Abstract:

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.
