At DIN the Committee responsible for this standard is NA 005-03-03 AA "Kartographie und Geoinformation (Sp CEN/TC 287+ISO/TC 211)" ("Cartography and geographic information (Sp CEN/TC 287+ISO/TC 211)"). 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 on 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 describe 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 ISO 19115:2005-05. The International draft standard has been prepared by ISO/TC 211 "Geographic information/Geomatics". On the European level the responsible Committee is CEN/TC 287 "Geographic information". Working Committee NA 005-03-03 AA "Kartographie und Geoinformation" ("Cartography and geographic information") of NABau is responsible for the German draft standard.
