Provides access to members that control the properties of a vertical coordinate system.
A vertical coordinate system has two types. It can either be gravity-related, which requires a VerticalDatum; or ellipsoid/spheroid-based which requires a horizontal Datum. A horizontal Datum is the same as one used for a geographic coordinate system. You will also need a (linear) projectedUnit object. A VCS has two parameters. The positiveDirection value defines whether the vertical coordinate system has positive values 'up', heights, or 'down', depths. Use -1 for positive depths. The verticalShift parameter is a way to identify this VCS as offset from some other known surface. For example, you might know that a dataset's depths are referenced to mean lower low water (a tidal level). You might also know that for this dataset, mean lower low water is 1.23 meters below local mean sea level. The VCS could be defined for mean sea level but with a verticalShift of -1.23.
