General Feature Catalog (GFC)

General Feature Catalog (GFC) Version: 1.1



GFC 1.1 is an XML Schema implementation derived from ISO 19110, Geographic information — Methodology for feature cataloguing. It includes ISO 19110:2005 defines the methodology for cataloguing feature types and specifies how the classification of feature types is organized into a feature catalogue and presented to the users of a set of geographic data. ISO 19110:2005 is applicable to creating catalogues of feature types in previously uncatalogued domains and to revising existing feature catalogues to comply with standard practice. ISO 19110:2005 applies to the cataloguing of feature types that are represented in digital form. Its principles can be extended to the cataloguing of other forms of geographic data. The XML schema was encoded using the rules described in ISO/TS 19139:2007, Clause 8 and implementation approach from ISO/TS 19115-3, Clause 8.

XML Schema for gfc 1.1

gfc.xsd is the XML Schema document to be referenced by XML documents containing XML elements in the gfc 1.1 namespace or by XML Schema documents importing the gfc 1.1 namespace. This XML schema includes (indirectly) all the implemented concepts of the gfc namespace, but it does not contain the declaration of any types.

The XML Schema for gfc 1.1 are available here. A zip archive including all the XML Schema Implementations defined in ISO/TS 19115-3 and related standards is also available.

featureCatalogue.xsd implements the UML conceptual schema defined in ISO 19110, Geographic information — Methodology for feature cataloguing. It was created using the encoding rules defined in ISO 19118, ISO 19139, and the implementation approach described in ISO 19115-3 and contains the following classes (codeLists are bold): FC_AssociationRole, FC_Binding, FC_BoundAssociationRole, FC_BoundFeatureAttribute, AbstractFC_CarrierOfCharacteristics, FC_Constraint, FC_DefinitionReference, FC_DefinitionSource, FC_FeatureAssociation, FC_FeatureAttribute, FC_FeatureCatalogue, FC_FeatureOperation, FC_FeatureType, FC_InheritanceRelation, FC_ListedValue, FC_LocalisedDefinitionReference, AbstractFC_PropertyType, and FC_RoleType
