Provides information about the vertical coordinate system (VCS) component of a SpatialReference object.
Spatial references are comprised of a coordinate system and storage and processing parameters (tolerances and resolution settings). A VCS may also be included, containing information about the Z (or vertical) coordinates. For example, a point has a Z value of 100.0, but without knowing it's VCS information we are left with the following questions:
- 100.0 from what? What is at 0.0?
- 100.0 in what units? Meters, feet, miles?
- 100.0 in which direction from 0.0?
The name of the vertical coordinate system's datum.
The positive direction of the z coordinates; 1 is upwards, -1 is downwards (in the direction of gravity).
The factory code of the vertical coordinate system.
The name of the linear units.
The name of the vertical coordinate system.
The vertical shift of the vertical coordinate system.
