| * A 1-dimensional coordinate system for heights or depths of points. |
| * OGC/ISO do not provide an exact definition, since the complexity of vertical CS fall outside the scope of ISO 19111. |
| * Some examples of vertical coordinate systems are: |
| * |
| * <ul> |
| * <li>Height in metres from a surface dependent on the Earth's gravity field</li> |
| * <li>Height or depth represented by an atmospheric or water pressure measurement.</li> |
| * <li>Depth represented by the time needed for an echo signal to travel.</li> |
| * <li>"Sigma-level depth" (used in oceanography) as a dimensionless quantity.</li> |
| * </ul> |
| * |
| * The above examples show the variety of units of measurement which can be associated to vertical positions. |
