replayed at speeds of up to 30x, panned and zoomed.


See The Sonar Viewer.


(5) Control Bar

The control bar contains functions to toggle the display of the map and sonar views and individual sonar channels, along with playback and position controls for the sonar viewer:



1, 2. Toggle Map View and Sonar Viewer displays

The sonar viewer can be arranged as a split window, with the map view alongside the sonar viewer, or the entire window can be dedicated to either the map view or the sonar viewer:


Sonar viewer only


Map view only


3. Image snapshot

Use the image snapshot function to record an image of the current sonar viewer display. Images can be copied to the clipboard, so that they can be pasted directly into other applications, or saved to file in PNG or JPG formats.



The data panel (shown at the top of the sonar viewer) can be hidden by de-selecting the Include data panel option, and waypoints can be hidden by de-selecting Include waypoints.


4. Current sonar log time

The position in the sonar log, expressed as time. Note that position is determined by the leading edge of the sonar channel displays, so time is never shown as zero.


5. Sonar playback controls

Stop or start sonar playback. Position of the sonar can be modified during sonar playback through use of the sonar position scroll-bar or by panning with the mouse within individual sonar channel displays.


6. Sonar playback speed

Sonar can be replayed at speeds of up to 30x. Note that adjusting the playback speed will automatically start sonar playback.


7. Sonar position slider

The sonar position slider is used to adjust the current sonar position.


Grab and drag the slider thumb using the left mouse button to move forwards or backwards by any amount.

Click in the areas to the left or right of the thumb to move backwards or forwards once screen at a time.

Click in the arrows at either end of the slider to move backwards or forwards by a small amount.


Sonar position can also be adjusted by clicking and dragging within the individual sonar channel displays, with the mouse in move mode (see The Sonar Viewer).
