气象及海洋卫星遥感信息核心元数据研究

Core Metadata for Remote Sensing Data of Meteorological and Oceanic Satellite

针对气象及海洋卫星遥感信息的共享与应用需求,该文研究了其核心元数据的表达方式,初步设计了核心元数据的框架模型,主要包括标识信息、数据质量信息、分发信息、参照系信息和限制信息等6个子集,并对各子集的元素进行了构建,为数据的发现、获取和应用提供信息,以提高气象海洋卫星遥感信息的应用效能。

Aiming to the sharing and applying requirements on the remote sensing data of the meteorological and oceanic satellite,the paper studied the expression of the core metadata,preliminary designed the framework of the core metadata including identification,data quality,distribution,reference system and constraints information,and constructed the elements, which provides information for data discovery,data access and data application and improves the efficiency of the data of the meteorological and oceanic satellite.
