org.geotools.referencing.crs.DefaultVerticalCRS

A 1D coordinate reference system used for recording heights or depths. Vertical CRSs make use of the direction of gravity to define the concept of height or depth, but the relationship with gravity may not be straightforward.

By implication, ellipsoidal heights (h) cannot be captured in a vertical coordinate reference system. Ellipsoidal heights cannot exist independently, but only as inseparable part of a 3D coordinate tuple defined in a geographic 3D coordinate reference system. However GeoAPI does not enforce this rule. This class defines a {@link #ELLIPSOIDAL_HEIGHT} constant inviolation with ISO 19111; this is considered okay if this constant is used merely as a step toward the construction of a 3D CRS (for example in a transient state during WKT parsing), or for passing arguments in methods enforcing type-safety.
