33、ion for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established h
34、as the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Int
35、ernational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Public
36、ation as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

EN ISO 19118:2006 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 17 09:59:08 GMT+00:00 2006, Uncontrolled Copy, (c) BSI vii Introduction This International Standard specifies the requirements for d
38、efining encoding rules to be used for interchange of geographic data within the ISO 19100 series of International Standards. An encoding rule allows geographic information defined by application schemas and standardized schemas to be coded into a system- independent data structure suitable for trans
39、port and storage. The encoding rule specifies the types of data to be coded and the syntax, structure and coding schemes used in the resulting data structure. The resulting data structure may be stored on digital media or transferred using transfer protocols. It is intended to be read and interprete
40、d by computers, but may be in a form that is human readable. The choice of one encoding rule for neutral data interchange does not exclude application domains and individual nations from defining and using their own encoding rules that can be platform dependent or more effective with regards to data
41、 size or processing complexity. XML is a subset of ISO/IEC 8879 and has been chosen because it is independent of computing platform and interoperable with the World Wide Web. This International Standard is divided into three logical sections. The requirements for creating encoding rules based on UML
42、 schemas are specified in Clauses 6 to 8. The requirements for creating encoding service are specified in Clause 9, and the XML based encoding rule is specified in Annex A. The XML based encoding rule is intended to be used for neutral data interchange. It relies on the Extensible Markup Language (X
43、ML) and the ISO/IEC 10646 character set standards. Introductions to XML and ISO/IEC 10646 are given in Annexes C and D, respectively. Annex E contains examples of the application of this International Standard. The geographic information standards are organized in the ISO 19100 series of Internation
44、al Standards. The background, the overall structure of this series of International Standards and the fundamental description techniques are defined in ISO 19101, ISO/TS 19103 and ISO 19104. Users of this International Standard will develop application schemas to capture the semantics of geographic
45、information. An application schema is compiled by integrating elements from a set of standardized conceptual schemas developed in ISO 19107, ISO 19108, ISO 19110, ISO 19111, ISO 19112, ISO 19113, ISO 19115 and ISO 19117, including eventually new standardized conceptual schemas. How this integration
46、will take place is described in ISO 19109. The ISO 19100 series of International Standards also defines a set of common services that shall be available when developing geographic information applications. The common services are generally defined in ISO 19119 and will cover access to and processing
47、 of geographic information according to the common information model. Two service areas are defined more closely in ISO 19116 and ISO 19117. ISO 19105, ISO 19106, ISO 19114 and this International Standard cover implementation issues. EN ISO 19118:2006 Licensed Copy: sheffieldun sheffieldun, na, Fri
