Design And Implementation Of The Chinese Polar Spatial Data Of Surveying And Mapping Management System

In the past 20 years, through the effort by the Chinese Polar National Research Expedition, Chinese scientists have obtained and accumulated the rich and varied polar spatial data of surveying and mapping. In order to rescue and protect these valuable polar scientific data resource, Chinese Polar Spatial Data of Surveying and Mapping Management System is set up. By utilizing this system, we can offer Chinese polar spatial data of surveying and mapping for anyone who needs them.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 . On the basis of it, a method of data organization and management has been provided and the database of the Chinese polar spatial data of surveying and mapping is established.This paper introduces the design methods, the system structures, the database structure and the system functions for the Chinese Polar Spatial Data of Surveying and Mapping Management System. Firstly, this system will be available on all platforms and operation systems. Users can start up this system with any WWW browser, such as Internet Explorer and Netscape Communicator. Secondly, by using technology of the database, manufacturing technology of the webpage and network service technology, this system provides the scanning, adding, editing, inquiring data functions and can publish data on Internet. Lastly, users who are accredited to manage data can get data information. In a word, this system changes the traditional method of preserving data and realizes the data's dynamic updating maintenance and improves the efficiency of the work, so as to serve the polar research expedition well.
