VerticalType

Vertical coordinates are measured relative from the ellipsoid surface.

Vertical coordinates are gravity-related (e.g. measured relative from the geoid surface).

Coordinates of this type can usually be interpreted as pressure altitude resp. height above mean sea level.

Vertical coordinates are measured relative from the terrain surface.

Coordinates of this type can be interpreted as radio altitude.

Using this type requires heightmap accesses, which may cause blocking I/O work.

Vertical coordinates are measured relative from the terrain surface mesh, in its current state of tessellation.

Coordinates of this type can be interpreted as radio altitude.

When the terrain surface mesh has not been specified, vertical coordinates of this type will revert to Height, which may cause blocking I/O work. If the terrain surface mesh is not ready (see IMesh.IsReady), vertical coordinate offsets will be zero.
