Chapter 5: 3D Chart
5.1 Important
3D Chart functionality
To obtain the best results from the 3D cartography application you should make sure
that your display is receiving accurate heading and position data from a suitable
source and that you are using a chart card incorporating 3D cartography for the
appropriate area.
Safety
The 3D chart is an aid to visualization. When navigating with your 3D chart you
should also check your 2D chart and ensure that a route is safe. Until you are
familiar with interpreting the 3D chart, you should take every opportunity to
compare the displayed objects with visual targets, such as buoys and coastal
structures. You should practice harbour and coastal navigation during daylight and
in clear weather conditions. The simulator mode can also be used to help you gain
experience.
It is strongly recommended that before you use your 3D chart application, you read
and understand
Chapter 3:Working with Waypoints
and
Chapter 4:Using the Chart
.
CAUTION:
The 3D application should not be used as a substitute for good navigational
practice nor for official government paper charts. Do not use this application
before you have read this chapter.
5.2 An introduction
This chapter describes how to use your 3D chart and its various functions including:
• Setting up your 3D chart (see
page 128
).
• Using the controls (see
page 117
).
• Setting the operation mode (see
page 119
).
• Changing the view point (see
page 120
).
• Rotating the selected view (see).
• Changing the pitch (see
page 118
).
• Exaggerating the view (see
page 122
).
• Sychronizing the 3D and 2D chart (see
page 125
).
• If a transducer is fitted - displaying the fishfinder cone area (see
page 126
).
