2.1 Chart Type
A world map in raster chart format is included in your unit. A vector chart for the US
coastline (Alaska and Hawaii included) is provided also. To use this chart plotter as a
navigational aid, have electronic charts (stored in the internal memory) for the area
you navigate. Contact your dealer about charts for your area.
There are five types of chart format in this equipment: [Raster], [S-57], [C-MAP], [Navi-
onics] or [Fishing].
[Raster]: Raster charts are digitized scans of NOAA paper charts. Raster charts have
information like notes, source diagrams, tidal diamonds, horizontal and vertical datum,
etc.
[S-57]: S-57 formats are vector charts (digital files) that contain marine features and
information created for marine navigation. These charts are made according to the In-
ternational Hydrographic Organization (IHO).
[C-MAP]: Vector chart (data by C-MAP)
[Navionics]: Vector chart (data by Navionics)
[Fishing]: Fishing charts are vector charts that show only detailed depth contours.
These are available for US waters.
How to select a chart type
1. Select the plotter display on the display selection window (see section 1.5).
2. Select [Chart] from the RotoKey menu.
3. Select the chart type from [Raster], [S-57], [C-MAP], [Navionics], [Fishing] or [Au-
to]*.
*: [Auto] automatically switches the chart type according to availability and chart prior-
ity setting (priority setting: [Plotter Display] - [Chart Priority in Auto Mode] - [Vector] or
[Raster]).
