1.3 The Chartplotter Display
The PLUS seriesdisplaycan includes a Chartplotter. The chartplotter
includesa small-scale world map and detailed navigation information is
displayedwhen a cartographic chart card is installed. The details displayed
dependon the chartzoom level selected. A plottermodeis provided to enable
routeplottingand trackingat large scales even when a chart card is not
installed,or when the chart is zoomed beyond the availablecartographic
detail.A typicalchartplotter screenis shown in Figure 1-5.
The chartplotteruses positioninformation from a GPS, DGPS,WAAS or
Loran-Cinstrument. Once the position fix has been established,your vessel’s
position,if on screen,is shown as a boat shape pointing in the direction of the
current heading(or COG if heading data is not available).If no heading or
COG data is available, the vessel is shown as a circle.
The chartplotterscreen includes a statusbar that displays chart scale, with
either cursor position, range and bearingor,when the cursor is homed to the
vessel(by pressing FIND SHIP), vessel position, Speed Over Ground (SOG),
Course Over Ground (COG) and fix type (VES POS, DIF FIX or SD FIX).
The statusbar alsoindicates if radar/chartoverlayis switched on.
Any waypoints you have placedare displayed (unless you turned them offin
Chart Set Up as described in Chapter 7) and the current route is shown.
Information can be viewed on-screen by positioning thecursor over a
waypoint, current route or chart object.The chartplotterscreen can also show
additional information, depending on your currentlyselectedoptions, set up
selections and data availablefrom other equipment.
An example chartdisplay, in its default configuration,with a chart card
installed,is shown in the following illustration.
Several functionsare available to controlthe display as follows:
• Zoom in/out and Pan the Display
• Offset the Chart or Center the Chart around the Vessel
• Synchronize the Chart and Radar (if radar data is available)
