def vertical_datum
  @vertical_datum
end

#vertical_unit ⇒ Object (readonly)

Gets the units used along the vertical axis. The vertical units must be the same as the CS_CoordinateSystem units.

Class Method Details

.create(name, vertical_datum, vertical_unit, axis, *optional) ⇒ Object

Create a VerticalCoordinateSystem given a name, a VerticalDatum, a LinearUnit, and an AxisInfo. The AxisInfo is optional and may be nil. You may also provide the optional parameters specified by the Info interface.
