Chapter 5: The Chart Application
If you have a Raymarine GPS attached, it will automatically update
when you adjust the datum. If you use a third-party GPS, you need
to update its datum separately.
CAUTION: Changing the chart datum does not cause any
waypoints or routes stored in the chartplotter to move on
the display, although their latitude and longitude changes
to reflect the new datum. When you add waypoints to the
waypoint list, make sure they are referenced to the same
datum.
Chart offset and cartography setup
This feature allows you to move the position of the chart to correct
positional errors in the cartography. The adjustment is indicated as
a distance north/west (+ve) or south/east (-ve) from your vessel to
a maximum of 1000m. An indicator in the chart window tells you
when chart offset is enabled.
Restore chart offset to zero when you begin using a chart with the
correct georeference.
Please report chart errors to Navionics (see
page 210
).
