18、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 has t

19、he 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. Interna

20、tional 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. Publicatio

21、n 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 of patent rights. ISO shall not be held responsible for identifying any or all such patent rights

22、. ISO 19115-2 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics. ISO 19115 consists of the following parts, under the general title Geographic information Metadata: Geographic information Metadata Part 2: Extensions for imagery and gridded data BS EN ISO 19115-2:2010IS

23、O 19115-2:2009(E) ISO 2009 All rights reserved vIntroduction Imagery and gridded data are important information sources and products used within a geospatial environment by geographic information systems. The production of imagery and gridded data follows one or more process chains that begin with r

24、emote sensing data, scanned maps, field data collection or other sensing methods and end with the creation of the end data products. The production process needs to be documented in order to maintain quality control over the end products. In addition, metadata about the geometry of the measuring pro

25、cess and the properties of the measuring equipment need to be retained with the raw data in order to support the production process. Within the suite of ISO geographic information standards, ISO 19115 defines the guidelines for describing geographic information and services. While the ISO 19115 meta

26、data model does provide some provisions for imagery and gridded data, the requirements were not fully developed at the time ISO 19115:2003 was drafted. To permit the development of ISO 19115 to proceed, inclusion of metadata definitions for imagery and gridded data was deferred until the framework f

27、or these data was more fully specified within the suite of ISO geographic information standards. Additionally, other standards that implement metadata for imagery and gridded data have been surveyed and are described in ISO/TR 19121. The object of this part of ISO 19115 is to provide the additional

28、structure to more extensively describe the derivation of geographic imagery and gridded data. This structure is intended to augment ISO 19115.

29、Extensions for imagery and gridded data 1 Scope This part of ISO 19115 extends the existing geographic metadata standard by defining the schema required for describing imagery and gridded data. It provides information about the properties of the measuring equipment used to acquire the data, the geom

30、etry of the measuring process employed by the equipment, and the production process used to digitize the raw data. This extension deals with metadata needed to describe the derivation of geographic information from raw data, including the properties of the measuring system, and the numerical methods

31、 and computational procedures used in the derivation. The metadata required to address coverage data in general is addressed sufficiently in the general part of ISO 19115. 2 Conformance 2.1 Conformance requirements Metadata shall be provided as specified in Clause 6 and Annexes A and B of this part

32、of ISO 19115 and ISO 19115:2003, Clause 6 and Annexes A and B. User-defined metadata extensions to this part of ISO 19115 shall be defined and provided as specified in ISO 19115:2003, Annex C. Any metadata claiming conformance with this part of ISO 19115 shall pass the requirements described in Anne

33、x C of this part of ISO 19115 and the abstract test suite presented in ISO 19115:2003, Annex D. 2.2 Metadata profiles Any profile conforming to this part of ISO 19115 shall conform to the rules for creating a profile given in ISO 19115:2003, C.6. 3 Normative references The following referenced docum
