CodeVerticalReferenceType
urn:aero:airm:1.0.0:LogicalModel:Subjects:Common:Codelists:CodeVerticalReferenceType
A code indicating the reference for a vertical distance. Two series of values exist: 1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid; 2) distance based on a difference of pressures, according to the standard atmosphere.

Properties:
| Properties | Definition | Type |
|---|---|---|
| MSL | The average location of the interface between the ocean and the atmosphere, over a period of time sufficiently long so that all random and periodic variations of short duration average to zero. |
enum value |
| WGS84 | WGS84 is an Earth-centered, Earth-fixed terrestrial reference system and geodetic datum adopted as the common geodetic reference frame for civil aviation. |
enum value |
| STD | The vertical distance is measured with an altimeter set to the standard atmosphere. |
enum value |
| SFC | The distance measured from the surface of the Earth (equivalent to AGL - Above Ground Level). |
