Sometimes it is easier to see certain topographical features if they
are exaggerated. Adjusting the exaggeration has the effect of
vertically stretching objects on the chart, making it easier to see
their shape and position. This could be particularly helpful if you
are shing, for example.
Adjusting the 3D chart exaggeration
In the 3D chart application:
1. Press the PRESENTATION softkey.
2. Press the 3D VIEW OPTIONS softkey.
3. Press the ADJUST EXAGGERATION softkey.
4. Using the trackpad, select the required amount of exaggeration.
5. Press the OK button.
3D chart decluttering
You can declutter the 3D chart to reduce the amount of objects
and detail shown.
Navigating in an area that shows a lot of information on the chart,
such as navigation marks, can be confusing. Depending on your
chart view level it can make features or even your position difcult
to see. Declutter helps you to reduce this confusion and make the
chart clearer, by removing some objects from view.
Decluttering the 3D chart
In the 3D chart application:
1. Press the PRESENTATION softkey.
2. Press the DECLUTTER softkey until the ON or OFF option is
selected, as appropriate.
3. Press the OK button.
Aerial photo overlay on 3D chart
You can overlay an aerial photograph on the 3D chart display to
help you interpret your surroundings.
Aerial photos cover the navigable waters up to 3 miles inside the
coastline. Beyond these limits the land will appear green (color
charts) and grey (black and white charts). The level of resolution
and the availability of a colored overlay is dependent on the region
covered by the chart card.
The following images show the difference between the standard 3D
chart display, and the 3D chart display with aerial photo overlay:
