Altitude/Depth
An amplifier that displays either altitude, flight level, depth for submerged objects or height of equipment or structures on the ground, the minimum, maximum and/or specific altitude (in feet or meters in relation to a reference datum) or depth (for submerged objects in feet below sea level). See 5.3.7.6 for content.
Format:
Symbol Set: All but 40 & 60
Remarks:
SM = Statute Miles
DM = Data Miles
Notes:
The Renderer handles the whole value as a string for Single Point Icons.
For multipoints, it expects just a number and an accompanying attribute {@link MilStdAttributes.AltitudeUnits}
Default behavior assumes feet.
