gml:VerticalCRSType

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 an inseparable part of a 3D coordinate tuple defined in a geographic 3D coordinate reference system. 

Complex type information

Content

• Sequence [1..1]
  from type gml:AbstractReferenceSystemBaseType
  gml:metaDataProperty [0..*]    Contains or refers to a metadata package that contains metadata properties.
  gml:srsName [1..1]    The name by which this reference system is identified.
  from type gml:AbstractReferenceSystemType
  gml:srsID [0..*]    Set of alterative identifications of this reference system. The first srsID, if any, is normally the primary identification code, and any others are aliases.

  gml:validArea [0..1]    Area or region in which this CRS object is valid.
  gml:scope [0..1]    Description of domain of usage, or limitations of usage, for which this CRS object is valid.
  1. gml:usesVerticalCS [1..1]    Association to the vertical coordinate system used by this CRS.
  2. gml:usesVerticalDatum [1..1]    Association to the vertical datum used by this CRS.
