随着遥感技术的不断进步,各种类型的新型传感器不断涌现,遥感数据源呈现高时间分辨率、高空间分辨率和高光谱分辨率的发展趋势,数据类型越来越多,数据量越来越大。对于这些海量遥感数据必须采用有效的存储、管理和检索。首先分析了遥感编目数据的特点,在对构建高性能、高可靠和可维护的遥感卫星数据目录服务系统的关键技术进行研究的基础上,实现了新型的目录服务系统,并描述了该系统实现的功能。

With the development of the remote sensing technology,many new types of remote sensing sensor are being developed immediately and used for earth observation.Large numbers of earth images,which are very important to research earth,are obtained.As remote sensing satellite data has a tendency to become high temporal,spatial and spectral resolution,its volume is increasing sharply.It is a great problem on how to efficiently restore,manage and search mass of remote sensing satellite data.And satellite data catalogue and archive system,a mass storage and searching web-based system,is just the tool to solve the problem.In order to develop high efficient,high reliable and maintainable archive and catalogue system,the characteristics of satellite data's metadata are analyzed in the paper firstly,which determine the structure of storage organization.Then some critical technology on developing new type of archive and catalogue system are provided,including mass storage,spatial data storage,the implementation of high reliable system,archive and catalogue database's optimization.At last,archive and catalogue system's hardware structure is shown and its main functions are introduced briefly and an example of searching RESOURCESAT-1 satellite data is given.
