BHD - 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 longitudinal profile shape and a cross profile shape through the CoG of the vessel is required. These shapes are defined in the Database Setup program when creating object shapes. An Aft view may also be useful.

The following directions assume a Profile Display has already been created. Refer to BHD - 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 are discussed here. For more detailed information refer to the Online Help.

Profiles
Objects	Terrain	Measurements	Lines	Sounding Grid
View
Setup	Scale	Grid
Settings
Orientation - heading reference		Origin - view perspective (Stb., Port, Front, Aft)

The initial view should look something like this:

Notes:

The dredger is initially positioned centered around the CoG (Reference Point) of the first object defined in the template database, in this case it is the CoG of the Boom. Centering is performed in both the horizontal and vertical directions. You can change the focus to the CoG of another object such as the pontoon or bucket.
The first layer in the sounding grid is automatically loaded on creating the display; in this case the upper blue line with hatching below.
The Design layer is also loaded automatically. This is the horizontal line below the active sounding grid layer.
The black arrows at lower and right edges are pointers to the CoG of each defined object.

The display can be customized as follows:

View Properties - Profiles

Objects

From the Select pull down menu, choose Vessel.

The View Properties dialog opens. Click on the Objects button .

Selecting any other option in the Select pull down menu also opens the View Properties dialog with the focus on a different page.
Selecting View Properties from the View menu opens the same dialog.

All the Objects defined in the template database are listed.

Choose a reference Object, and the node on that object, on which to center the main window. Coordinates come from the computation selected.
Make selections and parameter value entries to set Object Properties. These can be set for any Object that is currently highlighted.

Terrain

Click on the Terrain button

which changes the parameters in the right pane.

By default the first defined layer in the active sounding grid is loaded as a terrain.

So too is the Design model if it has been defined as a layer and filled with model data.

Use the

button to load additional terrains. For each terrain select the source file and layer.

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.
If a sounding grid was selected in the 'Controller's Session Setup - Storage', the first defined layer will automatically be shown here, named Sounding Grid <Storage>.
When under-dredge and/or over-dredge is used, this is also shown.
If necessary remove the sounding grid chosen in the Session Setup here by using the

button.

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.
When selecting a Multibeam system, the swath must be set.
Using direction starboard or port, the readings will show as a measured terrain when drawn as lines.

Safety Line - It is possible to add a nominal safety line. A line is displayed at the manually entered depth (in survey units).
This line can be used in case no design is available and a depth needs to be displayed.

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.

Highlight the selected Type and select the properties for each layer separately.

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 Safety 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	This option is only available when the layer type Sounding Grid is selected. Depths in the Profile Display are 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 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.

Click on the Measurements button

.

Click on

to create a measurement.

Select Object, Node, Computation and Terrain (as defined under the Terrain button) upon which the computed measurement is based.

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.

Make parameter value entries and parameter selections to define properties for each measurement individually.

Measurement
Line Color	Select the Color to use for the measurement line drawn from node to a layer in the terrain, or to water level.
Label
Show	When you choose to Show the labels the next menu items appear:

Setup

Click on the 'View' button and then on the Setup button

.

Select parameters to determine object tracking.

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 in the toolbar can be used at all times while on-line. 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.
Show connected lines	The data points from the echosounder are Connected with a line.
Legend
Style	By default the Legend is drawn outside the grid.
Legend	Select a color for the Legend. (Only available when drawn outside the grid.)

Scales

Click on the Scales

button to set the scales of the Profile Display in horizontal and vertical direction.

Make parameter selections and enter parameter values.

Scaled display	When enabled this option scales the object according to the scales of both the vertical and the horizontal legends. The aspect ratio of the object is not maintained. When disabled this gives some manually adjustable settings in the Vertical and Horizontal lines listed below.
Scale objects	When Scaled Display is disabled this option can be used to scale objects on one axis or both axes: Both Axes - The object is sized according to the scales of both the vertical and the horizontal legends. Horizontal Axis - The object is sized according to the scale of the horizontal legend. (Maintains the aspect ratio of the object). Vertical Axis - The object is sized according to the scale of the vertical legend. (Maintains the aspect ratio of the object).
Vertical
Zoomlock vertical range	Lock the vertical range so it will not change when zooming in or out.
Maximum height	This is the height value at the top of the display.
Minimum height	This is the height value at the bottom of the display.
Horizontal
Use line as reference	Used to show the object relative to a line. KP values are shown on the horizontal axis instead of distances in survey units.
Line	When Use Line As Reference is activated, choose an existing line from the drop down menu. Different mainlines can be selected, but need to have been activated in the Controller - Settings - Session Setup - Planning first. These Additional Mainlines were defined in the program Line Data Manager or in the online Navigation Screen with the button named Waypoint Planning.
Zoomlock horizontal range	Lock the horizontal range so it will not change when zooming in or out.
Left	The range value shown to the left of the center of the display.
