gml:ConcatenatedOperationType

An ordered sequence of two or more single coordinate operations. The sequence of operations is constrained by the requirement that the source coordinate reference system of step (n+1) must be the same as the target coordinate reference system of step (n). The source coordinate reference system of the first step and the target coordinate reference system of the last step are the source and target coordinate reference system associated with the concatenated operation. Instead of a forward operation, an inverse operation may be used for one or more of the operation steps mentioned above, if the inverse operation is uniquely defined by the forward operation.

Complex type information

Content

• Sequence [1..1]
  from type gml:AbstractCoordinateOperationBaseType
  gml:metaDataProperty [0..*]    Contains or refers to a metadata package that contains metadata properties.
  gml:coordinateOperationName [1..1]    The name by which this coordinate operation is identified.
  from type gml:AbstractCoordinateOperationType
  gml:coordinateOperationID [0..*]    Set of alternative identifications of this coordinate operation. The first coordinateOperationID, if any, is normally the primary identification code, and any others are aliases.
  gml:remarks [0..1]    Comments on or information about this coordinate operation, including source information.
  gml:operationVersion [0..1]    Version of the coordinate transformation (i.e., instantiation due to the stochastic nature of the parameters). Mandatory when describing a transformation, and should not be supplied for a conversion.
  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.
  from subst. group gml:_positionalAccuracy
  gml:_positionalAccuracyAbstract [0..*]    Unordered set of estimates of the impact of this coordinate operation on point position accuracy. Gives position error estimates for target coordinates of this coordinate operation, assuming no errors in source coordinates.
  gml:sourceCRS [0..1]    Association to the source CRS (coordinate reference system) of this coordinate operation.
  gml:targetCRS [0..1]    Association to the target CRS (coordinate reference system) of this coordinate operation. For constraints on multiplicity of "sourceCRS" and "targetCRS", see UML model of Coordinate Operation package in OGC Abstract Specification topic 2.
  1. gml:usesSingleOperation [2..*]    Ordered sequence of associations to the two or more single operations used by this concatenated operation.
