Displaying an aerial photo overlay
If you are using a suitable chart card, the aerial photo overlay feature can be applied to
individual chart windows and will help you to interpret your environment and its
features. They 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.
Note:
If an aerial photo overlay is applied to a chart window that is set to system view,
the overlay will be displayed in all other system view chart windows.
To display an aerial photo overlay:
Adjusting the level of opaqueness
You can adjust the balance between the chart and the aerial photograph by changing
the overlay’s level of opaqueness. Any changes that you make will affect all displays in
your system.
