中国极地测绘空间数据元数据管理系统的设计与实现

本文在对历次极地考察所获得的极地测绘空间数据进行整理、分类的基础上,参考国际标准化组织(ISO/TC211)元数据标准、美国联邦地理数据委员会(FGDC)的CSDGM以及中国可持续发展信息共享元数据标准,制定了能够描述中国极地测绘空间数据的元数据标准,基于此设计并实现了中国极地测绘空间数据元数据管理系统。在网络环境下实现了对元数据的浏览、新增、编辑、查询以及网上发布,从而更好地服务于极地科学考察。

DESIGN AND IMPLEMENTATION OF THE MANAGEMENT SYSTEM OF CHINESE POLAR SPATIAL DATA OF SURVEYING AND MAPPING METADATA

It is very important for most polar users to get the surveying and mapping spatial data information from various districts. The information distribution technique based on Internet can play a great role in the service. In order to allow polar users to know something about the production of surveying and mapping spatial data in time, the management system of metadata must be set up. Through Internet, polar users will be able to query what surveying and mapping spatial data is being produced, how about its quality, where it is produced, and so on.In this paper, different classes and properties of the Chinese polar spatial data of surveying and mapping have been analyzed,and the metadata and its management system have been designed by referring some popular metadata standards such as ISO/TC211, FGDC, and China Sustainable Development Sharing Information Metadata Standard . It is only after searching and querying corresponding surveying and mapping spatial data metadata that users can clearly know what surveying and mapping spatial data is available for them, what surveying and mapping spatial data they are interested in, where the information is stored. So, this metadata management system can serve the polar research expedition well.
