TSHD - Profile Display
Profile Display
The Profile Display provides a slice view of the dredger and the sounding grid displayed from four different angles (starboard, port, aft and front).
IMPORTANT: In order to display objects in the profile display a long profile or a cross profile through the CoG of the vessel is required. These are defined in the Database Setup program when creating object shapes.
The following directions assume a Profile Display has already been created. Refer to TSHD - Online Displays for details about creating a display set and adding new displays.
Take the following steps to configure the Profile Display; only a few important settings will be discussed here. For more detailed information refer to the Online Help.

Orientation - heading reference | Origin - view perspective (Stb., Port, Front, Aft) |
The initial view might look something like this:
Notes:
- The dredger's position is offset because the display is centered on the CoG defined for the object. In this case it is located toward the stern in proximity to the upper suction pipe. You can change the focus to the CoG of another object such as the dredger CoG or the drag head.
- The first layer in the sounding grid is automatically loaded on first creating the display; in this case the blue line with blue hatching below.
- The Design layer is also loaded automatically. This is the orange line with orange hatching below it.
- The arrows at lower and right edges are pointers to the CoG of each defined object.
The display can be customized as follows:

These are the Terrains available for selection:
Layers | |
---|---|
Type | Sounding Grid - Select the sounding grid to use from the standard Windows browse dialog. Then select the correct layer in the next column. Echosounder - Single observations from echosounders can be displayed in real-time. This enables you to analyze the depth readings in comparison to a previously created terrain. Safety Line - It is possible to add a nominal safety line. A line is displayed at the manually entered depth (in survey units). QPD Processing - Select *.qpd processed files. Multiple files can be selected. QINSy Mapping - Select a *.pro file. (This is the old format. It can still be used, but will be phased out. Use the *.qgf format instead.) It is only possible to select one file at a time, but you can add more. QGF Design Model - Select a *.qgf file. (This is the new format.) Sounding Grid <Storage> - If a sounding grid was selected in the 'Controller's Session Setup - Storage' it will automatically be shown here. Water Level - Mean Actual Water Level, i.e. water surface, is shown. Additional Terrain <Session> - A terrain from the Controller's Session Setup menu 'Additional Terrains' can be selected here. |
The terrains are displayed in the order in which they are added; the bottom one in the list is displayed on top of earlier entries.
Terrain | |
Line width | Enter a width in pixels. |
Color | Select a color. |
Fill type | Choose a type: Solid fill - Area below selected layer Type will be filled completely with the selected color. No fill - Only a line will be shown to indicate the terrain. Hatch fill - Area below selected layer Type will be filled with hatch lines in the selected color. Color banding - Only available for Sounding Grids. Depths in the Profile Display will be shown in their own color ranges, similar to depths in a sounding grid shown in the Navigation Display. ![]() |
Hatch selection | This option is only available when the fill type was set to Hatch fill. |
Safetyline | Not available for layer type Sounding Grid. |
Show additional safety line | For each selected layer an additional safety line can be added. (Except for Sounding Grid.) Largely unrelated to dredging, this is mainly used during a bundle tow, to indicate a safe depth for the bundle. |
Offset value | Enter the offset value in meters and the additional line will be shown offset from the selected layer. A positive offset gives a line above the selected terrain. A negative value gives a line below the selected terrain. |
Color Banding | Only when the layer type Sounding Grid was selected will this option be available. Depths in the Profile Display will be shown in their own color ranges, similar to depths in a sounding grid shown in the Navigation Display. |
Active layer | Select a layer. |
Active attribute | Select which values to show. |
Reference layer | Select a layer, if needed. |
Reference attribute | Select which values to show. |
Mode | Set which results to show: a difference layer or a cumulative layer. |
Echosounder | Only when the layer types Echosounder or QPD Processing were selected will this option be available. |
Show starboard & port view | Show starboard and port view of recorded data. When switched off, no data is shown. Only available when layer type was set to Echosounder. |
Use nadir beam | Use the beam in the middle of the array to show depths from when using a multibeam echosounder. Only available when layer type was set to Echosounder. |
Time span | Define how much echosounder data should be shown in the Profile Display (in seconds). |

Measurements
Measurements are calculated from a node to a profile; they are not raw measurements.
If a mapping file is selected as terrain under the Terrain menu, the active layer is set there. Only that layer is displayed here.
If a different layer is required, set it under Terrain again.
A mapping file will slow down display performance.
Measurement | |
Line Color | Select the color to use for the measurement line drawn from node to terrain. |
Label | |
Show | When you choose to show the labels the next menu items appear : |
Fill label background | The label is filled and the text becomes white. |
Offset right / left | When no Offsets are entered, the label is drawn halfway down the measurement line (in vertical and horizontal direction). To change the label location use an offset: -ve moves the label left, +ve moves it right. |
Offset up / down | To change the label location use an offset: -ve moves the label down, +ve moves it up. |
Font | The font of the label (font, font style, size and color) can be changed using the browse button ![]() |
Trend | |
Show trend | This option shows the trend of a measurement and is typically used during a bundle tow. It show the speed of movement (in survey units) for the bundle. When switched on the following menu items appear : |
Minimum value | If enabled, define a minimum value (in height units per second) under which a (positive or negative) trend value is not shown. This setting can be used to hide zero or insignificant trend values. |
Maximum age | If enabled, define the maximum time (in seconds) that a trend value remains visible if it is not updated for some time. This setting is only useful if position data is received at irregular intervals. |
Font up | Define the font (font, font style, size and color) of the speed value when the bundle is moving up. |
Font down | Define the font of the speed value when the bundle is moving down. |
Location | The location of the trend label can be selected. For example it can be placed to left or right of the node. |

Setup
General | |
Relative motion | When Relative motion is on, the object remains in the center of the display; only the terrain is moved. When Relative motion is off, the terrain is stationary and the vessel moves across the display and may disappear. |
Object tracking | Option only available when Relative motion has been activated. However the Object Tracking button ![]() When Object Tracking is on, the object sails to the edge of the display and is then placed back in the middle of it. When Object Tracking is off, the terrain is stationary and the vessel moves across the display. But, since Relative Motion is switched on to access this setting, the vessel will remain in the middle of the display. When the vessel has sailed outside the display and you can not find it with the zoom functions, turn Object Tracking on to retrieve it. |
Orientation | The object can be viewed relative to a line heading or to the heading of any of the calculated objects/nodes. |
Origin | Select which view of the object is displayed in the main panel. The view is projected onto the line if Orientation was set relative to a line heading. |
Show big dots | The nodes are shown as big dots for easier identification. |
