The work of preparing Internati

21、onal 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 IS

22、O, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Par

23、t 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the

Information about the quality of

28、 available geographic data are vital to the process of selecting a data set in that the value of data are directly related to its quality. A user of geographic data may have multiple data sets from which to choose. Therefore, it is necessary to compare the quality of the data sets to determine which

29、 best fulfils the requirements of the user.The purpose of describing the quality of geographic data is to facilitate the comparison and selection of the data set best suited to application needs or requirements. Complete descriptions of the quality of a data set will encourage the sharing, interchan

30、ge and use of appropriate data sets. Information on the quality of geographic data allows a data producer to evaluate how well a data set meets the criteria set forth in its product specification and assists data users in evaluating a products ability to satisfy the requirements for their particular

31、 application. For the purpose of this evaluation, clearly defined procedures are used in a consistent manner.To facilitate comparisons, it is essential that the results of the quality reports are expressed in a comparable way and that there is a common understanding of the data quality measures that

32、 have been used. These data quality measures provide descriptors of the quality of geographic data through comparison with the universe of discourse. The use of incompatible measures makes data quality comparisons impossible to perform. This International Standard standardizes the components and str

33、uctures of data quality measures and defines commonly used data quality measures.This International Standard recognizes that a data producer and a data user may view data quality from different perspectives. Conformance quality levels can be set using the data producers product specification or a da

34、ta users data quality requirements. If the data user requires more data quality information than that provided by the data producer, the data user can follow the data producers data quality evaluation process flow to get the additional information. In this case the data user requirements are treated

35、 as a product specification for the purpose of using the data producer process flow.The objective of this International Standard is to provide principles for describing the quality for geographic data and concepts for handling quality information for geographic data, and a consistent and standard ma

36、nner to determine and report a data sets quality information. It aims also to provide guidelines for evaluation procedures of quantitative quality information for geographic data.

37、ernational Standard establishes the principles for describing the quality of geographic data. It defines components for describing data quality; specifies components and content structure of a register for data quality measures; describes general procedures for evaluating the quality of geographic d

38、ata; establishes principles for reporting data quality.This International Standard also defines a set of data quality measures for use in evaluating and reporting data quality. It is applicable to data producers providing quality information to describe and assess how well a data set conforms to its

39、 product specification and to data users attempting to determine whether or not specific geographic data are of sufficient quality for their particular application.This International Standard does not attempt to define minimum acceptable levels of quality for geographic data.2 ConformanceAny product
