Overlay area
You can choose whether the aerial overlay is shown for land areas
only, or for land and sea areas.
• On land shows a normal chart view for sea areas and overlays
aerial photography on areas of land. This can help interpret your
surroundings while keeping important navigational data visible.
• On land and sea shows aerial photography of both land and
sea areas. This can help in distinguishing between deep and
shallow water (dark blue and light blue, respectively), and to
view land features simultaneously.
The overlay area can be set up using the Aerial Photo Overlay func-
tions of the Cartographic Setup Menu.
