5.10 Aerial photo overlay

You can overlay an aerial photo onto the 3D image. This will help you to interpret your
environment and its features. 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.
Standard 3D image
Aerial photo overlay is controlled via the 3D Chart Setup Menu. See
details.

5.11 Making the view clearer

You can make the view clearer using the following features:

• Exaggeration.

• Declutter.
Exaggeration
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 fishing, for example.
