The aim of this standard is to define an interface for the exchange of geographic information where exact knowledge about what feature types will be managed is unnecessary at the time of development of an inter-face. Secondary, it may form the basis for the definition of storage structures and for the development of applications, especially export and import routines.
This standard defines a type independent feature model and a catalogue model for feature type catalogues. The two models may together be used for type independent representation and data exchange within arbi-trary fields of application.
This standard contains:
— application schema for the representation of contents in feature type catalogues
— application schema for type independent representation of geographic features For a geographic dataset utilising this standard may:
— the permitted content of the dataset, including type of spatial representation, be specified in the feature type catalogue
— the meaning of data be interpreted
NOTE ISO 19110 only supports catalogue contents with the latter purpose.
The schemas of this standard support
— classification and definition of feature types
— classification and definition of characteristics of feature types
— definition of value domains, including references to standardised value domains in the ISO 19100 series (representation of geometry, topology, temporal aspects, quality and other metadata etc.)
— classification and definition of associations between feature types, among them aggregates
— generalisation/specialisation of feature types
— digital representation of phenomena, characteristics and associations
— grouping of feature types and value domains within a catalogue
— period of validity for definitions in the feature type catalogue
— management of different versions of features over time
