The work of prepar

12、ing 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 has the right to be represented on that committee. International organizations, governmental and non-governmental, in li

13、aison with 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

14、 technical 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. In other cir

15、cumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is ac

16、cepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of th

17、e committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years

18、, at which time it must either be transformed into an International Standard or be withdrawn.

20、All rights reserved vIntroduction This Technical Specification of the ISO geographic information standards is concerned with the adoption and use of a conceptual schema language (CSL) for developing computer-interpretable models, or schemas, of geographic information. Standardization of geographic i

21、nformation requires the use of a formal CSL to specify unambiguous schemas that can serve as a basis for data interchange and the definition of interoperable services. An important goal of the ISO geographic information standards is to create a framework in which data interchange and service interop

22、erability can be realized across multiple implementation environments. The adoption and consistent use of a CSL to specify geographic information is of fundamental importance in achieving this goal. There are two aspects to this Technical Specification. First, a CSL must be selected that meets the r

23、equirements for rigorous representation of geographic information. This Technical Specification identifies the combination of the Unified Modeling Language (UML) static structure diagram with its associated Object Constraint Language (OCL) and a set of basic type definitions as the conceptual schema

24、 language for specification of geographic information. Secondly, this Technical Specification provides guidelines on how UML should be used to create geographic information and service models that are a basis for achieving the goal of interoperability. One goal of the ISO geographic information stan

25、dards using UML models is that they will provide a basis for mapping to encoding schemas as defined in ISO 19118, as well as a basis for creating implementation specifications for implementation profiles for various environments.

The chosen conceptual s

28、chema language is the Unified Modeling Language (UML). This Technical Specification provides a profile of the Unified Modeling Language (UML) for use with geographic information. In addition, it provides guidelines on how UML should be used to create standardized geographic information and service m

29、odels. 2 Conformance Any conceptual schema written for a specification, including a profile or functional standard, that claims conformance with this Technical Specification shall pass all of the requirements described in the abstract test suite in Annex A. Non-UML schemas shall be considered confor

30、mant if there is a well-defined mapping from a model in the source language into an equivalent model in UML and that this model in UML is conformant. 3 Normative references The following referenced documents are indispensable for the application of this document.

34、ines concepts of a universe of discourse ISO 19101 4.1.4 conceptual schema formal description of a conceptual model ISO 19101 4.1.5 data type specification of a value domain with operations allowed on values in this domain EXAMPLE Integer, Real, Boolean, String, Date and SG Point (conversion of data

35、 into a series of codes). NOTE Data types include primitive predefined types and user-definable types. 4.1.6 domain well-defined set NOTE Domains are used to define the domain set and range set of attributes, operators and functions. 4.1.7 feature abstraction of real world phenomena ISO 19101 NOTE 1

36、 A feature may occur as a type or an instance. Feature type or feature instance should be used when only one is meant. NOTE 2 In UML 8a feature is a property, such as operation or attribute, which is encapsulated as part of a list within a classifier, such as interface, class or data type. 4.1.8 fea

37、ture association relationship that links instances of one feature type with instances of the same or a different feature type ISO 19109 NOTE 1 A feature association may occur as a type or an instance. Feature association type or feature association instance is used when only one is meant. NOTE 2 Fea

38、ture associations include aggregation of features. 4.1.9 feature attribute characteristic of a feature ISO 19101 NOTE 1 A feature attribute has a name, a data type, and a value domain associated to it. A feature attribute for a feature instance also has an attribute value taken from the value domain

39、. NOTE 2 A feature attribute may occur as a type or an instance. Feature attribute type or feature attribute instance should be used when only one is meant.

The result of this operation is to raise the level of water

41、 in a reservoir. EXAMPLE 2 An operation by a “dam” might be to block vessels from navigating along a “watercourse”. NOTE Feature operations provide a basis for feature type definition. 4.1.11 metadata data about data ISO 19115 4.1.12 metadata element discrete unit of metadata ISO 19115 NOTE 1 Metada
