3.3.2 Overlay Status Icons
Icons indicate which overlays are present at the current map range. A crossed out
icon means the overlay is active, but data is unavailable due to a failure, test, or
standby condition (where relevant).
The absence of an overlay icon means one of two possible conditions:
1. Overlay not present at the current detail level or zoom setting.
2. Overlay control is off.
