6.1.1.

A set of symbols is provided within Debrief. The symbols can either be attached to a text label, or used to highlight a current vessel location when stepping through tracks.

Twenty-two Symbols are provided in 3 sizes. When the 2 smaller sizes are shown, any internal characters (as used in the sonar buoys) are not plotted.

6.1.2. Use in buoy patterns

Symbols are assigned to buoys in a buoy pattern at the Pattern Builder stage. After selecting the type of pattern to be created the user is able to select which type of symbol is used for the buoys (at this stage only the buoy-related symbols are provided). For patterns which include a kingpin (Field, Barrier, Wedge), a kingpin symbol is plotted for the first buoy.

6.1.3. Use in labels

Any label placed on the plot has a symbol type property (although the symbol itself may not be visible). The symbol can be changed through the properties window, or by right-clicking on the label on the plot.

6.1.4. Use in tracks

The final area where symbols are used is when stepping through tracks. Each vessel track has a symbol type property which is shown when the plot has SymbolHighlighter selected as the current highlighter.

To access this property, select the Properties button on the Tote (first button on bottom row), and change the current highlighter to "SymbolHighlighter". Now the current data point on each track will be shown using the symbol for that track.

By switching to Snail mode and reducing the reducing the Trail Length to zero, a GOP-type plot can be shown.
