The work of preparing International Standards is normally carried out through ISO technical committees. Ea

15、ch 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 ISO, also take part in the work. ISO collaborates closely with the Internatio

16、nal 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 committees is to prepare International Standards. Draft International Standar

17、ds 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 the possibility that some of the elements of this document may be the subject

Information about the quality of available geograp

20、hic datasets is vital to the process of selecting a dataset in that the value of data is directly related to its quality. Data users confront situations requiring different levels of data quality. Extremely accurate data is required by some data users for certain needs and less accurate data are suf

21、ficient for other needs. Information about the quality of geographic data is becoming a decisive factor for its utilization as technological advances allow the collection and use of geographic datasets whose quality can exceed that which is needed and requested by data users. The purpose of describi

22、ng the quality of geographic data is to facilitate the selection of the geographic dataset best suited to application needs or requirements. Complete descriptions of the quality of a dataset will encourage the sharing, interchange and use of appropriate geographic datasets. A geographic dataset can

23、be viewed as a commodity or product. Information on the quality of geographic data allows a data producer or vendor to validate how well a dataset meets the criteria set forth in its product specification and assists a data user in determining a products ability to satisfy the requirements for their

24、 particular application. 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.

26、ll rights reserved 1Geographic information Quality principles 1 Scope This International Standard establishes the principles for describing the quality of geographic data and specifies components for reporting quality information. It also provides an approach to organizing information about data qua

27、lity. This International Standard is applicable to data producers providing quality information to describe and assess how well a dataset meets its mapping of the universe of discourse as specified in the product specification, formal or implied, and to data users attempting to determine whether or

28、not specific geographic data is of sufficient quality for their particular application. This International Standard should be considered by organizations involved in data acquisition and purchase, in such a way that it makes it possible to fulfil the intentions of the product specification. It can a

29、dditionally be used for defining application schemas and describing quality requirements. As well as being applicable to digital geographic data, the principles of this International Standard can be extended to identify, collect and report the quality information for a geographic dataset, its princi

30、ples can be extended and used to identify, collect and report quality information for a dataset series or smaller groupings of data that are a subset of a dataset. Although this International Standard is applicable to digital geographic data, its principles can be extended to many other forms of geo

31、graphic data such as maps, charts and textual documents. This International Standard does not attempt to define a minimum acceptable level of quality for geographic data. 2 Conformance Any product claiming conformance with this International Standard shall pass all the requirements described in the

32、abstract test suite presented in Annex A. 3 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amend

35、cy closeness of agreement between a test result and the accepted reference value ISO 3534-1 NOTE A test result can be observations or measurements. 4.2 conformance fulfilment of specified requirements ISO 19105 4.3 conformance quality level threshold value or set of threshold values for data quality

36、 results used to determine how well a dataset meets the criteria set forth in its product specification or user requirements ISO 19114 4.4 data quality date date or range of dates on which a data quality measure is applied 4.5 data quality element quantitative component documenting the quality of a

37、dataset ISO 19101 NOTE The applicability of a data quality element to a dataset depends on both the datasets content and its product specification, the result being that all data quality elements may not be applicable to all datasets. 4.6 data quality evaluation procedure operation(s) used in applyi

38、ng and reporting quality evaluation methods and their results 4.7 data quality measure evaluation of a data quality subelement EXAMPLE The percentage of the values of an attribute that are correct. 4.8 data quality overview element non-quantitative component documenting the quality of a dataset ISO

39、19101 NOTE Information about the purpose, usage and lineage of a dataset is non-quantitative quality information. 4.9 data quality result value or set of values resulting from applying a data quality measure or the outcome of evaluating the obtained value or set of values against a specified conform

40、ance quality level EXAMPLE A data quality result of “90” with a data quality value type of “percentage” reported for the data quality element and its data quality subelement “completeness, commission” is an example of a value resulting from applying a data quality measure to the data specified by a

41、data quality scope. A data quality result of “true” with a data quality value type of “boolean variable” is an example of comparing the value (90) against a specified acceptable conformance quality level (85) and reporting an evaluation of a kind, pass or fail. 4.10 data quality scope extent or char

43、ality scope for a dataset can comprise a dataset series to which the dataset belongs, the dataset itself, or a smaller grouping of data located physically within the dataset sharing common characteristics. Common characteristics can be an identified feature type, feature attribute, or feature relati

44、onship; data collection criteria; original source; or a specified geographic or temporal extent. 4.11 data quality subelement component of a data quality element describing a certain aspect of that data quality element 4.12 data quality value type value type for reporting a data quality result EXAMP

45、LE “boolean variable”, “percentage”, “ratio” NOTE A data quality value type is always provided for a data quality result. 4.13 data quality value unit value unit for reporting a data quality result EXAMPLE “metre” NOTE A data quality value unit is provided only when applicable for a data quality res

46、ult. 4.14 dataset identifiable collection of data ISO 19115 NOTE A dataset may be a smaller grouping of data which, though limited by some constraint such as spatial extent or feature type, is located physically within a larger dataset. Theoretically, a dataset may be as small as a single feature or

47、 feature attribute contained within a larger dataset. 4.15 dataset series collection of datasets sharing the same product specification ISO 19115 4.16 feature abstraction of real world phenomena ISO 19101 NOTE A feature may occur as a type or an instance. Feature type or feature instance should be u

48、sed when only one is meant. 4.17 feature attribute characteristic of a feature ISO 19101 NOTE A feature attribute has a name, a data type and a value domain associated with it. A feature attribute for a feature instance also has an attribute value taken from the value domain. 4.18 feature operation

49、operation that every instance of a feature type may perform ISO 19110 EXAMPLE 1 An operation upon the feature type “dam” is to raise the dam. The result of this operation is to raise the level of water in a reservoir. EXAMPLE 2 An operation by the feature type “dam” might be to block vessels from navigating along a watercourse.
