Aerial photo overlay
The aerial photo overlay feature 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) or 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.
Aerial photo overlay is accessed via the PRESENTATION and CHART LAYERS soft keys
and can be applied to individual chart windows.
