12.6.3.7 Conversion

element name=Conversion type=gml:ConversionType substitutionGroup=gml:AbstractGeneralConversion complexType name=ConversionType complexContent extension base=gml:AbstractGeneralConversionType sequence element ref=gml:method element ref=gml:parameterValue minOccurs=0 maxOccurs=unbounded sequence extension complexContent complexType gml:Conversion is a concrete operation on coordinates that does not include any change of Datum. The best- known example of a coordinate conversion is a map projection. The parameters describing coordinate conversions are defined rather than empirically derived. Note that some conversions have no parameters. This concrete complex type can be used without using a GML application schema that defines operation-method- specialized element names and contents, especially for methods with only one Conversion instance.

12.6.3.8 method

element name=method type=gml:OperationMethodPropertyType gml:method is an association role to the operation method used by a coordinate operation.

12.6.3.9 parameterValue

element name=parameterValue type=gml:AbstractGeneralParameterValuePropertyType gml:parameterValue is a composition association to a parameter value or group of parameter values used by a coordinate operation.

12.6.3.10 ConversionPropertyType

complexType name=ConversionPropertyType sequence minOccurs=0 element ref=gml:Conversion sequence attributeGroup ref=gml:AssociationAttributeGroup complexType gml:ConversionPropertyType is a property type for association roles to a concrete general-purpose conversion, either referencing or containing the definition of that conversion.
