The work of preparing Interna

20、tional Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with

21、ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical

22、committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to t

23、he possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 19117 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics. This second edition cancels and

24、replaces the first edition (ISO 19117:2005), which has been technically revised. BS EN ISO 19117:2014ISO 19117:2012(E) ISO 2012 All rights reserved vIntroduction This International Standard specifies a conceptual schema for portrayal data, in particular symbols and portrayal functions. Portrayal fun

25、ctions associate features with symbols for the portrayal of the features on maps and other display media. This schema includes classes, attributes, associations and operations that provide a common conceptual framework that specifies the structure of and interrelationships between features, portraya

26、l functions, and symbols. It separates the content of the data from the portrayal of that data, to allow the data to be portrayed in a manner independent of the dataset. This framework is derived from concepts found in existing portrayal implementations, and specifies a conceptual standard for use i

27、n future implementations (for example OGC Symbology Encoding and Styled Layer Descriptor Profile of WMS). This International Standard provides an abstract model for developers of portrayal systems so that they can implement a system with the flexibility to portray geographic data to a user community

28、 in a manner that makes sense to that community. The principal changes in this revision are to expand the concept of portrayal rules to more generic portrayal functions, include definitions for symbols (including parameterized symbols), include both portrayal functions and symbols in portrayal catal

29、ogues, and define a core portrayal schema, and extensions for specialized cases. This revision for the most part expands on the concepts in ISO 19117:2005, but concepts for portrayal specifications (as a symbol instead of an operation), portrayal catalogue (also includes symbols), and rules-based po

30、rtrayal (multiple rules allowed) have been changed. BS EN ISO 19117:2014BS EN ISO 19117:2014INTERNATIONAL STANDARD ISO 19117:2012(E) ISO 2012 All rights reserved 1Geographic information Portrayal 1 Scope This International Standard specifies a conceptual schema for describing symbols, portrayal func

31、tions that map geospatial features to symbols, and the collection of symbols and portrayal functions into portrayal catalogues. This conceptual schema can be used in the design of portrayal systems. It allows feature data to be separate from portrayal data, permitting data to be portrayed in a datas

32、et independent manner. This International Standard is not applicable to the following: standard symbol collection (e.g. International Chart 1 IHO); a standard for symbol graphics (e.g. scalable vector graphics SVG); portrayal services (e.g. web map service); capability for non-visual portrayal (e.g.

33、 aural symbology); dynamic rendering (e.g. on the fly contouring of tides); portrayal finishing rules (e.g. generalization, resolve overprinting, displacement rules); 3D symbolization (e.g. simulation modeling). 2 Conformance Any portrayal catalogue, portrayal function and symbol describing the port

34、rayal of geographic information claiming conformance with this International Standard shall pass the relevant tests of the abstract test suite presented in Annex A, and those portrayal extension requirements that are applicable to the extension or extensions being used. Conformance classes are defin

35、ed for the portrayal core, and the core plus extensions. These extensions provide additional functionality, and are not mutually exclusive of each other.
