摘要：This paper reviews the present status and major problems of the existing ISO standards related to imagery metadata. An imagery metadata model is proposed to facilitate the development of imagery metadata on the basis of conformance to these standards and combination with other ISO standards related to imagery. The model presents an integrated metadata structure and content description for any imagery data for finding data and data integration. Using the application of satellite data integration in CEOP as an example, satellite imagery metadata is developed, and the resulting satellite metadata list is given.
