19、0 without any modification. 3 Introduction 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 remote sensing data

20、, 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 process and the prope

21、rties 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 metadata model does pr

22、ovide 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 for these data was

23、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 structure to more

24、extensively describe the derivation of geographic imagery and gridded data. This structure is intended to augment ISO 19115. DIN EN ISO 19115-2:2010-05 EN ISO 19115-2:2010 (E) 4 1 Scope This part of ISO 19115 extends the existing geographic metadata standard by defining the schema required for descr

25、ibing imagery and gridded data. It provides information about the properties of the measuring equipment used to acquire the data, the geometry 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 de

26、scribe the derivation of geographic information from raw data, including the properties of the measuring system, and the numerical methods and computational procedures used in the derivation. The metadata required to address coverage data in general is addressed sufficiently in the general part of I

27、SO 19115. 2 Conformance 2.1 Conformance requirements Metadata shall be provided as specified in Clause 6 and Annexes A and B of this part 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 specifi

28、ed in ISO 19115:2003, Annex C. Any metadata claiming conformance with this part of ISO 19115 shall pass the requirements described in Annex 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 1

29、9115 shall conform to the rules for creating a profile given in ISO 19115:2003, C.6. 3 Normative references The following referenced documents are indispensable for the application of this document.
