gml:OperationMethod

gml:OperationMethod is a method (algorithm or procedure) used to perform a coordinate operation. Most operation methods use a number of operation parameters, although some coordinate conversions use none. Each coordinate operation using the method assigns values to these parameters.
The parameter elements are an unordered list of associations to the set of operation parameters and parameter groups used by this operation method.

Element information

Content

• Sequence [1..1]
  from type gml:DefinitionBaseType
  gml:metaDataProperty [0..*]    deprecated
  gml:description [0..1]    The value of this property is a text description of the object. gml:description uses gml:StringOrRefType as its content model, so it may contain a simple text string content, or carry a reference to an external description. The use of gml:description to reference an external description has been deprecated and replaced by the gml:descriptionReference property.
  gml:descriptionReference [0..1]    The value of this property is a remote text description of the object. The xlink:href attribute of the gml:descriptionReference property references the external description.
  gml:identifier [1..1]    Often, a special identifier is assigned to an object by the maintaining authority with the intention that it is used in references to the object For such cases, the codeSpace shall be provided. That identifier is usually unique either globally or within an application domain. gml:identifier is a pre-defined property for such identifiers.
  gml:name [0..*]    The gml:name property provides a label or identifier for the object, commonly a descriptive name. An object may have several names, typically assigned by different authorities. gml:name uses the gml:CodeType content model. The authority for a name is indicated by the value of its (optional) codeSpace attribute. The name may or may not be unique, as determined by the rules of the organization responsible for the codeSpace. In common usage there will be one name per authority, so a processing application may select the name from its preferred codeSpace.

  1. Choice [1..1]
     • gml:formulaCitation    gml:formulaCitation provides a reference to a publication giving the formula(s) or procedure used by an coordinate operation method.
     from subst. group gml:formula
     gml:formula    gml:formula Formula(s) or procedure used by an operation method. The use of the codespace attribite has been deprecated. The property value shall be a character string.
     gml:methodFormula    deprecated
  2. gml:sourceDimensions [0..1]    gml:sourceDimensions is the number of dimensions in the source CRS of this operation method.
  3. gml:targetDimensions [0..1]    gml:targetDimensions is the number of dimensions in the target CRS of this operation method.
  4. Choice [0..*]
     from subst. group gml:parameter
     gml:parameter    gml:parameter is an association to an operation parameter or parameter group.
