Overlay Status Icons
Icons indicate which overlays are present at the current map range.
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.
Data Not Available
This icon means the overlay is active,
but data is unavailable due to a
failure, test, or standby condition
(where relevant).
