12.3.3.24 linearCS

element name=linearCS type=gml:LinearCSPropertyType gml:linearCS is an association role to the linear coordinate system used by this CRS.

12.3.3.25 polarCS

element name=polarCS type=gml:PolarCSPropertyType gml:polarCS is an association role to the polar coordinate system used by this CRS.

12.3.3.26 userDefinedCS

element name=userDefinedCS type=gml:UserDefinedCSPropertyType gml:userDefinedCS is an association role to the user defined coordinate system used by this CRS.

12.3.3.27 engineeringDatum

element name=engineeringDatum type=gml:EngineeringDatumPropertyType gml:engineeringDatum is an association role to the engineering datum used by this CRS.

12.3.3.28 EngineeringCRSPropertyType

complexType name=EngineeringCRSPropertyType sequence minOccurs=0 element ref=gml:EngineeringCRS sequence attributeGroup ref=gml:AssociationAttributeGroup complexType gml:EngineeringCRSPropertyType is a property type for association roles to an engineering coordinate reference system, either referencing or containing the definition of that reference system.

12.3.3.29 ImageCRS

All Rights Reserved. gml:ImageCRS is an engineering coordinate reference system applied to locations in images. Image coordinate reference systems are treated as a separate subtype because the definition of the associated image datum contains two attributes not relevant to other engineering datums.

12.3.3.30 affineCS

element name=affineCS type=gml:AffineCSPropertyType gml:affineCS is an association role to the affine coordinate system used by this CRS.

12.3.3.31 imageDatum

element name=imageDatum type=gml:ImageDatumPropertyType gml:imageDatum is an association role to the image datum used by this CRS.

12.3.3.32 ImageCRSPropertyType

complexType name=ImageCRSPropertyType sequence minOccurs=0 element ref=gml:ImageCRS sequence attributeGroup ref=gml:AssociationAttributeGroup complexType gml:ImageCRSPropertyType is a property type for association roles to an image coordinate reference system, either referencing or containing the definition of that reference system.

12.3.3.33 TemporalCRS
